Glossopharyngeal zoster (herpes pharyngis) and vagal zoster (herpes laryngis) involve the jugular and petrosal ganglia, which are adjacent and often involved in some combination; however, individual involvement of both ganglia has been observed. Painful vesicular rash typically involves the palate, posterior tongue, epiglottis, tonsillar pillars, and, occasionally, the external ear. A unilateral distribution can distinguish this variation of zoster from herpes simplex and herpangina.
