Aims: To assess lymphatic vascular density (LVD) and lymph vessel endothelial proliferation in a series of carcinoma ex pleomorphic adenoma (CXPA) that represents the tumour in the different carcinogenesis phases and tumour progression.. Methods: In 8 cases of early CXPA (intracapsular and minimally invasive tumours), 8 of advanced CXPA (widely invasive tumours) and 10 of pleomorphic adenoma (PA) without malignant transformation, lymphatic vessels and proliferating cells were detected using the antibodies D2-40 and Ki-67 respectively.. Results: Comparing early tumours with advanced ones, LVD was not significantly different at the tumour margin. In contrast, regarding intratumoural lymphatics, PA without malignant transformation and early CXPA contained rare, if any, lymph vessels, whereas in widely invasive carcinomas they were more numerous. However, neither intratumoural nor peritumoural LVD were increased in comparison to adjacent normal salivary gland tissue. In no case did dual ...

N2 - The most common benign tumour of the major salivary glands is the pleomorphic adenoma. They are seen rarely in the minor salivary glands, usually in hard palate, soft palate and nasopharynx. Pleomorphic adenomas in nasal cavity are unusual and may be misdiagnosed because they have predominant myoepithelial cellularity and fewer myxoid stromata compared with those elsewhere. We present a case of 38-year-old male with a 2-year history of left nasal obstruction and epistaxis since 6 months. Diagnostic nasal endoscopic examination showed a soft lobulated mass in left nasal cavity attached to anterior part of the septum. Radiological examination demonstrated soft tissue mass filling left nasal cavity with an eroded septum. The biopsy from the mass was suggestive of pleomorphic adenoma and was resected endoscopically. ...

Salivary gland tumors most commonly occur in the parotid gland, accounting nearly 85% of all salivary gland tumors. But, 25% of parotid tumors are malignant (cancerous).. Pleomorphic adenoma is the most common type of benign salivary gland tumor. It is typically a slow growing tumor and occur most often in the parotid gland. It is also known as mixed tumor which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements.. The tumor is usually solitary and presents as a slow growing, painless and firm singular nodal mass. It is usually mobile unless found in the palate and can cause atrophy of the mandibular ramus when located in the parotid gland.. ...
This study was undertaken to evaluate and concentrate on the recurrent pleomorphic adenomas (PAs) of the parapharyngeal space. The records of 9 patients treated for recurrent PAs occupying parapharyngeal space were retrospectively reviewed. The study population comprised 6 women and 3 men with a mean age of 51 (range, 35-79 years). Before the first revision surgery, imaging studies and clinical examinations showed 1 solitary mass in 4 patients, 2 solitary masses in 3 patients, and 3 or more masses in 2 patients. After first revision surgery, 4 patients had rerecurrences with multinodular disease. Two of 4 patients underwent radiation therapy (RT), and the other 2 patients underwent second revision surgery, among whom 1 patient underwent third revision surgery, and the other one was also submitted to RT. Overall, 12 reoperations were performed, and at the end of all operations, 4 patients had rerecurrences and residual disease. In conclusion, we recommend RT to patients with multinodular disease, ...

Pleomorphic adenoma is a common benign salivary gland neoplasm characterised by neoplastic proliferation of parenchymatous glandular cells along with myoepithelial components, having a malignant potentiality. It is the most common type of salivary gland tumor and the most common tumor of the parotid gland. It derives its name from the architectural Pleomorphism (variable appearance) seen by light microscopy. It is also known as Mixed tumor, salivary gland type, which describes its pleomorphic appearance as opposed to its dual origin from epithelial and myoepithelial elements. The tumor is usually solitary and presents as a slow growing, painless, firm single nodular mass. Isolated nodules are generally outgrowths of the main nodule rather than a multinodular presentation. It is usually mobile unless found in the palate and can cause atrophy of the mandibular ramus when located in the parotid gland. When found in the parotid tail, it may present as an eversion of the ear lobe. Though it is ...
Synchronous pleomorphic adenomas of the major salivary glands: a case report.: The presentation of multiple distinct tumors in major salivary glands is rare. Al
Purpose: We sought to identify genomic alterations (GAs) in salivary gland adenocarcinomas, not otherwise specified (NOS), salivary duct carcinomas (SDC), carcinoma ex pleomorphic adenoma (ca ex PA), and salivary carcinoma, NOS. Experimental design: DNA was extracted from 149 tumors. Comprehensive genomic profiling (CGP) was performed on hybridization-captured adaptor ligation-based libraries of 182 or 315 cancer-related genes plus introns from 14 or 28 genes frequently rearranged for cancer and evaluated for all classes of GAs. Results: 590 GAs were found in 157 unique genes (mean 3.9/tumor). GAs in the PI3K/AKT/mTOR pathway were more common in SDC (53.6%) than other histologies (p=0.019) Cyclin dependent kinase GAs varied amongst all histotypes: adenocarcinoma, NOS (34.6%); SDC (12.2%); ca ex PA (16.7%); carcinoma, NOS (31.2%) (p=0.043).

The surgical risks involved in the removal of the tumor vary with the tumor itself. A smaller, more confined tumor will be easier to remove and therefore be less likely to cause damage to the facial nerve located nearby. A tumor that extends to a wider area may carry heavier risk. According to Georgetown University Hospital, surgeons are extremely careful in working near the facial nerve and most patients heal normally and do not experience any abnormal function. ...

A 68-year-old man was referred to our oculoplastics clinic by his primary ophthalmologist with a three month history of an expanding mass in his left superotemporal orbit. He had been followed yearly with CT scans since a recurrent left lacrimal gland lesion was removed 26 years ago. The initial lesion was resected 13 years prior to that, when the patient was 29 years old. The pathology reports from both surgeries described a pleomorphic adenoma of the lacrimal gland with no malignant criteria. Neither report indicated whether the tumor had been completely resected. The last CT scan was performed almost a year before symptoms started and was read as stable with no tumor recurrence. His only current complaint was of slight episodic pain in the affected area. He denied any diplopia, vision loss, headache or other systemic symptoms. He was also treated for hypertension, hypothyroidism and dyslipidemia ...

CLINICAL PRESENTATION: A 56-year-old Asian man visited our hospital with a chief complaint of visual disturbance caused by brain tumor that filled up the sella turcica with suprasellar extension. The patient underwent craniotomy via a left pterional approach, and the subdural, intracranial portion of the tumor was totally removed, with every artery and nerve preserved. Pathological diagnosis of the tumor was intrasellar salivary gland-like pleomorphic adenoma. Three years after the operation, the patient remains free from tumor recurrence. CONCLUSION: Tumors in ...
Discussion: Myoepithelial carcinomas (or malignant myoepitheliomas) are rare malignant salivary gland neoplasms in which the tumor cells show myoepithelial differentiation. The entity was first described by Stromeyer et al. in 1975. The tumor was included in the WHO classification of salivary gland neoplasms as a distinct clinicopathologic entity in 1991. About 60% to 70% of myoepithelial carcinomas develop in a benign mixed tumor (carcinoma ex pleomorphic adenoma), and the remainder arise de novo. Histologically, malignant myoepitheliomas are composed of one or several cell types: spindle, plasmacytoid, epithelioid, and clear cells. Frequently, one of the cell types predominates. The neoplastic cells grow either as multiple nodules or as large solid sheets separated by variable amounts of intervening hyaline or myxoid stroma. By far, the multinodular growth pattern is more prevalent. The cytologic features generally reflect the histology. The cytologic smear can show spindle, epithelioid or ...
OBJECTIVE: The aim of this study was to report the clinicopathological features of 18 epithelial tumors of the lacrimal gland treated in a single institution. STUDY DESIGN AND SETTING: Clinical data and treatment were recorded and histological features reviewed. RESULTS: Twelve tumors (66.7%) were adenoid cystic carcinoma (ACC), 5 (27.8%) pleomorphic adenoma (PA), and 1 (5.5%) carcinoma ex pleomorphic adenoma. All patients with ACC presented with advanced clinical stage, and most were treated by wide surgical resection followed by adjuvant radiotherapy. No recurrence was observed in 4 cases of ACC; however, 7 patients died from persistence of disease or by local and/or distant recurrence. All PA patients were successfully treated by surgical resection. CONCLUSIONS: Epithelial lacrimal gland tumors are mainly PA and ACC, and malignancies are more common than benign tumors. Although ACC presented typically with advanced clinical stage, 33% of the patients survived without tumor recurrence or ...

Chordomas are rare tumors that are usually located in the sacrococcygeal and sphenooccipital region. Their cytologic diagnosis is rather straightforward when sampled by fine-needle aspiration (FNA) from these characteristic locations, especially when physalipherous cells are present. However, chordomas may pose difficult diagnostic challenges when encountered in unusual locations, such as the parapharyngeal region. We report the cytologic findings of a recurrent chordoma sampled through transoral FNA from the parapharyngeal space of a 66-year-old woman. As the prior history of chordoma was not available during the rapid onsite evaluation, the presence of bland epithelioid nonvacuolated cells and spindle cells intimately admixed with a fibrillary, intensely metachromatic material led to an initial diagnosis of pleomorphic adenoma. Review of the patients prior pathology specimen and of the Papanicolaou-stained smears and cellblock sections showing rare multivacuolated (physalipherous) cells led ...
Abstract Introduction: Polymorphous low grade adenocarcinoma (PLGA) is a rare salivary gland neoplasm with an indolent course. It occurs primarily in the minor salivary glands but can rarely occur in the major salivary glands. It usually occurs in the fifth to seventh decades of life with female preponderance. Case Report: A 16-year-old male presented with recurrent painless swelling in the right preauricular region and with a history of surgical intervention at the same site in the past. His histopathology report was suggestive of pleomorphic adenoma. The swelling recurred after one year of excision and a superficial parotidectomy was performed. The detailed histopathological examination was suggestive of Polymorphous low grade adenocarcinoma. In view of close margins, the patient was given adjuvant radiotherapy. Thirty-three months post-surgery, he is alive and disease-free. We describe a rare case of PLGA of the parotid gland in a teenager with its clinical characteristics, histopathological
E-cadherin is a calcium dependent cell adhesion molecule, important in cell to cell interactions in epithelial tissues. The present study examined E-cadherin expression in normal salivary glands, pleomorphic adenoma, Warthins tumor, mucoepidermoid carcinoma, acinic cell carcinoma, adenoid cystic carcinoma and adenocarcinoma of salivary glands in paraffin sections using a monoclonal antibody (5H9). This study is firstly reported E-cadherin expression in the salivary gland and tumors.,BR,In normal submandibular and parotid gland, E-cadherin staining was confined to the cell membrane of acinar and ductal cells. In excretory ducts, high columnar cells showed the strongest reaction at the basal aspect and ductal basal cells were weakly positive or negative, the basement membrane zone lacked staining. No E-cadherin reaction was observed in modified myoepithelial cells and plasmacytoid cells. In pleomorphic adenoma and mucoepidermoid carcinoma, E-cadherin was positive at the lateral cell membrane or ...
Canalicular adenoma is a type of benign salivary gland tumor that occurs most often in minor salivary glands. In addition to pleomorphic adenoma, the two are the most common tumors of the upper lip. In 95% of cases, canalicular adenoma occurs on the upper lip. The next most common location is the buccal mucosa (inner cheek). Other sites of the mouth, including the parotid gland, are rare for this disease. Canalicular adenoma is most likely to occur in older adults around 70 years of age. There is a predilection for gender with most cases being in females. Canalicular adenoma is characterized as a slow growing, painless swelling, whose diameter can be up to 2 cm. It can be normal or bluish in color. The appearance of this tumor microscopically is very distinct. There are cords of columnar or cuboidal epithelium, which have basophillic nuclei. Parallel rows of cords appear to form long canals. Frequently, there are large cystic spaces. There are no stromal alterations evident. Treatment usually ...
Classically these tumors show biphasic manifestation with admixture of varying amounts of polygonal salivary gland cells and spindle shaped myoepithelial cells. The underlying stroma could be mucoid / myxoid / cartilagenous / hyaline. Even though these tumors are not encapsulated but thickening of parotid fascia around the mass gives it an encapsulated appearance (pseudocapsule).. The main cause for this tumor is juxtapositioning of PLAG gene to the gene for beta catenin. This causes activation of catenin pathway leading on to inappropriate cell division.. ...

Introduction: Treatment of choice for pleomorphic adenoma of the hard palate is wide local resection of the tumor including the overlying mucosa and underlying periosteum. Most conventional methods for covering the resulting palatal wound are prosthetic devices. In this case, we examined the validity of grafting a polyglycolic acid sheet and fibrin glue over a mucosal defect of the palate with a bony surface, as a substitute for a surgical splint. Case Report: A 39-year-old male presented with a large, solid mass located on the right hard palate. Fine-needle aspiration cytology suggested pleomorphic adenoma. The patient underwent wide local resection of the lesion, and the mucosal defect was immediately covered with polyglycolic acid sheets, that were fixed with a fibrin glue spray. These sheets were tightly placed and remained in the wound, which led to complete epithelialization of the wound surface. Conclusion: Grafting the polyglycolic acid sheet with fibrin glue fixation is a useful substitute for
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective when given together with chemotherapy or alone after surgery in treating salivary gland tumors.. PURPOSE: This randomized phase II/III trial is studying radiation therapy with or without chemotherapy to see how well it works in treating patients with high-risk malignant salivary gland tumors that have been removed by surgery. ...

The success rate of these procedures is very much dependent on the ability of the operator and the equipment used. The equipment has to have the capabilities to operate at very low power because the syringoma are not very thick and a powerful ablation could result in damage to the dermis and therefore permanent scarring.. The method used to remove the syringoma by Electrodesiccation is very simple and this involves simply ablating the lesions from the top and level it off with the rest of the surrounding skin. However since the syringoma reside inside the dermis as well, in order to minimise recurrence it is advisable to ablate them deeper inside the dermis. This is because it has been reported that most of the recurrence of syringoma is due to the fact that simply leveling off the syringoma with the surrounding skin is not sufficient to remove them completely and they will regrow soon after healing. A couple of weeks after the cosmetic procedure.. ...

TY - JOUR. T1 - Loss of heterozygosity and microsatellite alterations in p53 and RB genes in adenoid cystic carcinoma of the salivary glands. AU - Yamamoto, Yuzo. AU - Virmani, Arvind K.. AU - Wistuba, Ignacio I.. AU - McIntire, Donald. AU - Vuitch, Frank. AU - Albores-Saavedra, Jorge. AU - Gazdar, Adi F.. PY - 1996/1/1. Y1 - 1996/1/1. N2 - Adenoid cystic carcinomas (ACC) constitute approximately 20% of malignant salivary gland tumors. Several histological types of ACC are recognized and may coexist in a single tumor. The authors divided ACC into lower grade (tubular and cribriform subtypes) and higher grade (trabecular and solid) subtypes. A preliminary analysis of 10 ACCs showed a relatively high incidence of loss of heterozygosity (LOH) at the p53 and RB genes and low or absent K-ras mutations and LOH at chromosomal loci 3p, 5q, 8p, and 9p. From 21 tumors, the authors carefully microdissected and analyzed 36 subtype foci. Three interrelated pieces of evidence indicate that the relatively poor ...
A 32 year old woman presented with a large swelling in the left parotid area. Past history revealed that the patient had undergone enucleation of a left parotid mass at 9 years of age that showed calcular atrophy with sialadenitis, and superficial parotidectomy of a recurrent mass at 15 years of age that was considered pleomorphic adenoma. A magnetic resonance imaging showed an 11.8 x 6 cm mass in the left parotid area extending into the infratemporal fossa and the parapharyngeal space. The mass was removed by total parotidectomy. ...

Dermatol Sinica 4: 1-6, 1986. Seven cases of chondroid syringoma of the skin collected from 1983 to 1985 are reported. The patients ranged from 26 to 58 years of age and 4 of them were male. They presented as asymptomatic solitary dermal or subcutaneous nodule. The sites of predilection were the nose (4 cases) and the chin (2 cases); one unusual case occurred on the foot. The tumors were well circumscribed and composed of epithelial cells forming solid nests or glandular structures in a chondroid or myxoid stroma. Squamous metaplasia was occasionally observed. Except one case with 3 recurrences, the others did not recur. A complete surgical excision is usually adequate. ...

Syringoma: A benign tumor of the sweat glands which is usually multiple and results from malformation of sweat ducts. It is uncommon and more common in females than in males. It is most likely to appear at adolescence, and further lesions may develop during adult life. It does not appear to be hereditary. (Rook et al., Textbook of Dermatology, 4th ed, pp2407-8)
Syringoma on the penis can be quite distressing and worrisome for most individuals. People often fear the lesion for being sexually transmitted such as condyloma accuminata.
We present a case of cutaneous leiomyomas (CL) arising in a pleomorphic adenoma (PA) of the parotid gland. PA and CL are benign tumors arising from the parotid gland and the erector pilli muscle, respectively. They both have a benign clinical course and in most cases leiomyomas are multiple in nature. PAs of the parotid are the most frequent benign tumors of the major salivary glands. To our knowledge this is the first case of PA with CL.
We show that TRH mRNA is expressed in human fetal and adult pancreata, and that TRHR mRNA is expressed in fetal human pancreas but not in adult human pancreas. Comparative evaluation between two immunoenzymatic techniques (FAST and cialis reviews by men Phadezym) and the Phadebas RAST in food allergy. Implications for community interventions and directions for future research are discussed..

In a sense, though I tend to do all right with them, I truly hate the whole multiple choice approach to medicine. My diagnostic capability is not based on whether I can recognize a tyrosine crystal in a single poorly 2D image from a pleomorphic adenoma slide. What is my triage method? What tests do I run on a scant specimen? If I have a malignancy of unknown origin in an elderly womans pleural fluid, I dont need to have the second leading cause of malignant pleural effusions memorized and then try to figure out whether the questions as written ten years ago or ten months ago and whether a few things switched places on the charts. I need a basic, streamlined workup that is most likely to lead me to the correct diagnosis for the least money and waste of specimen. I need to know when to ask for help, when to ask for flow cytometry, and when to get a cell block and what stains to order on the cell block, and when to stop throwing money and time down the drain and call the clinician to ask for ...

This lesion is described as a soft tissue enlargement. Reactive soft tissue enlargements can be excluded from differential diagnosis because the lesion has been present for several years and is progressively enlarging. Also, the lesion is not painful, except for occasional soreness associated with the denture.. Within the category of tumors, malignant tumors can be excluded because the lesion is very slowly growing and essentially asymptomatic. Soft tissue cysts are eliminated because they are fluid filled and have “hydraulic†properties, meaning that they are compressible and expand in all directions uniformly. Cysts do not have a surface with a depression or fissure.. From the category of benign tumors, epithelial lesions and salivary gland tumors can be excluded. Epithelial lesions can be excluded because these have a white, rough surface. Salivary gland tumors can be excluded because the lesion appears to be arising from the alveolar ridge mucosa. Salivary gland tumors may arise ...
Most salivary gland tumors are benign and occur in parotid gland. The most common sign of a salivary gland tumor is a painless mass.
Greetings to the general public, i want to tell about how i was cured of HERPES SIMPLEX VIRUS disease by a Dr Destiny . I was browsing through the Internet searching for remedy on HERPES and i saw comment of people talking about how Doctor Destiny cured them.

Pri moškem v 72 letih je prišlo do adenoma prostate. Obrnil se je k zdravniku, ko je bila bolezen že v zanemarjeni obliki, brez katetra pa ni bilo mogoče izprazniti mehurja. Takoj je ponudil operacijo za odstranitev adenoma, se je strinjal, odšel v bolnišnico, a ko sem videl post-kirurške bolnike, prestrašeni, izkazalo, da je z operacijo in je bil zaključen domov s katetrom. Po nasvetu urologu začel zdravljenje adenoma folk pravna sredstva: prvi dan posta mora jesti 0,5 skodelice orehov, v drugem - pol skodelice sončničnih semen, tretji dan od povprečja žarnice. Nadaljevati to zdravljenje prostate za tri mesece.. Moški je to zdravilo uporabljal in adenoma je izginila, a ker je imel nezdrav način življenja, se je nekaj let kasneje ponovno pojavil. Potem se je odločil, da bi adenoma zdravil z magnetom. Kupil je biokorrektorja iz podjetja Nevoton, vendar je bil učinek zdravljenja majhen. Potem je po mnenju zdravnika moški večkrat vzel magnet - od zvočnika radia. Poleg adenomom ...
