International Ophthalmology Clinics, 1982
AbstractHemangiopericytoma is a rare soft tissue tumor with unpredictable biological behavior and with a high local recurrence rate. Wide surgical excision of all lesions, whenever feasible, should be the treatment of choice.

Hemangiopericytomas of the Spine
Neurosurgery, 1982Abstract Four cases of hemangiopericytoma of the spine are reported. These are rare tumors that arise from the pericytes. Due to their invasive nature and marked vascularity, a detailed radiological work-up including computed tomography and spinal angiography should be obtained before a direct surgical attack is performed.

Hemangiopericytoma of the esophagus
Human Pathology, 1981A case of hemangiopericytoma arising in the esophagus is described. The light microscopic features were typical, and ultrastructural examination confirmed the presence of pericyte-like cells and excluded smooth muscle and fibroblastic differentiation.

Urology, 1982
Abstract Hemangiopericytoma of the kidney is extremely rare. A case of hemangiopericytoma of the right kidney with extensive vena caval tumor thrombus is reported. The typical hemangiopericytic pattern by light microscopy and the ultrastructural finding of pericyte-like cells were the basis for making this diagnosis.

The American Journal of Surgical Pathology, 1982
Hemangiopericytoma primary in bone is a rare tumor. A review of 15 cases (five from the Mayo Clinic files and 10 from the consultation files) revealed that all tumors were unifocal and that the most common location was the pelvis (three lesions in the sacrum and two in the ischium).

Hemangiopericytomas of the uterus
American Journal of Obstetrics and Gynecology, 1970Hemangiopericytomas are "cellular" tumors found in almost every site or organ in the body. Originally thought to be relatively benign, more recent data indicate that they have a fairly high degree of malignancy. Only a few have been recognized in the uterus. The present report includes 6 previously reported and 7 additional instances of this tumor.
