Herpes Zoster
Symptoms and Signs of Herpes Zoster
Lancinating, dysesthetic, or other pain develops in the involved site, typically followed within 2 to 3 days by a rash, usually crops of vesicles on an erythematous base. The site is usually one or more adjacent dermatomes in the thoracic or lumbar region, although a few satellite lesions may also appear. Lesions are typically unilateral and do not cross the midline of the body. The site is usually hyperesthetic, and pain may be severe. Lesions usually continue to form for about 3 to 5 days. Herpes zoster may disseminate to other regions of the skin and to visceral organs, especially in patients who are immunocompromised. (Ramsay Hunt syndrome, Herpes Zoster Oticus ) results from involvement of the geniculate ganglion. Ear pain, facial paralysis, and sometimes vertigo occur. Vesicles erupt in the external auditory canal, and taste may be lost in the anterior two thirds of the tongue. Herpes Zoster Ophthalmicus None Intraoral zosteris uncommon but may produce a sharp unilateral distribution of lesions. No intraoral prodromal symptoms occur. 1.Yawn BP, Wollan PC, Kurland MJ, St Sauver JL, Saddier P.
