Carcinoma in situ of the vermiform appendix associated with adenomatosis of the colon.
A case is reported of carcinoma in situ of the vermiform appendix associated with adenomatosis of the colon. Histologic examination revealed the presence of tubulovillous adenocarcinoma in an adenoma. Other lesions associated with this neoplasm were multiple adenomatous polyps in the colon and duodenum and two fibromas in the neck. Since the vermiform appendix is a part of the large intestine, it should be expected that careful examination may reveal the adenomatous involvement and may lead to the discovery of carcinoma in situ.
