title: Gastric adenocarcinoma mimicking achalasia in a 15-year-old patient: a case report and review of the literature.
abstract: Although adenocarcinoma of the cardia is extremely rare in adolescent patients, the endoscopist should be alert to this disease in patients of any age with dysphagia, even if symptoms, and results of a barium study, upper endoscopy, and esophageal manometry are suggestive of primary achalasia, especially if family history is negative for achalasia. In addition, secondary achalasia should be suspected in patients who do not respond to therapy with botulinum toxin within 2 months. Because none of the mentioned tests can distinguish between primary achalasia and secondary forms due to carcinoma of the cardia, biopsy specimens should be obtained. It appears that, although there is a minimal risk for complications, a diagnostic procedure such as biopsy would be appropriate when the information obtained could be essential. In some cases EUS can be an additional diagnostic tool, because lesions of the submucosa and the surrounding area can be identified by EUS.
