The synchronous occurrence of tumors of different histological types in the stomach is uncommon. This rare association is usually detected incidentally at gastroscopy, surgery or histopathology. It is still not known whether such association represents an incidental coexistence or indicates a similar pathogenesis in the simultaneous development of tumors of different histological types in the same organ. A 73-year-old woman complained of discomfort after eating a Chinese dumpling, and had tarry stools three times. Gastroscopy showed a tumor at the juncture of the gastric fundus and corpus. The tumor was composed of gastric adenocarcinoma and gastrointestinal stromal tumor, in which the two components were intermixed with each other. To the authors' knowledge there are few reports of this extremely rare collision tumor association.
胃内不同组织学类型肿瘤同时发生的情况并不常见。这种罕见的关联通常是在胃镜检查、手术或组织病理学检查中偶然发现的。目前尚不清楚这种关联是代表偶然共存，还是表明同一器官内不同组织学类型肿瘤的同时发生具有相似的发病机制。一位 73 岁女性在吃了一个中国饺子后感到不适，并出现三次柏油样便。胃镜检查显示胃底部和体部交界处有一个肿瘤。该肿瘤由胃腺癌和胃肠道间质瘤组成，其中两种成分相互混合。据作者所知，这种极其罕见的碰撞瘤关联的报道很少。
