Recent reviews stressing the existence of synchronous and metachronous noncarcinoid neoplastic lesions in the same segment of an organ stimulated a review of experience with simultaneous small-bowel carcinoids and colonic carcinoma. Four cases of colonic malignancy associated with small-bowel carcinoid are presented. Included are cases with multiple carcinoids and concurrent multiple carcinomas; two metachronous carcinomas with subsequent ileal carcinoids, and three cases explored for colonic carcinoma with the discovery of incidental ileal carcinoids. There are few reports describing this variety of situations. The occurrence of concurrent malignant lesions, particularly more than one metachronous lesion in primary carcinoid cases, is uncommon.
近期的综述强调了在同一器官的同一节段中存在同步和异时性非类癌肿瘤性病变，这促使我们回顾同时存在小肠类癌和结肠癌的经验。本文报告了4例与小肠类癌相关的结肠恶性肿瘤病例。其中包括多例类癌和同时存在的多发癌；2例异时性癌伴随后发的回肠类癌，以及3例因结肠癌而进行探查时意外发现回肠类癌的病例。很少有报道描述这种情况。同时存在恶性病变，特别是在原发性类癌病例中出现一个以上的异时性病变，这种情况并不常见。
