Question:

Primary Site: How do we code site when endometrioid carcinoma arises in "endometriosis"?

Discussion:

Answer:

Code the Primary Site to where the endometriosis implanted, which may or may not be the endometrium. Endometrioid carcinoma can arise in the ovary, endometrium and other internal genital sites. The site/histology edit for endometrioid and ovary has been removed from the SEER edit set.
