Multiple esophageal rings: an association with eosinophilic esophagitis: case report and review of the literature.

Esophagitis may present endoscopically with erythema, edema, loss of vascular pattern, friability, and ulceration of the esophageal mucosa. Left untreated, chronic esophagitis may result in stricture formation. The presence of multiple concentric rings involving the entire esophagus has been cited as a chronic form of esophagitis. We present a case of an 8-yr-old boy with multiple concentric esophageal rings and histological evidence of eosinophilic esophagitis, who failed medical antireflux treatment and responded to an elimination diet.
