title: Simultaneous palatal pleomorphic adenoma and mandibular keratocystic odontogenic tumor in a pediatric patient.
abstract: BACKGROUND
  Neoplasms of the salivary gland account for 3% of all head and neck tumors; most of these occur in the parotid gland and are benign; 80% of them are pleomorphic adenomas. Benign neoplasms of the salivary gland are rare in children compared with adults. Keratocystic odontogenic tumor (KCOT) is considered the second most frequent neoplasm of all odontogenic tumors after the ameloblastoma. In the present report, we introduce the unusual presentation of a child with a simultaneous pleomorphic adenoma of the right hard palate and a KCOT of the left mandibular angle.
  
  
  CONCLUSIONS
  The case is significant for 2 reasons; according to the literature, there are few reports of pleomorphic adenoma arising from a minor salivary gland of the palate in a patient younger than 18 years. This is to our knowledge the first recorded instance of simultaneous palatal pleomorphic adenoma and mandibular KCOT occurring in a child.
