title: [A clinical pathological study on cavernous venous malformation of the body surface].
abstract: OBJECTIVE
  To investigate the clinical pathology of cavernous venous malformations of the body surface.
  
  
  METHODS
  Tissue samples of cavernous venous malformations from 42 cases were stained with hematoxylin and eosin to observe the pathologic structure. The clinical manifestations and case history were summarized accordingly.
  
  
  RESULTS
  There was no distribution difference of the malformation in sex and body sides, but with obvious difference in anatomic sites. The malformation occurred most frequently at the head and neck, more frequently at extremities and least frequently at the trunk. According to pathologic structure, cavernous venous malformations of the body surface can be divided into three types: the cellular, the canaliform and the mixed.
  
  
  CONCLUSIONS
  The cause of distribution difference in anatomic sites remains unclear. Internal hemorrhage and infection may account for the increased growth and ache of the lesion. The different pathologic structure of the malformation may cause different clinical manifestations.
