Hepatic angiosarcoma developing in an infantile hemangioendothelioma: A rare case report.

Angiosarcomas are rare tumors that predominantly affect adults. Hepatic angiosarcoma in a child is extremely rare and associated with a poor prognosis. Herein, we report the pathologic features of a hepatic angiosarcoma developing in a 31/2-year-old child who had been earlier diagnosed and was being treated for hepatic hemangioendothelioma.

Juvenile psammomatoid ossifying fibroma of maxillary sinus: case report with review of literature.

Juvenile psammomatoid ossifying fibroma is a rare benign fibro-osseous tumor of the gnathic and extragnathic craniofacial bones, particularly the periorbital, frontal and ethmoid bones. It is slowly progressive with aggressive local growth, invasion and destruction of the surrounding tissue, bone erosion and recurrence after surgical excision. It is distinguished from the other fibro-osseous lesions by its age of onset, clinical presentation and aggressive behavior.

Hepatic and adrenal hemangioendothelioma-a case report.

Haemangioendothelioma (HE) liver is a mesenchymal vascular tumour, intermediate between a haemangioma and an angiosarcoma. It has a variable clinical course, is a low grade malignancy and is associated with long-term survival. It has a characteristic histologic appearance. Immunohistochemical studies have shown that the neoplastic cells in HE are of endothelial derivation. These are essential to distinguish HE from metastatic carcinoma and primary epithelial liver tumour. We report a case of a 36-year-old male with HE of the liver with adrenal involvement, probably metastatic, with tuberculosis as an incidental finding. To our knowledge this is the first such case reported in literature. The confirmation of diagnosis was done by immunohistochemical study.

Intraventricular hydatid cyst in a child.

Hydatid disease is caused by the infestation of the larvae of tapeworms of the genus Echinococcus. The definitive hosts of Echinococcus are various carnivores, the common being the dog. All mammals (more often sheep and cattle) are intermediate hosts. Humans get infected through the feco-oral route by ingestion of food or milk contaminated by dog feces containing ova of the parasite or by direct contact with dogs. The most common sites of infestation are the liver (75%) and lungs (15%). Various authors state a frequency of hydatidosis of the brain ranging between only 0.2-4% of cases. [1],[2],[3] The prognosis following surgical intervention is good, especially in pediatric age. [2],[3] Hence early diagnosis of this condition is crucial. We report a rare case of a child with a large intraventricular hydatid cyst that had an excellent recovery following surgery.
