title: Canine hemangiopericytoma: 23 cases (1967-1984).
abstract: The medical records of 23 histopathologically confirmed cases of canine hemangiopericytoma were reviewed. Ninety-one percent (21/23) of the dogs were 7 years old or older, and 70% (16/23) were female. Seventy-four percent (20/27) of the tumors developed on the extremities. Recurrence rates were 31% (5/16) with surgical excision only, and 60% (3/5) with surgical excision combined with radiotherapy. Tumor recurrence did not appear to be related to mitotic index. Metastasis was suspected in one of the dogs, but was not confirmed.
