Rare Etiology of Odynophagia in a Female Adolescent.

Herpes esophagitis (HE) is a rare condition in immunocompetent adolescents. However, it commonly occurs as a primary infection in younger individuals. Herein, we report a 16-year-old female patient who had a history of fever for 5 days, odynophagia, and orolabial herpes infection for 7 days. Clusters of painful vesicles on an erythematous base on the lips, gingiva, and palate were observed on physical examination. Further, esophagogastroduodenoscopy revealed diffuse linear ulcerations in the distal esophagus. The patient then received the following treatment: intravenous (I.V.) acyclovir 5 mg/kg three times a day, I.V. omeprazole 40 mg two times a day, and acyclovir 5% cream four times a day. After 8 days of admission, the patient was discharged. A follow-up esophagogastroduodenoscopy was performed 7 weeks after discharge, and the results revealed that the esophageal mucosa had a normal appearance. The effect of antiviral treatment against HE remains unknown in these patients. Nevertheless, it is believed to accelerate the healing process in individuals with esophageal mucosal barrier damage. To the best of our knowledge, this case of a female adolescent with an intact immune system is the sixth case of herpes simplex esophagitis to be reported in the literature.
