title: Esophageal remnant cancer 35 years after acidic caustic injury: A case report.
abstract: BACKGROUND
  Esophageal squamous cell carcinoma has been described as a long-term consequence following ingestion of corrosive substances.
  
  
  METHODS
  We report a rare case of a 62-year-old female patient with a history of acidic caustic injury 35 years ago, for which she had undergone near total esophagogastrectomy with right colon interposition. Recently, she presented with worsening dysphagia, weight loss, neck swelling and chest pain. After the diagnostic workup, an invasive squamous cell carcinoma of the esophagus was confirmed. To our knowledge, this is the first such report in the literature.
  
  
  CONCLUSIONS
  The risk for esophageal carcinoma increases substantially after ingestion of caustic substances. It is notable that distinct patterns of carcinogenesis between acids and alkalis may be postulated, since the corresponding pathophysiological impact of each one differ significantly. Although such esophageal cancers tend to have good prognosis due to early detection, both the diagnostic and therapeutic strategy may be challenging due to the limited available data in this field. Surgical treatment does not seem to eliminate the risk of cancer, as evident upon the present case report.
  
  
  CONCLUSIONS
  Optimal management of esophageal corrosive injuries remains a debatable issue in terms of choosing between conservative therapy and surgical intervention. For this reason, the need for long-term follow up regardless the ingested substance and the preferred therapeutic approach is highlighted.
