Solitary fibrous tumor (SFT) is a mesenchymal tumor that rarely occurs in the abdomen. We report a very rare case of an abdominal SFT in the lesser omentum. A 39-year-old Korean man was referred to our center for management of a 9 cm incidental mass in the abdominal space found on a chest computed tomography (CT) during a routine medical examination. He had no symptoms, and there were no specific findings on physical examination. A contrast enhancement CT was performed, and an extraluminal gastrointestinal stromal tumor in the stomach or a pancreatic origin mass was suspected. Surgery was performed and an enclosed mass in the lesser omentum was observed, which was resected completely. The postoperative course was uneventful. Based on microscopy, the omental tumor was diagnosed as SFT.
孤立性纤维瘤（SFT）是一种间叶组织肿瘤，很少发生于腹部。我们报告了一例非常罕见的发生于小网膜的腹部SFT病例。一名39岁的韩国男性因在常规体检的胸部计算机断层扫描（CT）中发现腹部有一个9厘米的偶然肿块而被转诊至我们中心。他没有症状，体格检查也没有特殊发现。进行了增强CT检查，怀疑是胃外生性胃肠道间质瘤或胰腺来源的肿块。进行了手术，观察到小网膜内有一个包膜完整的肿块，并将其完全切除。术后过程顺利。根据显微镜检查，网膜肿瘤被诊断为SFT。
