Abstract A case of inflammatory myofibroblastic tumour (IMT) arising in the tongue of a 27-year-old man is described. The patient presented with a solitary, well-circumscribed submucosal mass of 4 months duration. The tumour showed in its largest part a paucicellular sclerosing lesion resembling a hyalinizing granuloma surrounded by a thin rim of an admixture of myofibroblasts, plasma cells and foamy histiocytes. Myofibroblasts expressed vimentin and alpha-smooth muscle actin positive immunophenotypes. Ultrastructurally the hyaline areas were composed of abundant collagen fibres with sparse myofibroblasts. Extensive scar-like change in this IMT may be related to a traumatic insult.
