Ringed oesophagus and idiopathic eosinophilic oesophagitis in adults:: an association in two cases

Ringed oesophagus is an increasingly recognised finding in young people presenting with dysphagia and may be related to eosinophilic oesophagitis. Recently, hypotheses regarding potential aetiologies have been proposed but these have not been systemically tested in the majority of reported cases. We report two cases very similar in clinical history and endoscopic findings. An association with gastro-oesophageal reflux disease or motility abnormalities of the oesophagus were ruled out in both. Histological analysis revealed high-density infiltration of the oesophageal mucosa by eosinophils and excluded gastro-duodenal involvement. Examinations of the oesophagus at the time of low frequency dysphagia, some years before presentation to our centre, did not show rings, suggesting that multiple rings are a possible late complication of eosinophilic oesophagitis. Oesophageal dilatation effectively relieved dysphagia in our two patients. (C) 2004 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.
