| Summary: | Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumors of unknown etiology composed of myofibroblastic cells admixed with inflammatory cells. Presented is a 72-year-old male hospitalized for severe abdominal pain and hematochezia with onset of associated symptoms of fever and sweats a few hours prior to abdominal pain. A computed tomography (CT) demonstrated left colonic thickening interpreted as partial obstruction, gross adhesions, and ischemia. At surgery, marked bowel ischemia from the distal transverse to proximal sigmoid colon was seen with extensive gross adhesions. Histopathology revealed a mesenteric mass chiefly composed of stellate-to-spindled myofibroblastic cells and fibrous adhesions, intermixed with lymphocytes, histiocytes, and plasma cells. The tumor was positive for desmin, smooth muscle actin, and keratin; tumor staging, grade, and postsurgical follow-up were not completed as the patient expired postoperatively. Illustrated is a rare pathologic mimic of ischemic colitis with fibrous adhesions, IMT. Thus, it should not be assumed that fibrous adhesions are always the etiology of obstruction when “adhesions” between sections of bowel are noted radiologically or surgically. |
