A case of pulmonary type of ovarian small cell carcinoma.

Small cell carcinoma is a rare form of ovarian cancer with a poor prognosis. It is divided into two types, the hypercalcemic and the pulmonary type, of which the latter is extremely rare. A 49-year-old woman presented with an acute abdomen and was suspected to have torsion of a left ovarian tumor, which was followed up with an emergency operation. Postoperative pathological examination gave a diagnosis of the pulmonary type of ovarian small cell carcinoma. Six courses of paclitaxel and carboplatin therapy were given as adjuvant chemotherapy. The patient has survived for 36 months without recurrence. Here we present an extremely rare patient with the pulmonary type of ovarian small cell carcinoma.
