A case report: asymptomatic esophageal eosinophilia after herpes simplex esophagitis. Controversies in the therapeutic approach.

The coexistence of eosinophilic esophagitis and herpes simplex virus in patients has been published in numerous case reports in the last few years. Both entities can be diagnosed simultaneously or one prior to the other, raising a possible causal relationship. Esophageal eosinophilia is a histological finding, and its underlying cause should be investigated. Eosinophilic esophagitis is one of the most common causes of esophageal eosinophilia. Eosinophilic esophagitis is a clinicopathologic disease, which is characterized by dysphagia and food impaction. We present a case of a patient with asymtomatic esophageal eosinophilia diagnosed after herpetic esophagitis. Other causes of esophageal eosinophilia were ruled out. Given the recent association between eosinophilic esophagitis and esophagitis due to herpes simplex virus, we find ourselves facing a dilemma about assessing the need or not to initiate early treatment.
