Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT) is a rare and aggressive cancer which mainly occurs in adolescents and young women. It represents less than 0.01% of all ovarian malignancies , with fewer than 500 cases reported to date

Approximately two thirds of patients with ovarian small cell carcinoma have hypercalcemia.  Hypercalcemia is a condition in which the calcium level in your blood is above normal. The clinical management of SCCOHT has varied widely. Outcome remains poor, with estimated long-term survival reported as 33% in stage I disease, and 10–20% overall.
