title: [Dermatomyositis and nasopharyngeal carcinoma: 3 cases].
abstract: BACKGROUND
  Nasopharyngeal carcinoma is a common cancer in Tunisia with an estimated incidence of 1.8/100,000. The tumor shows a characteristic association with paraneoplastic syndromes.
  
  
  METHODS
  We report three cases of histologically proven dermatomyositis associated with nasopharyngeal carcinoma in patients aged 40, 24 and 65 years. In all cases, the course of the paraneoplastic syndrome ran parallel to the nasopharyngeal carcinoma.
  
  
  CONCLUSIONS
  Dermatomyositis is one of the numerous paraneoplastic syndromes associated with nasopharyngeal carcinoma. Systematic examination of the nasopharynx is required in case of dermatomyositis.
