Imagine that a seven-year-old girl develops a hormone-secreting ovarian tumor derived from granulosa cells. What signs of the disease would you expect?
What will be an ideal response?
Granulosa cells produce estrogen, so a tumor involving these cells would lead to highly elevated levels of estrogen. Estrogen would set in motion the development of secondary sex characteristics, such as breast enlargement, deposition of fat in characteristic places, development of axillary and pubic hair and apocrine sweat glands, along with accelerated skeletal growth.
