==Overview==
The exact pathogenesis of sexcord/ stromal ovarian tumors is not fully understood. Mutations mainly involving FOXL2, DICER1, STK11 are involved. They are associated with ollier disease and maffucci syndrome.The microscopic pathology varies with the individual subtype of sexcord stromal ovarian tumors.

They are associated with [[ollier disease]] and [[Maffucci's syndrome|maffucci syndrome]].The [[microscopic]] [[pathology]] varies with the individual subtype of sexcord stromal ovarian tumors.

Overview

The exact pathogenesis of sexcord/ stromal ovarian tumors is not fully understood. Mutations mainly involving FOXL2, DICER1, STK11 are involved. They are associated with ollier disease and maffucci syndrome.The microscopic pathology varies with the individual subtype of sexcord stromal ovarian tumors.
