摘要
Inflammatory myofibroblastic tumors （IMTs） or inflammatory pseudotumors （IPs） have been extensively discussed in the literature. They are usually found in the lung and upper respiratory tract. However, reporting of cases involving the biliopancreatic region has increased over recent years. Immunohistochemical study of these lesions limited to the pancreatic head or distal bile duct seems to be compatible with those observed in a new entity called autoimmune pancreatitis, but usually intense fibrotic reaction （zonation） predominates producing a mass. When this condition is limited to the pancreatic head, the common bile duct might be involved by the inflammatory process and jaundice may occur often resembling adenocarcinoma of the pancreas. We have previously reported a case of IMT arising from the bile duct associated with autoimmune pancreatitis which is an extremely rare entity. Four years after Kaush-Whipple resection, radiological examination on routine follow-up revealed a tumor mass, suggesting local recurrence. Ultrasound-guided FNA confirmed our suspicious diagnosis. This present case, as others, suggests that persistent follow-up is necessary in order to prevent irreversible liver damage at this specific location.
煽动性的 myofibroblastic 肿瘤(IMT ) 或煽动性的假肿瘤(IP ) 广泛地在文学被讨论了。他们通常在肺和上面的呼吸道被发现。然而，包含 biliopancreatic 区域的案例报导在最近的年增加了。限制到胰腺的头或远侧的胆汁管的这些损害的 Immunohistochemical 学习似乎与那些在称为自体免疫的胰腺炎的一个新实体观察了兼容，但是通常强烈的纤维变性反应(带状配列) 支配生产一个团。当这个条件限于胰腺的头时，胆总管可能被煽动性的过程包含，黄疸可以经常发生类似于胰的腺癌。我们以前报导了从与是一个极其稀罕的实体的自体免疫的胰腺炎联系的胆汁管产生的 IMT 的一个案例。在 Kaush-Whipple 切除术以后的四年，平淡的后续上的放射学的检查揭示了一个肿瘤团，建议本地复发。指导超声的 FNA 证实了我们的可疑诊断。作为其它，这个现在的案例建议坚持的后续是必要的以便在这个特定的地点阻止不可逆的肝损坏。
