Alpha-fetoprotein-producing serous carcinoma of the uterus metastasizing to the ovaries, mimicking primary ovarian yolk sac tumor: a case report and review of the literature.
In the uterus, most alpha-fetoprotein (AFP) producing neoplasms belong to the categories of malignant mixed muellerian tumor, hepatoid carcinoma, and yolk sac tumor. We describe the case of a 44-year-old woman who presented with vaginal bleeding, pelvic mass, and preoperative elevated AFP serum level, clinically suggestive of a primary ovarian yolk sac tumor. However, histological examination revealed a uterine AFP-producing papillary serous carcinoma, which has metastasized to the ovaries. Upon review of the literature on primary endometrial neoplasms with AFP production, 2 categories with possibly different histogenesis and biological behavior become evident: the primary yolk sac tumor of the uterus in young patients (range, 24-49 years; mean, 34 years) and the common high grade endometrial carcinoma with yolk sac dedifferentiation or aberrant AFP production in elderly patients (range, 55-69 years; mean, 63.7 years). In addition to being only the second case of uterine AFP-producing papillary serous carcinoma, this case is unusual for its clinical and radiological presentation as well as the relatively young age of the patient.
