Inflammatory myofibroblastic tumor of the peripheral soft tissue: A case report

A 52-year-old woman presented with a painless lump at right buttock of 14 years duration with history of sudden increase in size for the last 2 months. Fine needle aspiration cytology (FNAC) examination suggested a fibrohistiocytic lesion. Histopathological examination with subsequent immunohistochemistry diagnosed the case as inflammatory myofibroblastic tumor (IMT) of the peripheral soft tissue. IMT of the peripheral soft tissue especially in older patients are comparatively rare and the case is reported for its rarity.
