A 2-year-old girl, with bifid epiglottis, imperforate anus, and mesoaxial and postaxial polysyndactyly (figure 1), first developed focal seizures at 3 months of age with subsequent progression to generalized seizures. Her epilepsy is well-controlled with carbamazepine and her development is normal. EEG was normal. MRI brain revealed hypothalamic hamartoma (figure 2). Targeted next-generation sequencing revealed a de novo pathogenic variant (c.2149C , T;p.Gln717*) in GLI3, confirming Pallister-Hall syndrome, which is inherited in an autosomal dominant pattern. Its primary feature is hypothalamic hamartoma, which can result in hypopituitarism and epilepsy (classically gelastic), which responds well to antiepileptic medications.1 ...

A hamartoma is a benign malformation of native tissue that may occur in any area of the body. Hamartoma of the tongue is a rare developmental lesion. We describe the case of a pendulant lingual hamartoma in a 2-day-old girl that had not been identified on prenatal ultrasonography. We also review the utility of prenatal imaging options, the role of preoperative imaging, the mechanical relationship between lingual hamartoma and cleft palate, the histopathology of this tumor, surgical treatment, and emergency airway management. ...

Pulmonary MGA with lack of bronchial relation is extremely unusual.4 Moreover, MGA of the peripheral lung with cartilage islands has not been reported.. The histologic findings of a benign mucous glandular proliferation mixed with cartilage/mesenchymal component suggest several possible scenarios. First, it is reasonable that MGA with myxoid stroma develops chondroid metaplasia, as occurs in other organs. The stroma of MGAs varies, and hyalinized sclerosis can be seen.2 However, no report describing myxoid stroma and cartilage islands in MGA could be found in the English literature.. We also considered coincidental combination of MGA and pulmonary hamartoma. There was a case report of a collision tumor of pulmonary hamartoma and a carcinoid.5 However, this was likely an extremely extraordinary situation, considering the rarity of mucus gland adenoma.. There have been two reported cases of salivary gland-type tumors developed in hamartoma; myoepithelioma and malignant mixed tumor.6 The ...

Folliculosebaceous cystic hamartoma (FSCH), first described by Kimura et al in 1991, is a rare cutaneous hamartoma composed of dilated folliculosebaceous units associated with mesenchymal elements. Some authors have presented evidence suggesting that this lesion is very closely related to trichofolliculoma.. Clinical presentation: Majority of lesions present as 0.5-1.5 cm papules or exophytic nodules. Lesions are usually rubbery to firm in consistency. Typically arise in adulthood but the giant variant appears to be congenital and enlarges during puberty. Site: Face or scalp, ear and upper back. ...

Vascular hamartomas are non-neoplastic developmental anomalies of vessels. Cases of cerebral vascular hamartomas have been previously reported in dogs and cats. A 4-week-old Freiberger foal had shown persistent problems with breathing and swallowing since birth, and bilateral laryngeal paralysis was diagnosed. The foal subsequently developed left sided facial nerve paralysis and a secondary corneal ulcer in the left eye. Necropsy revealed a pinkish mass in the obex region of the brain. The mass was further investigated by histology and immunohistochemistry. Histologically, the mass consisted of many thin-walled, blood-filled vascular structures of variable diameter involving the white matter of the obex. The lining cells were immunohistochemically positive for factor VIII (von Willebrand factor) interpreted as endothelial cells. The endothelial lining showed also variable immunoreactivity for smooth muscle actin and vimentin. Normal neural parenchyma labeled with antibodies directed against ...
Respiratory epithelial adenomatoid hamartoma (REAH) is a rare and nonneoplastic lesion of upper respiratory tract characterized by an abnormal mixture of tissues which are peculiar to the involved anatomic region. The most common site reported is nasal cavity and its nasopharyngeal origin is extremely rare. The lesion can be confused with a variety of benign and malignant entities. In this article, we report a 22-year-old female case of REAH of posterior nasopharyngeal wall. The clinical and radiological features of the lesion are discussed in the light of literature data. ...
BACKGROUND AND PURPOSE: Respiratory epithelial adenomatoid hamartoma is a benign glandular neoplasm of the sinonasal cavities, which presents in isolation (REAHi) or in the setting of an adjacent inflammatory process such as sinonasal polyps. It is frequently found in the olfactory clefts. CT features of the 2 clinical presentations have not been well defined. We present the CT findings of REAH, focusing on the degree of associated sinusitis and changes in the OCs. We hypothesized that widening of the OCs and associated severity of the sinusitis are diagnostic features of REAH, differentiating it from SNP. ...
The olfactory cleft is the specific site of development of many tumours (respiratory epithelial adenomatoid hamartoma, intestinal-type adenocarcinoma, neuroblastoma, inverted papilloma, glomangiopericytoma, etc.) and is also the site of CSF rhinorrhoea via the cribriform plate (cribri-rhinorrhoea). Olfactory cleft surgery must therefore be considered to be a specific type of surgery, complementary to ethmoidal labyrinth surgery and anterior skull base surgery. Olfactory cleft tumours can be resected according to five different surgical procedures: olfactory cleft mucosal resection, partial resection of the olfactory cleft, total resection of the olfactory cleft, unilateral endoscopic anterior skull base resection, and bilateral endoscopic anterior skull base resection ...
A hypothalamic hamartoma (HH) is a rare developmental malformation associated with seizures of varying semiology, including Gelastic seizures [1, 2, 3, 4]. The hamartoma is typically located on the ventral portion of the hypothalamus near the mammillary bodies [5]. The presence of a HH is linked with cognitive decline and behavioral issues, as well as the early onset of puberty [1, 5, 6]. Roughly half of all patients with HH have either focal or general cognitive deficits of varying severity (with some ultimately declining to the point of intellectual disability), and around one-third have behavioral difficulties including ADHD, violent outbursts, conduct disorder, and co-morbid psychiatric conditions [5, 7, 8]. The cognitive decline and behavioral disturbances observed in patients with HH are linked with both the size and location of the hamartoma, as well as seizure frequency [5]. As for treatment options, anti-epileptic drugs have poor efficacy in this population and a surgical approach (e.g. ...

Dacrystic seizures. Dacrystic seizures are rare, occurring with an estimated frequency of 0.13% in patients admitted for long-term video monitoring.1 Seizures are characterized by stereotyped crying and may encompass lacrimation, sobbing, or sad facial expression. They most commonly occur along with gelastic seizures and/or generalized tonic-clonic seizures. A hypothalamic hamartoma is usually the cause when patients have both dacrystic and gelastic seizures, whereas isolated dacrystic seizures are typically associated with mesial temporal sclerosis. The proposed pathophysiology is thought to be from excitation of neurons in the hypothalamus or secondary to a hypothalamic autonomic release phenomenon from disinhibited regulatory cortex. Dacrystic seizures are often medically refractory, with no guaranteed improvement after epilepsy surgery. ...

Lipofibromatous hamartoma, a rarely occurring nerve hamartoma, can present as an acrochordon, cutaneous cyst or other soft tissue tumor and is usually seen within the first three decades of life. The lesion presents as a slowly growing mass that is largely composed of fat and fibrous tissue with epineural and perineural proliferation. Although such tumors are rare, it is important for physicians to be aware of this disorder and recognize its signs because patients may present with what appears t ..................More ...
We aim to provide an up-to-date summary of infantile hepatic hemangioma (IHH) and its misnomers and to dialectically present the differential diagnosis of these rare entities of the liver. Eligible peer-reviewed articles on hepatic infantile hemangiomas, published between 2000 and 2015, were reviewed for this study. IHH is the most common hepatic vascular tumor in children. Once a liver mass is identified in an infant, the differential diagnosis ranges from vascular malformations to benign and malignant tumors including mesenchymal hamartoma, hepatoblastoma, metastatic neuroblastoma, so careful physical examination, imaging studies, and, if indicated, tumor markers and biopsy, are of pivotal importance to ascertain the correct diagnosis ...

title:Histopathological Study of 100 Cases of Vasculartumours. Author:Kapuriya Dharmesh P, Patel Prashant, Shah Amrish N. Keywords:Vascular tumors, Enzingers classification. Type:Original Article. Abstract:Introduction: Vascular tumors show a broad variety of morphological appearances and cilinical behavior, the lesions are ranging from benign hemangiomas to intermediate lesion, which are locally aggressive, to highly malignant angiosarcoma. There is also the grey zone between true neoplasia and hamartoma, which makes difficulty in histopathological assessment. It is also important to decide the degree of malignancy as it can strongly influence the choice of treatment and prognosis. Methodology: Hundred cases of vascular tumors received at the department of pathology, medical college and SSG hospital, Baroda have been studied with a view to carrying out a histopathological analysis. Results: mploying modified Enzingers classification (2001) the break up of 100 cases was as follows : 37 - ...

Central precocious puberty (CPP) is caused by premature activation of the hypothalamic-gonadal axis, and must be treated adequately. In particular, CPP that occurs at a relatively young age or in boys is likely to be caused by an organic lesion. Hypothalamic hamartoma (HH) is the most common organic cause of CPP. The present case report describes an 11-month-old female infant who presented with vaginal bleeding and rapidly progressive secondary sex characteristics from the age of 6 months. She was diagnosed with CPP following the detection of HH via magnetic resonance imaging. The infant girl was successfully treated with gonadotropin-releasing hormone agonist. After 6 months, her breast had regressed and clinical and radiological follow-up demonstrated stable findings with no evidence of tumor growth or secondary sexual characteristics until the fourth year after the initiation of treatment. This patient is the one of the youngest infants presenting with CPP and HH in Korea; treatment was successful
Tuber cinereum hamartoma (also known as hypothalamic hamartoma) is a benign tumor in which a disorganized collection of neurons and glia accumulate at the tuber cinereum of the hypothalamus on the floor of the third ventricle. It is a congenital malformation, included on the spectrum of gray matter heterotopias. Formation occurs during embryogenesis, typically between days 33 and 41 of gestation. Size of the tumor varies from one to three centimeters in diameter, with the mean being closer to the low end of this range. It is estimated to occur at a frequency of one in one million individuals. The classic presentation is gelastic or laughing epilepsy, a disorder characterized by spells of involuntary laughter with interval irritability and depressed mood. The tumor can be associated with other seizure types as well as precocious puberty and behavioral disorders. Gelastic epilepsy has been more classically associated with sessile lesions and precocious puberty reported with pedunculated ...

He was examined in our hospital because of a chief complaint of bloody stool on October 2, 1996. Contrast roentgenography of the small intestine revealed a tumor in the jejunum. One week later, abdominal ultrasonography and CT showed target-shaped thickening of the small intestine suggesting intussusception of the small intestine. However, there were no symptoms in the abdomen. Reexamination by contrast roentgenography of the small intestine showed good passage and no intussusception of the small intestine. He was diagnosed as having intussusception caused by a tumor in the ...
A fairly quite rare case of osseous tumor arising from the Eustachian tube (ET) is described. A 56-year-old man presented with a smooth bulky mass in the nasopharynx and secretory otitis media in the right ear. Computed tomography and magnetic resonance imaging indicated a solid tumor-like region occupying the nasopharynx with apparent extension to the right ET. Transnasal endoscopic surgery demonstrated that the tumor had originated from the ET, and the tumor was partially removed in the area where it had expanded into the nasopharynx. The pathological diagnosis was an osseous hamartoma consisting of bony tissue, fat cells and fibroblasts. To our knowledge, this is the first reported case of osseous hamartoma arising from the ET in the world literature. The patient presented symptoms of nasal obstruction and unilateral aural fullness. Reduction surgery and tympanostomy tube insertion were useful for accurate diagnosis and resolution of the symptoms ...

To the Editor:. The tailgut cyst is believed to be a vestigial remnant of the tailgut, which is a primitive gut temporarily present at the caudal portion of the embryo. The cyst is histologically characterized by the presence of a multilocular cyst lined by various types of epithelia, including ciliated columnar, mucin-secreting columnar, transitional, and squamous epithelia (1,2). Transitional epithelium is present at tissue developing from the cloacal membrane, such as the urinary bladder and anorectal junction. Presence of transitional epithelium in the cyst may indicate participation of the cloaca in its development. The cyst contains neither villi nor crypts as seen in normal bowels. Smooth muscle may be present, but a myoenteric plexus and serosa are absent (1). It is usually located in the retrorectal or presacral space. Here we report a rare case of a tailgut cyst where the cyst presented as a subcutaneous tumor in the coccygeal region.. A 26-year-old Japanese woman with no significant ...

Peutz-Jeghers syndrome was diagnosed in a 51-year-old woman presenting with iron deficiency anaemia. Upper gastrointestinal endoscopy and colonoscopy revealed several hamartomatous polyps in the stomach, duodenum and colon, which were removed. At a combined surgical-endoscopic procedure, 42 hamartomatous polyps were removed from the small intestine by snare polypectomy. This enteroscopic procedure reduces symptoms, may protect against future intestinal obstructive episodes and their associated surgery, and may reduce the risk of developing gastrointestinal malignancy.. ...
