Uterine Müllerian adenosarcoma with psammoma bodies: cytologic, histologic and ultrastructural studies of a case.

Epithelial cells associated with psammoma bodies and undifferentiated sarcomatous tumor cells were found in peritoneal washings obtained during laparotomy for removal of metastatic lesions from a uterine stromal sarcoma. Histologic studies of the primary and recurrent tumors showed characteristics of Müllerian adenosarcoma. The cytologic, histologic and ultrastructural features are described.
