•DICER1 mutations play a significant role in gynecologic malignancy.•DICER1 may be involved in the sarcomagenesis of endometrial adenosarcoma.•The knowledge of a genetic mutation can help clarify a patient's medical history.

BACKGROUND Adenosarcomas are rare tumors usually derived from the endometrium. About 50 cases of adenosarcomas of the ovary have been reported. The relationship between adenosarcoma and CA125 has not been described. The authors present a case of adenosarcoma with elevated CA125 because of the unusual presentation of this pathology and also because elevation of the CA125 antigen has not been rep...

Cervical adenosarcomas are exceedingly infrequent tumors that occur most often in women of reproductive age. Adenosarcomas comprise benign epithelial elements and malignant stromal elements. The malignant stromal elements can either be homologous, such as fibroblasts or smooth muscle, or heterologous, like cartilage, striated muscle, or bone. We report a case of adenosarcoma of the cervix with ...

Endometriosis is ectopic presence of endometrial glands surrounded by endometrial stroma. Polypoidal endometriosis is a recently described entity which mimics neoplastic growth. Grossly and microscopically, polypoidal endometriosis can mimic benign and malignant tumors like adenofibroma, adenomyoma, low-grade stromal sarcoma, endometrial carcinoma and adenosarcoma. We report this case of polypo...
