Inflammatory Myofibroblastic Tumor of the Parotid Gland

Abstract

An inflammatory myofibroblastic tumor, previously known as an inflammatory pseudotumor, is an uncommon neoplasm. This tumor, which has characteristic morphologic and immunohistochemical features, is mostly seen in the lung. We present a rare case of an inflammatory myofibroblastic pseudotumor of the parotid gland. A 45-year-old woman presented with a 4-month history of a swelling in her right parotid region. A partial parotidectomy with preservation of the facial nerve branches was performed. The incidence of inflammatory myofibroblastic tumor in the parotid gland is low, and local resection is currently the best treatment. A prolonged postoperative follow-up period is necessary for patients with inflammatory myofibroblastic tumor. Inflammatory myofibroblastic tumor of the parotid gland is discussed with a brief literature review.
