Summary A case of multicentric neoplasia of the colon is described. At least two of the lesions fit all the criteria for nonpolypoid carcinoma in situ, a lesion previously not described in that location. The lesions are believed to have been potentially malignant, but at the time of excision probably were benign. The incidental discovery of nonpolypoid carcinoma in situ of the colon should be an indication for local resection and careful search for additional bowel tumors.
