Herpes simplex virus and the alimentary tract.

Herpes simplex virus (HSV) infection is well known as a sexually transmitted disease. However, relatively little has been published concerning the presentations and treatment of HSV infection within the gastrointestinal tract, where HSV most commonly affects the esophagus in both immunocompromised and immunocompetent patients. HSV proctitis is not uncommon and occurs primarily in males having sex with males.
