RESUMO
OBJECTIVE: Our objective was to present a case of inflammatory myofibroblastic tumor of the colon. BACKGROUND: Inflammatory myofibroblastic tumors are uncommon. They originate from soft tissues, their appearance is more frequent in childhood and your adulthood and these tumors are composed of myofibroblastic cells, leukocytes, and plasmatic cells. More frequently, these tumors originate in lungs, mesentery, liver and spleen; intestinal appearance is uncommon. METHOD: In a 42 year-old male with a lump in right iliac fossa, a colonic inflammatory myofibroblastic tumor infiltrating ileocecal valve was found. Right hemicolectomy was performed. After a 10-month follow-up, no complications were found and no adjuvant therapy was needed. CONCLUSIONS: Inflammatory myofibroblastic tumors have been well described, but, experience is quite limited; Symptoms are consequences of compressed organs in the vicinity. At present, no early detection devices are available, but genetical evaluations for the patient's family members may contribute to unravel a pattern of transmission of the disease.
