Definition

An stromal tumor characterized by the presence of lipid-rich neoplastic spindle cells. In females, uterine bleeding is the most common symptom. A minority of post-menopausal women with thecoma have an associated endometrial adenocarcinoma or rarely a malignant mixed mullerian tumor or endometrial stromal sarcoma. Rare cases with nuclear atypia and mitotic activity may metastasize. Metastases have not been reported.
