Lymphoepithelioma-like carcinoma of the ovary: A case report and review of the literature
Lymphoepithelioma-like carcinoma is an undifferentiated carcinoma morphologically characterized by sheets of pleomorphic epithelioid cells with an intense lymphoid infiltrate. A 51-year-old woman presenting with low abdominal pain was found to have a right ovarian mass and enlarged pelvic, left para-aortic, and left supraclavicular lymph nodes. Based on a clinical diagnosis of right ovarian carcinoma with lymph node metastases, she received 9 cycles of chemotherapy, resulting in a reduction of her ovarian tumor, disappearance of the enlarged pelvic and para-aortic lymph nodes, and normalization of serum CA 125 level. The residual mass was removed surgically. The histology of the multinodular tumor resembled that of lymphoepithelioma of the nasopharynx and was observed in the right ovary. However, there was no viable tumor in either supraclavicular or para-aortic lymph nodes. Seven months after surgery, the patient has no evidence of disease. Lymphoepithelioma-like carcinoma appears to be rare in the female genital tract.
