Ovarian small cell carcinoma of the hypercalcemic type, abbreviated OSSCHT, is a rare malignant ovarian tumour.

Small cell carcinoma, hypercalcemic type, and small cell carcinoma of the ovary, hypercalcemic type redirect here.

A proposed name of the entity is malignant rhabdoid tumour of the ovary, abbreviated MRTO.[1]

General

  • Hypercalcemia.[2]
  • Very rare.
  • Most common undifferentiated ovarian malignancy in individuals less than 40 years old.[3]
  • Associated with SMARCA4 mutations - may be familial.[3]

Microscopic

Features:[2]

  • Small cell carcinoma.
  • Follicle-like spaces.
