Ovarian endometrioid carcinoma resembling sex cord-stromal tumor (ECSCSs) is rare.
We present a rare case of primary ECSCSs in the left ovary. A 39-year-old female patient had persistent dull pain in the lower abdomen for more than 1 mo, and she was initially diagnosed with pelvic inflammatory disease at a hospital. The patient received transabdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymph node dissection at our hospital and finally diagnosed with ECSCSs. After the operation, the patient received eight courses of cisplatinum + etoposide + bleomycin chemotherapy treatment and no evidence of tumor recurrence or metastasis was found in a 2-year follow-up period.
Ovarian endometrioid carcinoma is similar to the ovary sex cord-stromal tumor, especially when the cord-like structure is obvious. The clinical diagnosis for this tumor is difficult before surgery and pathology examination. The necessary immunohistochemical markers are of positive significance for assisting diagnosis and differential diagnosis.
Core tip: In the clinicopathological diagnosis, if ovarian tumor has the morphology of sex cord-stromal tumor, clinicians should be aware of the possibility of endometrioid carcinoma resembling sex cord-stromal tumor. Extensive and comprehensive sampling of specimens can often find focal areas of classical endometrioid carcinoma. The necessary immunohistochemical markers are of positive significance for assisting diagnosis and differential diagnosis.
