Malignant mixed Mullerian tumor of the uterine corpus with alpha-fetoprotein-producing hepatoid adenocarcinoma component.

OBJECTIVES

Hepatoid adenocarcinoma is a rare tumor and has the histological coexistence of well-differentiated adenocarcinoma and nests of hepatoid cells with immunoreactivity for alpha-fetoprotein (AFP). A case of hepatoid adenocarcinoma in malignant mixed Mullerian tumor of the uterus is presented with a review of the literature.

CASE: The patient is a 63-year-old woman who complained of abnormal genital bleeding. Serum AFP concentration was 5060 ng/ml. Histologically, the tumor was composed of endometrioid adenocarcinoma, neoplastic hepatoid cells, and sarcoma component including leiomyosarcoma and rhabdomyosarcoma. After operation followed by six courses of platinum-based chemotherapy, serum levels of AFP dropped into normal range.

CONCLUSIONS

This is, to our knowledge, the first report of malignant mixed Mullerian tumor of the uterus with an AFP-producing hepatoid adenocarcinoma component.
