title: Vascular transformation of sinuses in bilateral cervical lymph nodes.
abstract: BACKGROUND
  Vascular transformation of sinuses (VTS) in lymph node has been infrequently reported. We present a case of incidental VTS in bilateral cervical nodes discovered at the time of operation for tongue cancer.
  
  
  METHODS
  Standard histopathologic review was undertaken.
  
  
  RESULTS
  In this case, a spectrum of varied vasoformative patterns involving lymph nodes in either a pan-nodal or localized fashion were identified. The hilum was occupied by smooth muscle proliferation and adipose tissue. Two nodes also displayed similar features of angiolipomatous hamartoma. No metastatic carcinoma was found in lymph nodes with VTS.
  
  
  CONCLUSIONS
  This case suggests that lymphovenous congestion and distention represented the major cause through which VTS developed.
