Malignant Hemangiopericytoma of the Ovary

Abstract

Tumors originating from the blood vessels seldom occur in the ovaries, and primary hemangiopericytoma localized to the ovaries has not previously been described. In the case reported here a bilateral ovarian tumor was found, with one metastasis to the terminal ileum. It was not possible to perform a radical operation, and the patient was after-treated with external irradiation therapy and chemotherapy. For 9 1/2 months the tumor receded, whereafter it appeared to be stationary for 13 months, to the death of the patient. At autopsy the tumor was in evident regression and there were no signs of metastases.

Haemangiopericytoma ‐ Queensland Radium Institute Experience and a Review of the Literature

“…Haemangiopericytoma (HPC) is a rare histological sub-type of soft tissue sarcoma, accounting for < 1 % of all sarcomas of vascular origin (12). The cell of origin is the pricyte, and the tumour was first so classified by Stout in 1942. The majority of HPC are found in the extremities (45-50%), the retroperitoneum and pelvis (20-24.5%), or head and neck region (16%) (9,21, 2) although their existence has been reported in most parts of the body including the gall bladder (1 l), spleen (16), ovary (20), lacrimal sac (3, and nasal cavity (15,7).…”

A case of metastatic malignant hemangiopericytoma of the ovary: Recurrence after a period of 17 years from intracranial tumor

“…However, the occurrence of this tumor in the ovary is extremely rare. To our knowledge, two cases of primary hemangiopericytoma of the ovaries have been described (9,10) . One metastatic ovarian tumor from a malignant hemangiopericytoma of the gallbladder was also reported (11) , in which case the gallbladder and right ovary were replaced by the tumors on exploratory laparotomy.…”
