Inflammatory myofibroblastic pseudotumours are uncommon lesions of unknown etiology. Diverse nomenclature such as inflammatory pseudotumour, plasma cell granuloma, inflammatory myofibroblastoma and inflammatory myofibrohistioblastic proliferation have been used for this entity due to uncertainity regarding true biologic nature of these lesions. This tumour is composed of spindle cells with myofibroblastic proliferation accompanied by an inflammatory infiltrate of plasma cells. Since it was first described in 1937, the understanding of inflammatory myofibroblastic pseudotumour has evolved from a reactive inflammatory process to a neoplasm of intermediate biological potential. These are associated with nosologic, histogenetic and aetiopathogenetic controversy. They occur in all age groups and in diverse body sites, with equal propensity in males and females
