title: Observations on the vascular structure of malignant tumours of the mandible using specimen arteriography.
abstract: OBJECTIVE
  To investigate the vascular structure of different malignant tumours of the mandible.
  
  
  METHODS
  Specimen arteriography was performed on seven cases of squamous cell carcinoma of gingiva and four sarcomas.
  
  
  RESULTS
  Malignant tumours could be divided into two groups: (1) the hypervascular sarcomas in in which the arteries were dilated, distributed evenly and arranged in a bush-like pattern; and (2) hypovascular squamous cell carcinoma with scanty arteries distributed unevenly without dilatation; in some areas, the shape of arteries was irregular and arranged in a network pattern.
  
  
  CONCLUSIONS
  The variation in vascular structure of malignant tumours of the mandible may be related to the outcome of regional chemotherapy.
