Nodular fasciitis is a benign pseudosarcomatous proliferative lesion of the soft tissue, found in the subcutaneous fascia, usually of the upper extremity or trunk. It is frequently found to be a rapidly growing mass, and so it should be cautioned not to misdiagnose to be a malignant neoplasm.<BR>Accumlation of a large series of nodular fasciitis in the orofacial region indicates that this anatomic site is perphaps uncommonly but certainly not rarely affected. This report deals with the detailed description of a case of nodular fasciitis in the mandible and made a review of the literatures.<BR>The patient, a 3-year-old girl reffered to the clinic with the chief complaint of a tumor mass in the left inferior border of mandible.<BR>The rentgenologic examination revealed a periosteal reaction at the cortical bone adjacent to the tumorous lesion. A consequence of the histopathological study on the biopsy material showed nodular fasciitis.<BR>Follow-up information is favorable and proves the benign nature of the lesion. Differential diagnosis in relation to the other benign and malignant tumors in the region is also discussed.
