title: Pilomatrixoma in the differential diagnosis of pathologic calcification of the paraoral soft tissue.
abstract: As an incidental finding a firm nodule was palpated in the skin overlying the right angle of the mandible in a 78-year-old female. The radiograph showed a dense calcification. Histologically the lesion proved to be a pilomatrixoma. A brief review of the literature of the pilomatrixoma is presented. Finally, some comments are made about calcification in the paraoral region, especially in the lateral aspect of the neck.
