title: [Clinical pathological analysis of clear cell odontogenic carcinoma].
abstract: OBJECTIVE
  To investigate clinical pathological characteristics and biologic behavior of clear cell odontogenic carcinoma.
  
  
  METHODS
  Analysis of clinical data, microscopic and electromicroscopic observation of 8 cases of clear cell odontogenic carcinoma.
  
  
  RESULTS
  The tumor occurred mainly in female and involved right mandible. 37.5% had regional lymph node metastases at the time of operation. Recurrence rate was 33.3%. The tumor had no capsule and consisted of clear cell and basaloid cells which arranged in nests and strands. Tumor cells often grew close to the blood vessels and caused bone resorption. There were less cell organelle and swelling of mitochondria.
  
  
  CONCLUSIONS
  This tumor belongs to middle grade malignant tumor and should be called clear cell odontogenic carcinoma.
