Question:

MP/H Rules/Histology--Colon: What histology would be coded when the right colon demonstrates a combined adenocarcinoma and high grade small cell neuroendocrine carcinoma [forming the dominant component] arising in a villotubular adenoma and the liver biopsy demonstrates metastatic high grade small cell neuroendocrine carcinoma?

Discussion:

Answer:

For cases diagnosed 2007 or later, start with rule H1 in the Single Tumor module. Stop at rule H4. Assign code 8263 [adenocarcinoma in tubulovillous adenoma].

Stop at the first rule that applies. Code histology based on a specimen from the primary site whenever available.
