Inflammatory myofibroblastic tumor (IMT) is an uncommon mass lesion composed of a variety of inflammatory and other mesenchymal cells. Although IMT was originally reported in the lung, it is now recognized that IMT can occur in a variety of organs. The occurrence of IMT in the pancreas, however, is rare. Here, we report a case of IMT arising from the head of the pancreas in a 55-year-old man. He underwent pancreaticoduodenectomy, with the diagnosis of carcinoma of the pancreas; the pathological diagnosis of the tumor was IMT. By referring to previously reported cases, we conclude that, in the management of IMT in the pancreas, surgical excision is the primary choice, in order to obtain a definitive diagnosis as well as to relieve symptoms, and strict follow-up after surgery is required.
炎性肌纤维母细胞瘤（IMT）是一种由多种炎性细胞和其他间充质细胞组成的罕见肿块性病变。尽管IMT最初是在肺部被报道的，但现在人们认识到IMT可发生于多种器官。然而，IMT发生于胰腺的情况较为罕见。在此，我们报告一例55岁男性胰腺头部发生的IMT病例。他接受了胰十二指肠切除术，术前诊断为胰腺癌；肿瘤的病理诊断为IMT。通过参考既往报道的病例，我们得出结论，在胰腺IMT的治疗中，手术切除是首选，以便获得明确诊断并缓解症状，术后需要严格随访。
