Although 75% of intussusceptions occur within the first two years of life, they can also develop in teenage years. This is a case report of a 13-year old boy with an ileocolorectal intussusception from a large caecal hamartoma (10 x 6 x 2 cm3) adjacent to the ileocaecal valve. Partial resection of the ascending colon and terminal ileum was performed, and the pathology of the resected mass revea...

We report a case of a mesenchymal hamartoma of the liver in a two-year-old boy. He presented to the emergency room with abdominal distention and vomiting. Abdominal ultrasound and computed tomography were performed and revealed a large, intra-peritoneal lesion, with thick wall, multiple cysts of variable size and solid septa. The lesion was surgically resected. Pathological examination revealed...

Chondro-osseous respiratory epithelial adenomatoid hamartoma is a rare hamartomatous lesion of the nasal cavity, with only five cases reported in the literature to date. We report the case of a 3-year-old boy who presented with nasal obstruction and a mass in the left nasal cavity. The mass was completely resected on endoscopy. On microscopy, hamartomatous proliferation of respiratory-type glan...

PURPOSE To present a case of small hypothalamic hamartoma (HH) causing gelastic seizures and treated with stereotactic radiofrequency thermocoagulation. CASE REPORT A 22-year-old man presented with intractable gelastic seizures and focal seizures refractory to medical treatment. Magnetic resonance imaging showed a 6 mm x 6 mm x 7 mm sessile intraventricular HH. Under local anesthesia, four in...

BACKGROUND Fibrous hamartoma is the key pathology of congenital pseudarthrosis of the tibia (CPT), which was shown to have low osteogenicity and high osteoclastogenicity. This study further investigated the mechanism of impaired osteoblastic differentiation of fibrous hamartoma cells. METHODS Fibroblast-like cells were obtained from enzymatically dissociated fibrous hamartomas of 11 patients ...

luteal hidradenitis suppurativa (HS) is an acute, subacute, or chronic infection that affects the sudoriparous, apocrine, eccrine, or pilosebaceous apparatus of the affected area. Although its pathophysiology is poorly understood, it is generally believed that obstruction of the apocrine pores results in glandular dilatation and bacterial superinfection, with subsequent gland rupture disseminat...

Apocrine glands are the major type of sweat gland in dogs, and distribution of eccrine sweat glands is limited to footpad (Goldschmidt and Shofer, 1992). Apocrine sweat gland tumors are rather common in dogs and tend to occur on the head, neck and limbs. The Golden Retriever is a breed that shows a predisposition to such tumors (Kalaher et al., 1990). The tumor was greatly resembles its human c...

Apocrine differentiation was an incidental finding in an ovarian cyst. This is considered to be a further example of Müllerian metaplasia that has not been described before and which, theoretically, could occur in any organ of Müllerian derivation (ovary, uterus, cervix or fallopian tube). It is suggested that sites of such metaplasia could in turn be the origin of primary apocrine carcinoma in...

Angio eccrine hamartoma (EAH) is a rare, benign tumoral lesion composed of glands and vascular structures in the mid dermis. We report on two observations Dakar. Observation 1: A four-month-old infant was seen for an erythematous plaque, rounded, with smooth surface, asymptomatic, localized to right thigh, evolving three months. The clinical appearance suggested spitz tumour. Cutaneous histolog...

Fibrous hamartoma of infancy is a rare, benign soft tissue tumor that typically occurs within the first two years life. The histogenesis unclear. It most commonly found in axilla, shoulder, inguinal region, and chest wall usually solitary malformation located subcutaneous or reticular dermis. Local recurrence uncommon treatment largely successful by local excision. clinical course prognosis exc...
