Bile duct schwannomas are rare benign tumors that frequently mimic more life-threatening tumors. Till date, only a few of these tumors have been diagnosed preoperatively. Herein, we report the case of a 68-year-old man who presented with a 1-day history of epigastralgia. The patient was preoperatively diagnosed with bile duct schwannoma using transpapillary biliary forceps biopsy and underwent local resection without major complications. The findings of our study indicate that endoscopic tumor biopsy may be helpful in diagnosing bile duct schwannoma before surgery; thus, enabling surgeons to plan an appropriate surgery while avoiding overtreatment.
胆管施万细胞瘤是一种罕见的良性肿瘤，常被误诊为更具威胁生命的肿瘤。迄今为止，这些肿瘤中只有少数在术前被诊断出来。在此，我们报告了一例 68 岁男性，因上腹痛 1 天就诊。术前通过经内镜胰胆管造影活检诊断为胆管施万细胞瘤，行局部切除术，无重大并发症。本研究结果表明，内镜下肿瘤活检有助于术前诊断胆管施万细胞瘤，从而使外科医生能够在避免过度治疗的情况下计划进行适当的手术。
