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 1 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.
