Inflammatory myofibroblastic tumour is a rare benign neoplasm that has clinical presentations which may mimic malignancy. Most occur in childhood or early adulthood involving the lungs or orbits, but may occur at any age and in any organ system. Preoperative recognition of this quasineoplastic lesion is important, so as to avoid unnecessary radical resection. We report on an infant with an inflammatory myofibroblastic tumour in the soft tissue of the posterior neck, which is a rare site of presentation.
