title: [The relationship between pleomorphic adenocarcinoma and dermatomyositis (with a case report and review of the literatures)].
abstract: OBJECTIVE
  The purpose of this article is to improve the understanding of complications of pleomorphic adenocarcinoma, and the possibility of complicated with dermatomyositis. In order to explore whether there is a certain relationship between the two diseases.
  
  
  METHODS

Reviewed the latest clinical literature relevant to pleomorphic adenocarcinoma and dermatomyositis.
  
  
  RESULTS
  The patients underwent superficial parotidectomy treatment. The postoperation pathologic and immunohistochemical examination confirmed the diagnosis of pleomorphic adenocarcinoma. Dermatomyositis improved better after the operation.
  
  
  CONCLUSIONS
  Pleomorphic adenocarcinoma has the possibility of complicated with dermatomyositis which may misdiagnosis in clinical practice. Summarize the latest diagnosis progress of pleomorphic adenocarcinoma and the surgical treatment of the tumor. Also discuss the standards of clinical diagnosis and treatment of dermatomyositis.
