We report an uncommon clinical case of anterior mediastinal localization of ectopic pancreatic tissue. A 39-year-old male was referred to our institution for investigation of an abnormal mediastinal shadow on a chest X-ray, and a large cystic lesion measuring 10 x 8 cm located in the anterior mediastinum was observed on a computed tomographic scan. He underwent complete surgical resection of the lesion. The postoperative pathological examination confirmed the diagnosis of ectopic mediastinal pancreas. No recurrence or metastasis was detected during a follow-up period of 8 years. We speculate that this lesion represents abnormal differentiation of the pluripotent epithelial cells of the ventral primary foregut. Details of the clinical and histopathological features are presented.
我们报告了一例异位胰腺组织位于前纵隔的罕见临床病例。一名39岁男性因胸部X线检查发现纵隔阴影异常而转诊至我院，计算机断层扫描显示前纵隔有一个大小为10×8 cm的巨大囊性病变。他接受了病变的完整手术切除。术后病理检查确诊为纵隔异位胰腺。在8年的随访期内未发现复发或转移。我们推测该病变代表腹侧原始前肠多能上皮细胞的异常分化。本文介绍了临床和组织病理学特征的详细情况。
