类癌又称嗜银细胞癌,可发生于胃肠道、气管、支气管、胰腺、胆管、卵巢等部位。但发生于胃肠道占90%以上,占消化道肿瘤的1～15%。因该病在临床上无特征性,常易误诊。现将我院经手术后病理证实的4例肠道类癌报告如下。例1:男性,27岁。因大便表面带鲜红色血8个月余,于1978年6月入院。查体无明显阳性体征。直肠镜检查距肛门7cm处有2个绿豆大、质稍硬、触时 Carcinoid tumors, also known as argyrophil cancer, can occur in the gastrointestinal tract, trachea, bronchi, pancreas, bile ducts, and ovaries. However, it occurs in more than 90% of the gastrointestinal tract and accounts for 1 to 15% of digestive tract tumors. Because the disease is clinically uncharacterized, it is often misdiagnosed. The 4 cases of intestinal carcinoid confirmed by pathology after surgery in our hospital are reported below. Example 1: Male, 27 years old. Due to the stool surface with bright red blood more than 8 months, admitted to hospital in June 1978. There were no obvious positive signs in the examination.
