Idiopathic eosinophilic oesophagitis: atypical presentation of a rare disease.

A 72 year-old man presented severe dysphagia and weight loss of recent onset. Repeated oesophageal endoscopy and biopsies with macroforceps were normal. Oesophageal manometry disclosed features compatible with achalasia. Oesophageal EUS endoscopy localized an infiltrating process between muscular layers of the oesophageal wall and CT scan delimited a circular thickening in the inferior part of the oesophagus. Because of severe clinical presentation mimicking a possible oesophageal neoplasm like a lymphoma, partial oesophagectomy was performed and revealed eosinophilic oesophagitis. This unusual presentation emphasizes that idiopathic eosinophilic oesophagitis must be proposed in the differential diagnosis of dysphagia, even in old patient without apparent oesophageal lesion at endoscopy.
