Question:

MP/H Rules/Histology--Breast: How is histology coded for a breast primary with a final diagnosis of "infiltrating duct carcinoma with apocrine features"? See Discussion.

Discussion:

I & R has conflicting answers: #25719 (dated 3/17/2008) says per rule H12 this is 8401/3 but #23347 (dated 8/12/07) says per rule H16, this is 8523/3.

Answer:

For cases diagnosed 2007 or later, assign histology code 8401/3 [apocrine adenocarcinoma] according to rule H12. Apocrine is a type of duct carcinoma, see table 1. Code 8401 should be listed in Rule H12. Apocrine should be removed from table 3.

These corrections will appear in the revised version of the rules.
