Gastrointestinal stromal tumors (GISTs) are rare in young individuals and typically affect older adults. We present the case of a previously healthy male who presented with severe hematochezia, fatigue, and dizziness. Colonoscopy did not demonstrate any colonic mass. CT of the pelvis with contrast revealed a pelvic mass measuring 7.4 cm. Biopsy confirmed a low-grade mixed-type GIST of the terminal ileum. Surgical resection was successfully performed. Histopathological analysis further characterized the tumor, and the patient was discharged with consideration of adjuvant imatinib therapy. This case underscores the importance of thorough diagnostic evaluation and multidisciplinary management for atypical presentations of gastrointestinal bleeding in young patients.
胃肠道间质瘤（GISTs）在年轻人中较为罕见，通常影响老年人。我们报告一例既往健康的男性病例，该患者出现严重便血、疲劳和头晕。结肠镜检查未发现任何结肠肿物。盆腔增强CT显示一个7.4厘米的盆腔肿物。活检证实为回肠末端低级别混合型GIST。成功进行了手术切除。组织病理学分析进一步明确了肿瘤特征，患者出院时考虑接受辅助伊马替尼治疗。该病例强调了对年轻患者非典型胃肠道出血表现进行全面诊断评估和多学科管理的重要性。
