Q

What are the three cell types in the ovary?

A

Surface epithelium, germ cells, sex cord stroma

2
Q

What is the most common type of ovarian tumor? Where is it derived from?

A

Surface Epithelial tumor (70% of cases). Derived from coelomic epithelium that lines the ovary.

3
Q

What is the embryological origin of the epithelial lining of the fallopian tubes , endometrium and endocervix?

A

Coelomic Epithelium

4
Q

What are the two most common types of surface epithelial tumors? What characteristic do they share?

A

Serous tumors which are full of watery fluid and mucinous tumors which are full of mucus like fluid. oth are cystic

5
Q

What are cystadenomas composed of? Which age group do they arise in?

A

Composed of single cyst with a simple flat lining. Most commonly arise in premenopausal women (30 - 40 years old)

Q

When and with what symptoms do surface tumors present? What is their prognosis and how do they spread?

A

Clinically present late with vague abdominal symptoms (pain and fullness) or signs of compression (urinary frequency). Poor prognosis. Epithelial carcinomas tend to spread locally, especially to the peritoneum.
