title: [Anatomopathological study of 86 gastric adenomas. Experience in 14 years].
abstract: OBJECTIVE
  To analyze the clinical presentation, pathological aspect and treatment of gastric adenomas.
  
  
  METHODS
  Retrospective analysis of 75 patients aged 26 to 88 years in whom a gastric adenoma was diagnosed.
  
  
  RESULTS
  Seventy one patients had elevated endoscopical lesions and two had depressed or flat lesions. Ninety percent of lesions were located in the gastric antrum. Pathological study detected 6 focal carcinomas within the adenomas and 5 concomitant carcinomas located elsewhere in the stomach. Fifty four patients were subjected to endoscopical resection. Among patients with focal carcinomas, a gastrectomy was performed in four and endoscopical resection in two.
  
  
  CONCLUSIONS
  Gastric adenomas must be considered in the differential diagnosis of gastric elevated lesions and may be confused in early gastric cancer. There is a histological resemblance between adenomas and gastric dysplasia described by several authors though only in our cases and in the Japanese literature the adenoma is referred to as mostly a polypoid sessile lesion.
