title: Gastrointestinal stromal tumor of the stomach and hepatocellular carcinoma: An unusual association.
abstract: BACKGROUND
  Gastrointestinal stromal tumors (GIST) are uncommon, potentially malignant tumors, that arise in the wall of the gastrointestinal tract. Up to 50% can develop metastasis, mainly in the liver, but the occurrence of synchronous primary liver tumors is a rare event in these patients.
  
  
  METHODS
  The authors report a case of the association of gastric GIST and hepatocellular carcinoma (HCC) in a non-cirrhotic liver in a 76 year-old patient.
  
  
  CONCLUSIONS
  The appearance of an hepatic lesion in a GIST patient does not necessarily imply its secondary nature.
  
  
  CONCLUSIONS
  In diagnosed GIST patients, all efforts should be pursued to characterize synchronous hepatic lesions, in order to plan a correct and tailored treatment of the patients.
