title: Inflammatory myofibroblastic tumor of the orbit.
abstract: The authors describe an unusual case of orbital inflammatory myofibroblastic tumor (IMT) in a 17-year-old patient who presented with a painful exophthalmos of the left eye. After complete surgical excision, the mass was diagnosed as an IMT based on morphological and immunohistochemical features. No tumor recurrence was evident during 28-month follow-up. The authors discuss histopathological and immunohistochemical characteristics and review the literature of orbital IMT.
