Familial small cell carcinoma of the ovary

Abstract

Ovarian tumors have a low incidence in childhood, accounting for 1% of malignancies within the ages of 0-17 years. Small cell carcinoma of the ovary is a rare histology and historically has a poor prognosis. We report a case of an 11-year-old female diagnosed with small cell carcinoma of the ovary and hypercalcemia (SCCOHT). There was a strong family history of the disease, a reduction in the age of onset in the proband, and the absence of BRCA mutations. This case suggests the phenomenon of genetic anticipation in an ovarian cancer.
