Discussion:

Example

Multicentric infiltrating lobular carcinoma of left breast treated with MRM. Microscopic summary: Blood/lymphatic Vessel Invasion: present. Path final diagnosis: Angiolymphatic invasion present, including dermal lymphatic invasion in nipple. Micro: There is angiolymphatic invasion, including dermal capillary invasion identified in sections of the nipple.

The path report describes multiple breast tumors, none of which is located adjacent to the nipple.

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Assign CS Extension code 20 [Invasion of subcutaneous tissue...] based on the final diagnosis on the path report. There is "dermal lymphatic invasion in nipple." In this case, the stage will be determined by the tumor size.
