Endometrioid tumors are a class of tumors that arise in the

ovarian tumors.[1]

Ovarian endometrioid tumors are part of the

tumor group of ovarian neoplasms
(10–20% of which are the endometrioid type).

. There is an association with
endometrial carcinoma (endometrial cancer
).

On gross pathological examination, the tumor is cystic and may be solid and some arise in cystic endometriosis. In 40% of cases, endometrioid tumors are found bilaterally.[3]

Endometrium

Endometrioid carcinoma can also arise in the endometrium.[4][5]

Grades 1 and 2 are considered "type 1" endometrial cancer, while grade 3 is considered "type 2".[6]

Molecular biology

Ovarian and endometrial endometrioid carcinomas have distinct

tumorigenesis.[9]
