Inflammatory myofibroblastic tumor of the stomach: an unusual complication after gastrectomy

Abstract

Inflammatory myofibroblastic tumor (IMT) is a benign lesion that was first described in the liver by Pack and Baker in 1953.1 It is a rare lesion that has been described in many organs and tissues of children and young adults: brain, eye, lung, heart, liver, gallbladder, extrahepatic bile ducts, GI tract, spleen, mesentery, breast, bladder, bone, and so on.2-7 IMT is also called inflammatory pseudotumor, plasmacell granuloma, inflammatory myofibroblastoma, and inflammatory myofibrohistiocytic proliferation. It causes constitutional symptoms, depending upon its location.8 It is an inflammatory solid tumor that microscopically contains spindle cells, myofibroblasts, plasma cells, lymphocytes, and histiocytes.9,10 This report describes an IMT of the gastric remnant in a patient with a prior gastrectomy.
