Question
MP/H Rules/Multiple primaries--Other sites: A patient has a total colectomy showing neuroendocrine carcinoma of the rectosigmoid junction, as well as a separate adenocarcinoma arising in a villous adenoma, also arising in the rectosigmoid junction. Is this a single primary per rule M17 (a frank adenocarcinoma and an adenocarcinoma in a a polyp) or per rule M16 (adenocarcinoma and a more specific adenocarcinoma) or is this 2 primaries?

Discussion


Answer
Abstract two primaries per Rule M17. Neuroendocrine carcinoma is 8246 and adenoca arising in a villous adenoma is 8261. Rule M13 does not apply to neuroendocrine carcinoma. M16 does not apply to this case.
