hemangiopericytoma

Antibodies to CD99 are used in diagnostic immunohistochemistry to distinguish Ewing's sarcoma from other tumours of similar histological appearance, as well as for the identification of thymic tumours, and of spindle cell tumours, such as synovial sarcoma, haemangiopericytoma, and meningioma.

Hemangiopericytoma in older children and young adults.

Well-differentiated or infantile (patient age 4 years or younger) hemangiopericytoma.

In 2001, McMillan was diagnosed with hemangiopericytoma, a rare brain tumour.

A hemangiopericytoma usually forms in the dura mater.

If an infant or young child has fibrosarcoma or hemangiopericytoma, treatment will be surgery whenever possible.

Hemangiopericytoma.

Examples include hemangioma and hemangiopericytoma.

Malignant hemangiopericytoma.

Hemangiopericytoma is a rare vascular neoplasm, or abnormal growth, that may either be benign or malignant.

Hemangiopericytoma is caused by the excessive layering of sheets of pericytes around improperly formed blood vessels.

Basrur lived in Scarborough, but moved to Kitchener, where she underwent treatment for hemangiopericytoma, from which she eventually died on June 2, 2008.

Treatment of grade II and III meningioma and hemangiopericytoma may include the following:

A hemangiopericytoma is not a meningeal tumor but is treated like a grade II or III meningioma.

Post-operatively, presence of renin granules in pathology specimens differentiates this tumor from renal hemangiopericytoma and other renal tumors.

Hypoglycemia and hypophosphatemic rickets have been reported in cases of hemangiopericytoma, whereas hyperglycemia has been noted in patients with fibrosarcoma of the lung.

A benign mesenchymal or mixed connective tissue tumor (usually phosphaturic mesenchymal tumor and hemangiopericytoma) are the commonest associated tumors.

Hemangiopericytoma with t(7;12)(p22;q13)-translocations is a rare affliction, in which a translocational mutation causes the fusion of the ACTB gene over GLI1 in Chromosome 12.

Anaplastic meningioma and hemangiopericytoma are difficult to distinguish even by pathological means as they look similar, especially if the first occurrence is a meningeal tumor, and both tumors occur in the same places (same types of tissue).

Infantile hemangiopericytoma (also known as "Congenital hemangiopericytoma") is a cutaneous condition characterized by single or multiple dermal and subcutaneous nodules that may be alarmingly large at birth or grow rapidly.

The variety of different tumors that fall under the category of soft tissue sarcomas includes fibrosarcoma, hemangiopericytoma, liposarcoma, rhabdomyosarcoma, leiomyosarcoma, malignant fibrous histiocytoma, malignant nerve sheath tumors, myxosarcoma, myxofibrosarcoma, mesenchymoma, and spindle cell tumor.
