Barrett's esophagus in anorexia nervosa: a case report.

Barrett's esophagus (BE) is a metaplastic lesion that may result from long-lasting gastroesophageal reflux and it is an established precursor of esophageal adenocarcinoma. There are reports of an increased prevalence of BE, and eventually esophageal adenocarcinoma, in patients with eating disorders characterized by purging behaviors like those with bulimia nervosa (BN). Among patients with eating disorders, those affected by anorexia nervosa binging purging subtype (ANBP), are behaviorally very similar to those with BN, but to our knowledge there are no data in literature about BE in patients with ANBP. We present the case of a 37-year-old female with a 20-year history of ANBP in comorbidity with bipolar disorder, who developed a BE requiring multi-specialistic intervention.
