Angiofibroma: A benign neoplasm of fibrous tissue in which there are numerous small and large, frequently dilated, vascular channels. (Stedman, 25th ed)Nasopharyngeal Neoplasms: Tumors or cancer of the NASOPHARYNX.Nose Neoplasms: Tumors or cancer of the NOSE.Neoplasms, Muscle Tissue: Neoplasms composed of muscle tissue: skeletal, cardiac, or smooth. The concept does not refer to neoplasms located in muscles.Nasal Obstruction: Any hindrance to the passage of air into and out of the nose. The obstruction may be unilateral or bilateral, and may involve any part of the NASAL CAVITY.Facial NeoplasmsCheek: The part of the face that is below the eye and to the side of the nose and mouth.Epistaxis: Bleeding from the nose.Endoscopy: Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.Pterygopalatine Fossa: A small space in the skull between the MAXILLA and the SPHENOID BONE, medial to the pterygomaxillary fissure, and connecting to the NASAL CAVITY via the sphenopalatine foramen.Lipoma: A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.Embolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.Oropharyngeal Neoplasms: Tumors or cancer of the OROPHARYNX.Telangiectasia, Hereditary Hemorrhagic: An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.Arteriovenous Malformations: Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.Intracranial Arteriovenous Malformations: Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.Activin Receptors, Type II: One of the two types of ACTIVIN RECEPTORS. They are membrane protein kinases belonging to the family of PROTEIN-SERINE-THREONINE KINASES. The major type II activin receptors are ActR-IIA and ActR-IIB.Orbital Diseases: Diseases of the bony orbit and contents except the eyeball.BostonTomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Surgery, Computer-Assisted: Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.Angiomyoma: A benign tumor consisting of vascular and smooth muscle elements.Cementoma: An odontogenic fibroma in which cells have developed into cementoblasts and which consists largely of cementum.Fatal Outcome: Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.Nasal Cartilages: Hyaline cartilages in the nose. There are five major nasal cartilages including two lateral, two alar, and one septal.Rhinoplasty: A plastic surgical operation on the nose, either reconstructive, restorative, or cosmetic. (Dorland, 28th ed)Nasal Septum: The partition separating the two NASAL CAVITIES in the midplane. It is formed by the SEPTAL NASAL CARTILAGE, parts of skull bones (ETHMOID BONE; VOMER), and membranous parts.Turbinates: The scroll-like bony plates with curved margins on the lateral wall of the NASAL CAVITY. Turbinates, also called nasal concha, increase the surface area of nasal cavity thus providing a mechanism for rapid warming and humidification of air as it passes to the lung.Ethmoid Sinus: The numerous (6-12) small thin-walled spaces or air cells in the ETHMOID BONE located between the eyes. These air cells form an ethmoidal labyrinth.Epiglottis: A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.AustriaAngiography: Radiography of blood vessels after injection of a contrast medium.Algorithms: A procedure consisting of a sequence of algebraic formulas and/or logical steps to calculate or determine a given task.Mastoid: The posterior part of the temporal bone. It is a projection of the petrous bone.Pharyngeal Diseases: Pathological processes involving the PHARYNX.Nasopharynx: The top portion of the pharynx situated posterior to the nose and superior to the SOFT PALATE. The nasopharynx is the posterior extension of the nasal cavities and has a respiratory function.Palatine Tonsil: A round-to-oval mass of lymphoid tissue embedded in the lateral wall of the PHARYNX. There is one on each side of the oropharynx in the fauces between the anterior and posterior pillars of the SOFT PALATE.Pharyngeal Muscles: The muscles of the PHARYNX are voluntary muscles arranged in two layers. The external circular layer consists of three constrictors (superior, middle, and inferior). The internal longitudinal layer consists of the palatopharyngeus, the salpingopharyngeus, and the stylopharyngeus. During swallowing, the outer layer constricts the pharyngeal wall and the inner layer elevates pharynx and LARYNX.Pharynx: A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).Pharyngeal Neoplasms: Tumors or cancer of the PHARYNX.Surgical Procedures, Minimally Invasive: Procedures that avoid use of open, invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device.Radiology, Interventional: Subspecialty of radiology that combines organ system radiography, catheter techniques and sectional imaging.Encyclopedias as Topic: Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)Angiography, Digital Subtraction: A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.Portal Vein: A short thick vein formed by union of the superior mesenteric vein and the splenic vein.Radiography, Interventional: Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.Skull Base: The inferior region of the skull consisting of an internal (cerebral), and an external (basilar) surface.Skull Base Neoplasms: Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (SKULL NEOPLASMS).Sphenoid Sinus: One of the paired air spaces located in the body of the SPHENOID BONE behind the ETHMOID BONE in the middle of the skull. Sphenoid sinus communicates with the posterosuperior part of NASAL CAVITY on the same side.Neuroendoscopy: PROCEDURES that use NEUROENDOSCOPES for disease diagnosis and treatment. Neuroendoscopy, generally an integration of the neuroendoscope with a computer-assisted NEURONAVIGATION system, provides guidance in NEUROSURGICAL PROCEDURES.Nasal Cavity: The proximal portion of the respiratory passages on either side of the NASAL SEPTUM. Nasal cavities, extending from the nares to the NASOPHARYNX, are lined with ciliated NASAL MUCOSA.Sphenoid Bone: An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).

Overgrowth of oral mucosa and facial skin, a novel feature of aspartylglucosaminuria. (1/70)

Aspartylglucosaminuria (AGU) is a lysosomal storage disorder caused by deficiency of aspartylglucosaminidase (AGA). The main symptom is progressive mental retardation. A spectrum of different mutations has been reported in this disease, one missense mutation (Cys163Ser) being responsible for the majority of Finnish cases. We were able to examine 66 Finnish AGU patients for changes in the oral mucosa and 44 of these for changes in facial skin. Biopsy specimens of 16 oral lesions, 12 of them associated with the teeth, plus two facial lesions were studied histologically. Immunohistochemical staining for AGA was performed on 15 oral specimens. Skin was seborrhoeic in adolescent and adult patients, with erythema of the facial skin already common in childhood. Of 44 patients, nine (20%) had facial angiofibromas, tumours primarily occurring in association with tuberous sclerosis. Oedemic buccal mucosa (leucoedema) and gingival overgrowths were more frequent in AGU patients than in controls (p<0.001). Of 16 oral mucosal lesions studied histologically, 15 represented fibroepithelial or epithelial hyperplasias and were reactive in nature. Cytoplasmic vacuolisation was evident in four. Immunohistochemically, expression of AGA in AGU patients' mucosal lesions did not differ from that seen in corresponding lesions of normal subjects. Thus, the high frequency of mucosal overgrowth in AGU patients does not appear to be directly associated with lysosomal storage or with alterations in the level of AGA expression.  (+info)

Genetic alterations in Ki-ras and Ha-ras genes in juvenile nasopharyngeal angiofibromas and head and neck cancer. (2/70)

CONTEXT: Ras gene mutations have been associated to a wide range of human solid tumors. Members of the ras gene family (Ki-ras, Ha-ras and N-ras) are structurally related and code for a protein (p21) known to play an important role in the regulation of normal signal transduction and cell growth. The frequency of ras mutations is different from one type of tumor to another, suggesting that point mutations might be carcinogen-specific. OBJECTIVES: To study the occurrence of Ki-ras and Ha-ras mutations. We also studied the relative level of Ha-ras mRNA in 32 of the head and neck tumors. DESIGN: Case series. SETTING: University referral unit. PARTICIPANTS: 60 head and neck tumors and in 28 Juvenile Nasopharyngeal Angiofibromas (JNA). DIAGNOSTIC TEST: Using PCR-SSCP we examined the occurrence of Ki-ras and Ha-ras mutations. The relative level of Ha-ras mRNA was examined by Northern blot analysis. RESULTS: None of the head and neck tumors or JNA samples showed evidence of mutations within codons 12, 13, 59 and 61 of Ki-ras or Ha-ras genes. However, 17 (53%) of the tumors where gene expression could be examined exhibited increased levels of Ha-ras mRNA compared with the normal tissue derived from the same patient. CONCLUSIONS: Our results demonstrate for the first time that mutations of Ki-ras and Ha-ras genes are not associated with the development of JNA and confirm previous reports indicating that activating ras mutations are absent or rarely involved in head and neck tumors from western world patients. Furthermore, our findings suggest that overexpression of Ha-ras, rather than mutations, might be an important factor in the development and progression of head and neck tumors.  (+info)

Tonsillar lymphangiomatous polyps: a clinicopathologic series of 26 cases. (3/70)

BACKGROUND: Lymphangiomatous polyps are uncommon benign tumors of the tonsils. METHODS: Twenty-six cases of lymphangiomatous polyps diagnosed between 1980 and 1999 were retrieved from the files of the Otorhinolaryngic-Head and Neck Tumor Registry of the Armed Forces Institute of Pathology. Hematoxylin and eosin-stained slides were reviewed to characterize the histologic features of these tumors. Immunohistochemical stains were performed on 15 cases. Clinical follow-up data were obtained. RESULTS: The patients included 13 males and 13 females, ages 3 to 63 years (mean, 25.2 years). Patients experienced dysphagia, sore throat, and the sensation of a mass in the throat. Symptoms were present from a few weeks to years. The tonsillar masses were unilateral in all cases. Clinically, the lesions were frequently mistaken for a neoplasm (n = 18 patients). Grossly, all of the lesions were polypoid and measured 0.5 to 3.8 cm (mean, 1.6 cm). Histologically, the polyps were covered by squamous epithelium showing variable epithelial hyperplasia, dyskeratosis, and lymphocytic epitheliotropism. The masses showed a characteristic submucosal proliferation of small to medium-sized, endothelial-lined, lymph-vascular channels lacking features of malignancy. Collagen, smooth muscle, and adipose tissue were present in the stroma. Intravascular proteinaceous fluid and lymphocytes were noted. Immunohistochemical findings confirmed the endothelial origin of the vascular proliferation and a mixed lymphoid population. The differential diagnosis included fibroepithelial polyp, lymphangioma, juvenile angiofibroma, and squamous papilloma. In all patients with follow-up, complete surgical excision was curative (mean follow-up, 5.4 years; range, 1 mo to 14 years). CONCLUSIONS: We detail the clinical and pathologic features of tonsillar lymphangiomatous polyps. These tumors are uncommon and may clinically be mistaken for a malignant neoplasm. The characteristic histologic features should allow for its correct diagnosis and differentiation from similar appearing tonsillar lesions.  (+info)

Frequency of facial angiofibromas in Japanese patients with multiple endocrine neoplasia type 1. (4/70)

The high frequency of cutaneous manifestations in patients with multiple endocrine neoplasia type 1 (MEN 1) has recently been reported. Since prevalence of some cutaneous diseases varies among different ethnic groups, we examined the frequency of facial angiofibromas in Japanese patients with familial MEN 1. Among 27 patients with germline MEN1 gene mutation and one asymptomatic gene carrier, angiofibromas were identified in 43% (12/28) of the subjects. This frequency was significantly lower than that of Caucasian patients, but nonetheless almost equaled those of pituitary tumors and pancreas endocrine tumors. Angiofibromas should be considered as one of major manifestations in MEN 1 regardless of patients' ethnic origin, and clinicians should pay careful attention to the cutaneous lesions in patients with endocrine tumors.  (+info)

Frequent beta-catenin mutations in juvenile nasopharyngeal angiofibromas. (5/70)

Juvenile nasopharyngeal angiofibromas (JNAs) are locally aggressive vascular tumors occurring predominantly in adolescent males. The pathogenesis of JNAs is unknown. Recently, JNAs have been reported to occur at increased frequency among patients with familial adenomatous polyposis, suggesting that alterations of the adenomatous polyposis coli (APC)/beta-catenin pathway might also be involved in the pathogenesis of sporadic JNAs. We analyzed somatic beta-catenin and APC gene mutations in 16 sporadic JNAs from nonfamilial adenomatous polyposis patients using immunohistochemistry for beta-catenin, and direct DNA sequencing for exon 3 of the beta-catenin gene and the mutation cluster region of the APC gene. Nuclear accumulation of beta-catenin was diffusely present in the stromal cells but not in the endothelial cells of all 16 JNAs. Activating beta-catenin gene mutations were present in 75% (12 of 16) of JNAs. Six JNA patients also had recurrent tumors after surgery, and in all cases the beta-catenin gene status of the recurrent JNA was identical to the initial tumor. No mutations in the mutation cluster region of the APC gene were detected in the four JNAs without beta-catenin mutations. The high frequency of beta-catenin mutations in sporadic JNAs and the presence of identical beta-catenin gene mutations in recurrent tumors indicates that activating beta-catenin gene mutations are important in the pathogenesis of JNAs. The immunohistochemical localization of beta-catenin only to the nuclei of stromal cells further suggests that the stromal cells, rather than endothelial cells, are the neoplastic cells of JNAs.  (+info)

Clinicopathologic analysis of angiomyofibroblastoma of the female genital tract. (6/70)

OBJECTIVE: To study the clinicopathologic features and immunoprofile of angiomyofibroblastoma (AMF) with emphasis on differential diagnosis. METHODS: Seven vulvar, two vaginal and one perineal angiomyofibroblastomas were evaluated by light microscopy and immunohistochemistry. The immunohistochemical studies were performed on paraffin-embedded sections using the standard ABC method with a panel of antibodies. RESULTS: Angiomyofibroblastoma predominantly occurred in middle-aged women in the genital region, especially in the superficial area of the vulva. Clinically, most of the tumors presented as slowly growing painless masses and were often diagnosed as Bartholin's gland cysts. Histologically, the tumors were all well-circumscribed and characterized by alternating hypocellular and hypercellular areas with abundant thin-walled blood vessels. The tumor cells were bland and spindle-shaped or epithelioid and tended to concentrate around the vessels or cluster in small nests. Immunohistochemically, the tumor cells expressed vimentin and estrogen receptor protein in all 10 cases and desmin in 9 cases. Three cases showed weak or focal immunoreactivity to alpha-smooth muscle actin and muscle specific actin. All ten patients were treated by local excision. Follow-up showed a benign course with no signs of recurrence. CONCLUSIONS: Angiomyofibroblastoma is a distinctive neoplasm that has a propensity to occur in the female genital tract. Recognition of this entity is important to avoid misdiagnosis with other vulvar angiomyxoid neoplasms.  (+info)

Risks of tumor embolization in the presence of an unrecognized patent foramen ovale: case report. (7/70)

A patent foramen ovale (PFO) is a fairly common septal defect in the general population. Paradoxical embolization through a PFO is a known cause of stroke. Preprocedural recognition of a PFO in a patient undergoing particulate arterial embolization can help reduce the risk of cerebral infarction.  (+info)

Recurrent angiofibroma invading the skull base--case report. (8/70)

A 16-year-old male presented with a massive nasopharyngeal angiofibroma arising in the nasopharynx, nasal cavity, pterygopalatine fossa, and infratemporal fossa, and eroding the pterygoid process of the sphenoid bone. Neuroimaging showed the tumor had infiltrated the parasellar region from the middle cranial fossa and reached the cavernous sinus. The tumor was almost completely removed macroscopically by a modified transbasal approach.  (+info)

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign neoplasm that occurs almost exclusively in the nasopharynx of adolescent males. Surgery remains the primary treatment of choice. JNA has always presented a management challenge to surgeons because of its vascular nature, site of occurrence, and local tissue destruction. The surgical approaches are either standard open method which include external or intraoral incisions, or the recent advanced approach, i.e. via using the endonasal endoscope. It is widely accepted that the use of preoperative angiographic embolization reduces the occurrence of intraoperative bleeding and facilitates tumour removal. However, angiographic embolization is not available at all centres. The purpose of this article is to present our experience with five patients diagnosed with JNA who were resected without embolization, using various surgical approaches. Two tumours were removed via endonasal endoscopic surgery. None of the tumours were embolized prior to ...

The present results demonstrate that the contrast-enhanced helical CT enabled the detection of RD in the early postoperative course after JNA involving the skull base was excise. Early postoperative scans had higher specificity (83%) than sensitivity (75%) and higher NPV (83%) than PPV (75%). The range of 95% CIs for the results was wide because of the small number of patients, which reflects the rare occurrence of the disease. The high κ values indicate high interreader consistency in the early detection of RD with CT (15).. When CT depicts RD, the finding should reliably correspond to a true RD at revision surgery. The specificity (83%) and PPV (75%) of early postoperative CT scan was relatively high. Therefore, contrast-enhanced CT may have diagnostic value, as it had relatively high accuracy in the diagnosis of RD while creating minimal patient discomfort.. The sensitivities and NPVs suggest that a patent RD can be detected in most cases. Potential RD may be missed during postoperative CT ...

Juvenile angiofibromas (JNA) are common benign tumors usually occurring in the nasopharynx of male adolescents. They represent 0.5% of head and neck neoplasms and very rarely they localize in extra-nasopharyngeal sites. Extra-nasopharyngeal angiofibroma (ENPA) is histologically similar to JNA. Due to its clinical and epidemiological characteristics, some authors identify the ENPA as a different disease from the typical JNA. Less than a hundred cases of ENPA are reported in literature. Maxillary and ethmoid sinus are the most commonly involved sites, whereas other localizations such as nasal septum and inferior turbinate are infrequent. We report the case of a ENPA arising from the lateral crus of the alar cartilage, the first described in literature, at the best of our knowledges.. ...
Juvenile nasopharyngeal angiofibroma is a locally aggressive benign vascular neoplasm, composed of vasogenic and myofibroblastic elements, accounts for 0.05-0.5% of all the head and neck neoplasms. There are very few case reports of nasopharyngeal angiofibroma involving the oral cavity; we report a case involving both the maxilla and mandible in a 17-year-old patient who reported with a large firm swelling on right side of face with recurrent epistaxis and headache. Magnetic resonance angiography revealed a large lobulated enhancing soft tissue mass, which was hypointense on T1-weighted image and heterogeneously hyperintense on T2-weighted image causing expansion of pterygopalatine fossa and sphenopalatine foramen with extension into the sphenoid sinus, ethmoid air cells, right nasal cavity, right infratemporal fossa and right maxillary sinus with remodeling of right zygomatic arch and part of body and ramus of mandible ...
BACKGROUND: The TNM system is an established tool for classification of solid tumors by means of tumor size and extent, the involvement of local lymph nodes, and the presence of distant metastases. The classification was established in order to visualize prognostic implications and to allow establishment of systematic therapeutic algorithms. Since the beginning of 2017 a revised version of the classification has applied. Particularly the classification of otorhinolaryngologic tumors has been thoroughly revised in the 8th edition, partly on the basis of new prognostically relevant parameters, such as infection with oncogenic human papillomavirus (HPV) subtypes ...

MEN-1, which was first described as a clinical and genetic syndrome by Wermer in 1954, is an autosomal dominant cancer syndrome, characterized primarily by multiple neoplasias in the parathyroid glands, endocrine pancreas and anterior pituitary. Other endocrine tumors such as gastrinoma, carcinoid, adrenal cortical tumors and cutaneous tumors (angiofibroma, collagenoma and lipoma) may also occur. The genetic defect responsible for MEN-1 has been mapped to chromosome 11 q 13 . The MEN-1 gene consists of 10 exons which encodes a protein of 610 amino acids. Inactivation of MEN-1 gene mutations in both germline and sporadic tumors supports that MEN-1 is a tumor-suppessor gene. Germline MEN-1 gene mutation is responsible for the majority of MEN-1 syndrome cases. MEN-1 induces combinations of more than twenty various endocrine and non-endocrine tumors. A feasible definition of MEN-1 is a case with two of the three main MEN-1 related endocrine tumors (parathyroid adenomas, entero-pancreatic endocrine ...

He is known to have epilepsy and is on regular anti-epileptic medication for three years. He is being followed up at a neighborhood medical center at his native village . On physical examination numerous brown papules were seen over his nose and both cheeks in a butterfly pattern which correspond to facial angiofibromas (Figure 1). Ash Leaf Hypomelanotic macules were seen over his extremities (Figure 2). Few hyperpigmented café au lait macules were observed over his trunk (Figure 3). A big fibroma was also seen over his scalp (Figure 4). Areas of thick leathery texture of orange peel known as Shagreen patches were observed on back (Figure 5).. Figure 1: Facial ...
Multiple endocrine neoplasia type 1 (MEN1) is characterized by endocrine tumors, particularly in the parathyroid glands, anterior pituitary, and pancreatic islet cells. Primary tumors may be found in more than one endocrine organ and/or multiple tumors may be found in the same organ. MEN1-associated endocrine tumors cause an array of clinical and biochemical manifestations secondary to hormone hypersecretion: hyperparathyroidism (the most frequent MEN1-symptom with potential effects on the central nervous system (CNS), hypercalcemia, gastrointestinal, renal cardiovascular, and skeletal involvement), hypercortisolism, gigantism and acromegaly, prolactinoma (with associated oligomenorrhea, amenorrhea, and galactorrhea in females and sexual dysfunction in males), gastrinoma, and insulinoma. Non-endocrine tumors also are common and can include facial angiofibromas and collagenomas of the skin, lipomas, meningioma and ependymoma of the CNS, and leiomyomas. MEN1 is caused by mutations in the menin ...
ICS: Intercostal Space, IC: Intercostal, IV: Intervertebral, CD,HV: Castlemans Disease, Hyaline Vascular Type. Several previous reports have demonstrated that Castlemans disease can mimic various tumors, for example: thymoma (1), angiofibroma (2), meningioma (8), pulmonary neoplasms (9), adnexal mass (10), and cervical mass (4). Many lesions exhibit a similar radiological appearance and only a pathologic examination allows an accurate diagnosis. Because Castlemans disease is a rare reactive entity, its diagnosis is generally overlooked by radiologists and clinicians.. In hyaline vascular Castlemans disease, the adherence by an involved lymph node to the adjacent soft tissue has been described (10), however encapsulation and self-limitation are constant features of hyaline vascular Castlemans disease.

Sonographically, AMFB has been reported to be well demarcated with inhomogeneous echogenicity and multiple hypoechoic areas within an echogenic stroma [12]. Wang and coworkers assessed 72 perineal tumors, two among which represented AMFB and were characterized as solid cystic masses on the basis of ultrasonography [13]. In contrast to these descriptions, we found the tumor in our patient to be of homogeneous, medium echogenicity without solid cystic features (see Additional file 1). Retrospectively, the obtained MR images did not add much information to what was already known based on the ultrasound studies.. To date, the exact pathogenesis of AMFB is not clear. Because many tumors express estrogen and progesterone receptors, it is likely that these hormones play a crucial role in the pathogenesis of AMFB. Indeed, these tumors almost exclusively occur in women of reproductive age; two cases of postmenopausal women receiving tamoxifen therapy have been reported [14, 15]. Because many of the ...
Angiomyofibroblastoma is a rare, usually small benign mesenchymal tumor that occurs in vulvar lesions of premenopausal women. A case of angiomyofibroblastoma that arose as a unique pedunculated and particularly large mass in the left vulva of a 48-year-old woman is presented herein. The patient had been aware of a gradually enlarged mass of 7 years duration without any other gynecological symptoms or signs. The maximum dimension of the tumor measured 11 cm. The resected tumor was well circumscribed with a bulging and glistening cut surface. Histological examination revealed an admixture of irregularly distributed hypercellular and hypocellular areas with spindled, plump spindled, or plasmacytoid stromal cells and abundant venular or capillary-sized vessels. Stromal cells characteristically cluster around delicate vessels within an edematous to collagenous matrix. In the present case, intralesional adipose tissue was present throughout the tumor. There was no significant nuclear atypia, and ...

Thiamylal (Surital) is a barbiturate derivative invented in the 1950s. It has sedative, anticonvulsant, and hypnotic effects, and is used as a strong but short acting sedative. Thiamylal is still in current use, primarily for induction in surgical anaesthesia or as an anticonvulsant to counteract side effects from other anaesthetics. It is the thiobarbiturate analogue of secobarbital. Hsieh MY, Hung GY, Hsieh YL, Chang CY, Hwang B.

Case summary: (Case 1) A 27-year-old male patient who was diagnosed with tuberous sclerosis and was referred for ophthalmologic examination. The best corrected visual acuity (BCVA) was 0.63 and macular edema with epiretinal membrane and retinal astrocytic hamartomas were observed on his right eye. And also fluorescent leakage was observed in fluorescein angiography. After one month of intravitreal ranibizumab injection, the BCVA in the right eye was 1.0. Amount of the macular edema was decreased in the optical coherence tomography and remained stable for 6 months. (Case 2) A 34-year-old female patient presented with sudden left visual loss. The patient had a history of 10 years old tuberous sclerosis and had facial angiofibroma. The BCVA was 1.0 in the right eye and 0.2 in the left eye. Bilateral retinal astrocytic hamartomas and vitreous hemorrhage in the left eye were observed. Intravitreal bevacizumab injection was performed twice at her left eye and then she recovered to the BCVA of 1.0 in ...

Y1 - 2013/7. N2 - Spindle cell lipoma is an uncommon histologic variant of lipoma, and reports at the larynx or hypopharynx are extremely rare. We present our experience with a 53-year-old man with a huge spindle cell lipoma of the pyriform sinus and tried to remove the tumor using a transoral robotic approach. The tumor was successfully removed with 3-dimensional visualization providing an excellent view of the resection margin and the dissection plane. Furthermore, geometric resection could be conducted in the narrow pharyngeal lumen and working space using the articulated robotic arms. We suggest that spindle cell lipoma should be considered for differential diagnosis in benign hypopharyngeal tumors and that transoral robotic surgery may be successfully used in huge benign tumors of the hypopharynx..

Patients will be those already diagnosed with TSC (definite, probable, or possible) based on clinical criteria and/or genetic testing, and ranging in age from 18 to 90 years old.. The clinical features of TSC considered of major significance are: facial angiofibromas or forehead plaque, nontraumatic periungual fibromas, three or more hypomelanotic macules, shagreen patch, multiple retinal nodular hamartomas, cortical tuber, subependymal nodule, subependymal giant cell astrocytoma, cardiac rhabdomyoma, lymphangioleiomyomatosis, and renal angiomyolipoma.. The minor features of TSC are: multiple randomly distributed pits in dental enamel, hamartomatous rectal polyps, bone cysts, cerebral white matter radial migration lines, gingival fibromas, nonrenal hamartoma, retinal achromic patch, confetti skin lesions, and multiple renal cysts (5). Definite TSC is diagnosed by the presence of two major features or one major feature plus two minor features. Probable TSC is diagnosed by the presence of one ...

Multiple endocrine neoplasia type 1 (MEN1) is characterized by the occurrence of parathyroid, pancreatic islet and anterior pituitary tumors. Some patients may also develop carcinoid tumors, adrenocortical tumors, facial angiofibromas, collagenomas, and lipomas. MEN1 is an autosomal-dominant disorder, due to mutations in the tumor suppressor gene MEN1, which encodes a 610 amino acid protein, menin. Thus, the finding of MEN1 in a patient has important implications for family members because first-degree relatives have a 50% risk of developing the disease and can often be identified by MEN1 mutational analysis. Patients with MEN1 have a decreased life-expectancy and the outcomes of current treatments, which are generally similar to that for the respective tumors occurring in non-MEN1 patients, are not as successful because of multiple tumors, which may be larger, more aggressive, and resistant to treatment, and the concurrence of metastases. The prognosis for MEN1 patients might be improved by pre
TY - JOUR. T1 - Pulmonary lymphangioleiomyomatosis in a man. AU - Aubry, M. C.. AU - Myers, J. L.. AU - Ryu, J. H.. AU - Henske, E. P.. AU - Logginidou, H.. AU - Jalal, S. M.. AU - Tazelaar, H. D.. PY - 2000. Y1 - 2000. N2 - Pulmonary lymphangioleiomyomatosis (LAM) is an uncommon disease reported to occur exclusively in women. We describe a pheno-typically normal man with pulmonary LAM. Fluorescence in situ hybridization (FISH) studies performed on the lung biopsy confirmed a normal XY genotype. Our patient also had stigmata of tuberous sclerosis complex (TSC), including facial angiofibromas and renal angiomyolipoma. Immunohistochemical stains of both Lam and renal angiomyolipoma showed positive immunoreactivity for hamartin (TSC1) and loss of immunoreactivity for tuberin (TSC2). Loss of heterozygosity (LOH) for TSC2 was further demonstrated in the renal angiomyolipoma. Coupled with the results of immunostains, these findings are consistent with TSC2 mutation..

The benign, non-invasive lesions of tuberous sclerosis can appear in any organ like the brain, heart, skin, eyes, kidney, lung, and liver. Therefore, TS has a wide clinical spectrum. The diagnosis of definitive TS is based on specific clinical features and requires the presence of two major criteria, or one major and two minor [3]. Pulmonary lymphangioleiomyomatosis, renal angiomyolipoma and facial angiofibroma are some of the major clinical features.. The most frequent cause of death in patients with TS is renal complication [3, 5]. Multifocal, bilateral angiomyolipomas are found in about 70-90% of adult patients [3], and the prevalence increases with age, being less frequent in children [3, 4]. These lesions are more often prevalent in women, suggesting a hormonal component to the tumor growth [6]. The angiomyolipomas are composed of varying amounts of mature adipose tissue, smooth muscle, and abnormal blood vessels [3, 6]. The demonstration of intratumoral fat with negative attenuation values ...
