Follicular dendritic cell sarcoma (FDCS) is a rare mesenchymal tumor that typically develops in lymph nodes; it is clinically uncommon and has only occasionally been documented in cases of soft tissue, liver and spleen, and retroperitoneum; it is also extremely uncommon to develop in the stomach.
A 64-year-old woman who discovered a lump in her left upper abdomen 6 months prior and was taken to the hospital due to excruciating abdominal pain.
An abdominal computed tomography scan showed a soft tissue mass around the cardia. The immunohistochemical and postoperative histopathology results were compatible with FDCS.
The patient underwent "radical total gastrectomy and esophagojejunostomy" (Roux-Y anastomosis).
The patient recovered well 2 months after surgery.
We report a case of FDCS occurring in the stomach and abdominal cavity, which was unique in terms of clinical location, clinical presentation, and imaging signs. This case report aims to enhance clinicians' understanding and diagnosis of FDCS in the stomach and abdominal cavity and reduce the rate of clinical misdiagnosis.
滤泡树突细胞肉瘤（FDCS）是一种罕见的间叶组织肿瘤，通常发生在淋巴结中；临床上少见，仅偶尔在软组织、肝脏和脾脏以及腹膜后腔的病例中记录到；在胃中也极少见。
一名 64 岁女性，6 个月前发现左上腹部有肿块，因腹痛难忍被送往医院。
腹部计算机断层扫描显示贲门周围有软组织肿块。免疫组化和术后组织病理学结果符合 FDCS。
患者接受了“根治性全胃切除术和空肠食管吻合术”（Roux-Y 吻合术）。
术后 2 个月患者恢复良好。
我们报告了一例发生在胃和腹腔的 FDCS 病例，其在临床部位、临床表现和影像学特征方面均具有独特性。本病例报告旨在提高临床医生对胃和腹腔 FDCS 的认识和诊断，降低临床误诊率。
