title: [Epidermoid carcinoma of gallbladder: analysis of our casuistic].
abstract: BACKGROUND
  The most common type of gallbladder cancer is the adenocarcinoma. The squamous cell carcinoma represents only a 0-12% of all gallbladder tumors.
  
  
  METHODS
  124 cases of malignant neoplasias of the gallbladder were diagnosed during the last 33 years in the Department of Surgery of our hospital. From these cases, 5 were squamous cell carcinomas, representing 2.41% of our series.
  
  
  METHODS
  The ratio female: male was 1.5:1, and the mean age was 50.2 years. Liver involvement was observed in 4 of 5 patients at the moment of diagnosis. Four patients underwent surgery and one received palliative treatment with percutaneous bile dreinage. The mean survival was 14.5 months.
  
  
  CONCLUSIONS
  The tumor extention at the time of diagnosis is generally advanced and the outcome is not promising in this kind of gallbladder cancer.
