A 60-year-old male with increasing abdominal distension was admitted to The Fifth Affiliated Hospital of Guangzhou Medical University (Guangzhou, China). The abdominal sonogram exhibited a huge abdominal cystic-based mass with solid components in the left upper quadrant. A contrast-enhanced computed tomography scan of the abdomen revealed a large heterogeneous cystic solid tumor, but the source of the tumor could not be determined. The laparotomy demonstrated a huge cystic-based tumor with an integrated cystic wall, arising from the posterior wall of the gastric body. Multiple septa and ~3,500 ml of yellowish fluid were found in the cystic cavity. Pathological analysis showed that the tumor contained a mixture of polygonal and spindle cells. Immunohistochemical study indicated that the tumor cells were positive for CD117 and CD34. The final diagnosis was gastric gastrointestinal stromal tumor. The patient recovered well and no recurrence or metastasis was identified following a 12-month follow-up.
一名腹胀进行性加重的60岁男性入住广州医科大学第五附属医院（中国广州）。腹部超声显示左上腹有一个巨大的以囊肿为基础的肿块，伴有实性成分。腹部增强计算机断层扫描显示一个大的异质性囊实性肿瘤，但肿瘤来源无法确定。剖腹手术显示一个巨大的以囊肿为基础的肿瘤，囊壁完整，起源于胃体后壁。囊腔内发现多个分隔及约3500毫升淡黄色液体。病理分析显示肿瘤含有多边形和梭形细胞的混合物。免疫组织化学研究表明肿瘤细胞CD117和CD34呈阳性。最终诊断为胃胃肠道间质瘤。患者恢复良好，随访12个月未发现复发或转移。
