Malignant hemangiopericytoma of the ovary

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.
