Inquiry Details
References:
WHO Class Breast Tumors. 2012, 4th Edition
Question:
Histology--Breast: Please confirm the morphology code for a diagnosis of "encapsulated papillary carcinoma" of the breast. Several articles on the internet lead me to believe it is the same as an intracystic carcinoma, code 8504/2 (our case shows no evidence of invasion).
Discussion:
Answer:
You are correct in coding 8504/2 for this case. Per the 4th Edition WHO Tumors of the Breast, encapsulated papillary carcinoma (EPC) of the breast is synonymous with intracystic or encysted papillary carcinoma. It is a variant of ductal carcinoma in situ (DCIS).
