Herpes simplex (HS) is an opportunistic infection, primarily in immunocompromised patients, caused by herpes simplex virus. Oral and genital mucosa are the most commonly involved sites; it is rare for HSV to invade the esophagus and cause esophagitis, especially in immunocompetent patients. Here, we present a case where an immunocompetent patient presented with HS esophagitis, which had evolved into esophageal ulcers. He was successfully treated with acyclovir. Subsequently, we did a comprehensive literature search and tabulated all the possible complications and management plans of previously reported cases of HS in immunocompetent patients.
