A case of squamous cell carcinoma arising in a cystic duplication within the small bowel mesentery of a 65-yr-old man is described. The cyst wall had a double layered smooth muscle coat with intervening ganglionic plexus; part of the cyst was lined by ciliated columnar epithelium. Twelve previously reported cases of carcinoma arising in duplications are reviewed together with present case. In all but one case, the onset of symptoms was probably related to malignant change; the age at presentation ranged from 26 to 65 yrs. Pre-operative diagnosis proved difficult, and led to a delay in the appropriate treatment of some of the five cases involving duplications of the rectum. Duplications of the alimentary tract are encountered only occasionally in adults; malignant change, although rare, should be recognised as a possible complication.
本文描述了一例发生在一名65岁男性小肠系膜囊性重复畸形内的鳞状细胞癌。囊肿壁有双层平滑肌层，其间有神经节丛；囊肿部分内衬有纤毛柱状上皮。将12例先前报道的发生于重复畸形内的癌病例与本病例一起进行了回顾。除1例病例外，所有病例症状的出现可能与恶变有关；就诊时的年龄范围为26至65岁。术前诊断困难，导致涉及直肠重复畸形的5例病例中的一些病例未能得到及时恰当的治疗。消化道重复畸形在成人中仅偶尔遇到；恶变虽然罕见，但应被视为一种可能的并发症。
