Abstract

We report the clinical and pathological features, including the immunohistochemical and electron microscopic findings, of a case of hypercalcemic type, large cell variant, ovarian small cell carcinoma. A 44-year-old woman complained of abdominal pain and dysmenorrhea. A mass on the left ovary was detected by computer tomographic scan. A total hysterectomy with bilateral salpingo-oophorectomy was done. Histologically, the tumor was predominantly composed of large cells with abundant eosinophilic cytoplasm and prominent nucleoli. Mucin-containing cells and myxoid stroma were also present. Typical follicle-like spaces with lined by small, closely packed epithelial cells with scanty cytoplasm were occasionally seen. No dense core granules were identified on electron microscopic examination.
