Dysphagia in Children, Do Not Blame Eosinophils Too Quickly.

Dysphagia in children is a relatively frequent symptom in childhood, and the main causes are congenital and linked to ear-nose-throat etiologies. However, non-congenital esophageal dysphagia is less common, and the main cause in such cases is eosinophilic esophagitis (EoE). When there is no response to a well-conducted treatment, with normalization of histology, the diagnosis of EoE must then be reconsidered. Here, we present the case of a 10-year-old patient whose initial diagnosis of eosinophilic esophagitis delayed the diagnosis of type III achalasia.
