title: Radiologic appearance of primary jaw lesions in children.
abstract: BACKGROUND
  The jaw (an unusual site of primary tumors in children and adolescents) has lesions often found incidentally by dentists on routine panoramic radiographs or during examination of a child who has swelling or tooth pain.
  
  
  OBJECTIVE
  This pictorial seeks to familiarize pediatric radiologists with the radiographic appearance of a variety of primary jaw lesions.
  
  
  METHODS
  We retrospectively searched institutional records for cases of primary jaw lesions in children and adolescents. Jaw lesions were characterized as: I, well-circumscribed radiolucent lesions; II, lesions with mixed or variable appearance; III, poorly circumscribed radiolucent lesions; and IV, radiopaque lesions.
  
  
  RESULTS
  Although most oral and maxillofacial lesions in children are benign, a broad spectrum of tumors was identified; lesions may occur in patients with unrelated prior malignancy.
  
  
  CONCLUSIONS
  Because radiologic studies may identify jaw lesions and direct further care, familiarity with the appearance of these entities is prudent.
