title: Intragluteal spindle cell hemangioendothelioma. An unusual presentation of a recently described vascular neoplasm.
abstract: A 40-year-old woman noted a large tumor mass in the left buttock that, on microscopic examination, proved to be a recently described, relatively uncommon spindle cell hemangioendothelioma. This particular neoplasm, which has some features of Kaposi's sarcoma, seems not to have been reported previously in a deep, intramuscular location.
