The case of a 67-year-old woman with recurrent herpetic infection of the hard palate localized to the mucosa overlying a torus palatinus is presented. The rarity of reported cases of recurrent herpetic infections affecting the mucous membranes of the mouth exclusive of the lips cannot be adequately explained. Recurrent herpetic disease has been ascribed most commonly to the latency of the virus in epithelial and dermal tissues, but no proof of this has ever been found. However, exogenous reinfection or chronic multiplication of the virus in sites that have access to the eye and mouth probably is the more likely source for the recurrent disease.
