Small-cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare and aggressive type of ovarian cancer. It generally presents in younger patients, is diagnosed at an advanced stage, and is associated with a dismal prognosis. Due to its rarity and morphologic similarity to more common ovarian tumors, diagnosis may be a challenge. A high index of suspicion followed by appropriate immunohistochemistry stains performed by an expert pathologist is essential to diagnosis. Two cases of SCCOHT are presented: 21 years old with rapidly progressive Stage IIIA1i disease who underwent surgery and succumbed to the illness after 3 months before adjuvant treatment could be given, and a 49 years old with Stage IIIB disease with tumor progression who is on adjuvant chemotherapy and apparently well, 21 months after her first symptoms appeared. Related literature is presented and compared to the features of the index cases. Diagnosis and treatment options are also discussed briefly.
