RESUMO
BACKGROUND: Herpetic esophagitis (EH) usually affects those who are immunocompromised and is uncommon in immunocompetent patients. In these cases, EH may occasionally present as an acute and self-limited illness. Such cases are rare and only a few have beenreported and limited published reviews exist making the benefits of antiviral therapy in immunocompetent patients unknown. CASE PRESENTATION: We report four cases of young patients who presented dysphagia, odynophagia and epigastric pain. Endoscopic findings revealed lesions in the distal esophagus and histopathological changes compatible with herpes virus infection confirmed by viral DNA in every case. After treatment, every patient showed significant improvement and tolerated oral intake after discharge. CONCLUSIONS: In this publication, we present four immunocompetent patients with EH, without relevant alterations in laboratory workup and with negative HIV status. This disease is infrequent in patients with such characteristics and there are few cases published. In order to better understand this pathology, we present the symptoms, the endoscopic alterations and the clinical evolution with treatment. In our series, 50% of patients had serology compatible with acute HVS type 1 infection, 25% had a subacute infection pattern (IgM and IgG positive antibodies) and in another 25% of patients, serology was not done. No patient presented leukocyte alterations, while all patients presented with anatomopathological findings compatible with acute herpetic esophagitis and responded to acyclovir therapy.
