title: [Image date and clinicopathologic features of myoepithelial carcinoma in parapharyngeal space].
abstract: OBJECTIVE
  To study the image data and clinicopathologic features of myoepithelial carcinoma in parapharyngeal space.
  
  
  METHODS
  Based on one patient with myoepithelial carcinoma of parapharyngeal space treated in our hospital, image data and clinicopathologic findings were analyzed. The clinical characteristics of myoepithelial carcinoma in head and neck region were discussed.
  
  
  RESULTS
  CT obviously showed the mass in parapharyngeal space with destruction of temporal bone. Immunohistochemical stain showed positive staining for S-100 protein, Smooth muscle actin, Cytokeratin and Vimentin. There were otalgia, bloody pus, headache and signs of cranial nerve lesion.
  
  
  CONCLUSIONS
  Myoepithelial carcinoma was a rare malignant epithelial neoplasm and had a poor prognosis. Myoepithelial carcinoma often occurrence in salivary gland of maxillofacial region. The clinical signs were otalgia and headache in patient with myoepithelial carcinoma in parapharyngeal space. CT image showed malignant neoplasm and surrounding tissues were destroyed. Diagnosis depends on pathology and immunohistochemistry.
