title: Venous lake of the lip treated with a sclerosing agent: report of two cases.
abstract: BACKGROUND
  A venous lake is a venous ectasia that appears mostly on the lower lip and other sun-exposed areas of an older person. Treatment of lip venous lake includes surgical excision, laser therapy, infrared coagulation, and cryotherapy. Although the use of sclerotherapy on varicose veins, leg telangiectasia, hemorrhoids, and hemangiomas is well established, the use of sclerotherapy for lip venous lake has not been reported.
  
  
  OBJECTIVE
  We present two cases of lip venous lake treated with intralesional injection of 1% polidocanol.
  
  
  METHODS
  Two cases are reported, and literature is reviewed.
  
  
  RESULTS
  The lesions virtually disappeared, leaving an inconspicuous scar, with two sessions of sclerotherapy. Side effects were not observed.
  
  
  CONCLUSIONS
  Sclerotherapy with polidocanol is effective in the treatment of lip venous lake and offers an alternative to conventional methods.
