Malignant giant cell tumor of the uterus. A clinico-pathologic, light- and electron-microscopic study of a case.

Abstract

A clinico-pathologic study of a 69-year-old woman with a malignant giant cell tumor of the uterus compatible with malignant giant tumor of soft tissues is presented. The diagnosis was based mainly on light- and electron-microscopic findings, including the demonstration of phagocytic activity of the neoplastic cells. The tumor metastasized to the lung and the patient died a short time after clinical onset. The classification of uterine sarcomas and the differential diagnosis are briefly discussed.
