Typical zoster in the vicinity of right popliteal fossa in a vertebral nerve L4 distribution.
Human herpesvirus (HHV) type 3. Intraoral herpes zoster closely resembles recurrent HHV-1 infection, but the lesions generally follow a dermatome and stop sharply at the midline, as shown here. However, the rules for common sites of occurrence of HHV-1 and HHV-3 often do not apply to patients who are immunocompromised. Courtesy of Sheldon Mintz, DDS.
