Herpes simplex esophagitis in the immunocompetent patient: report of four cases and review.

Esophagitis due to herpes simplex virus is a well-recognized entity in immunocompromised patients but has only rarely been described in apparently immunocompetent hosts. We report four cases and review 27 additional cases identified in the English-language literature. Odynophagia, retrosternal chest pain, and fever are the most common symptoms. Single-contrast esophagography is insensitive and nonspecific, but double-contrast esophagography may be of more diagnostic value. Esophagoscopy with biopsy or collection of aspirate for cytologic examination and culture are required to make a definitive diagnosis. Patients are predominantly male, and most cases are associated with primary infection. Viral isolates were typed in 13 cases and were always type 1. Herpes simplex esophagitis in the immunocompetent patient is a self-limited infection; however, therapy with acyclovir may attenuate infection and hasten resolution of symptoms.
