Small Cell Carcinoma of the Ovary (SCCO)
About Small Cell Carcinoma of the Ovary (SCCO)
Small cell carcinoma of the ovary (SCCO) is a rare, highly malignant tumor that affects mainly young women, with a median age at diagnosis of 23 years old. It is not certain whether the cells in SCCO are from ovarian epithelial cells, sex-cord stromal cells or germ cells.
The subtypes of SCCO include pulmonary, neuro-endocrine and hypercalcemic. SCCO accounts for 0.1 percent of ovarian cancer cases. Approximately two-thirds of patients with SCCO have hypercalcemia. The symptoms are the same as other types of ovarian cancer.
