胰腺炎性肌纤维母细胞瘤（炎性纤维肉瘤）是非常罕见的。我们报告一位29岁的女性，因胰头长6公分的肿瘤造成阻塞性黄疸而接受胰管切除术。肿瘤累及局部，无明显转移。肿瘤由增殖的成纤维细胞/或成肌纤维细胞样梭形细胞和纤维粘液样基质中的慢性炎性细胞聚集体组成。免疫组化检查显示仅对波形蛋白有反应。这种肿瘤常发生在腹膜腔、腹膜后腔或盆腔，但发生在胰腺的情况非常罕见。
Inflammatory myofibroblastic tumors (inflammatory fibrosarcomas) of the pancreas are extremely rare. We report a 29-year-old woman who underwent pancreatoduodenectomy for a 6-cm tumor of the pancreas head causing obstructive jaundice. Tumor involvement was local, without apparent metastasis. The tumor was composed of proliferating fibroblastic/or myofibroblast-like spindle cells and aggregates of chronic inflammatory cells in a fibromyxoid matrix. Immunohistochemical examination demonstrated reactivity only to vimentin. This tumor has often been found in the peritoneal cavity, the retroperitoneum, or the pelvic cavity, but only very rarely in the pancreas.
