Inflammatory myofibroblastic tumor in the retromolar region of an 8-year-old child: A rare finding

摘要

© 2022 Journal of Oral and Maxillofacial Pathology.Inflammatory myofibroblastic tumor (IMT) of the oral cavity is an extremely rare finding. The etiology and pathogenesis of IMT is controversial and unclear. The tumor requires complete surgical excision and continuous monitoring of clinical consequences. The present article describes the clinical, histological, operative and immunohistochemical features of a case of IMT in the mandibular retromolar region of an 8-year-old male. Histologically, the lesion shows myofibroblastic spindle cell proliferations with infiltrative margins in an inflammatory background. Immunohistochemically, the myofibroblastic spindle cells in the present case were positive for α-smooth muscle actin and CD68 due to which the diagnosis of IMT was confirmed.
