阑尾肿瘤少见,症状酷似阑尾炎,常被忽视以致误诊.自1982年10月～1994年12月我们共搜集7例术前误诊的各种类型阑尾肿瘤,均经病理证实. The appendix tumors are rare, and the symptoms resemble appendicitis. They are often overlooked and misdiagnosed. From October 1982 to December 1994, we collected a total of 7 types of appendiceal tumors that were misdiagnosed before surgery and were confirmed by pathology.
