Answer 33

All ages

Question 34

Sertoli-Leydig Cell Tumors

Answer 34

Sertoli cells form tubules and the Leydig cells contain Reinke crystal and can produce androgen which would cause virilization

Question 38

Pseudomyxoma peritonei

Answer 38

Abundant mucin in the peritoneum - "jelly belly" often due to a primary tumor of the appendix which spreads to ovaries
