The most common organ where follicular dendritic cell sarcoma (FDCS) occurs is in cervical lymph nodes, while few cases are found in extranodal organs such as liver, spleen, and soft tissue. This is a case report that FDCS occurs in the hepatogastric ligament. To our knowledge, there is no such case that has been reported previously. A 47-year-old male patient was found to have an intraabdominal mass during an annual physical examination. Computed tomography showed a 4.2 cm × 4.1 cm mass located at the lesser curvature of the stomach, above the pancreas. During operation, a tumor mass was found in the hepatogastric ligament and a radical resection was performed. The tumor was diagnosed as FDCS by pathology and immunohistochemical testing. The patient had a favorable recovery, and no obvious abnormality was found 3 months post-operation.
滤泡性树突状细胞肉瘤（FDCS）最常见的发生部位是颈部淋巴结，而在肝、脾和软组织等结外器官中发现的病例较少。本文报告1例发生于肝胃韧带的FDCS。据我们所知，此前尚无此类病例的报道。一名47岁男性患者在年度体检中发现腹内有肿物。计算机断层扫描显示一个4.2 cm×4.1 cm的肿物位于胃小弯处、胰腺上方。手术中，在肝胃韧带发现一个肿瘤肿物，并进行了根治性切除。通过病理及免疫组化检测，该肿瘤被诊断为FDCS。患者恢复良好，术后3个月未发现明显异常。
