AB  - Herpes  zoster  is  a  dermatomal,  unilateral  reactivation  of  the  varicella  zoster  virus.  All  ages,  including  infants,  can  be  affected.  The  eruption  may  occur  anywhere  but  most  commonly  occurs  on  the  face  and  trunk.  Pruritus,  pain,  tenderness,  and  dysesthesias  may  present  4  to  5  days  prior  to  an  eruption  composed  of  umbilicated,  grouped  vesicles  on  an  erythematous,  edematous  base.  The  vesicles  may  become  purulent  or  hemorrhagic.  Occasionally,  nerve  involvement  may  occur  without  cutaneous  involvement.  Rare  presentations  involve  multiple  dermatomes  or  cross  midline.  Ophthalmic  zoster  (see  related  item)  involves  the  nasociliary  branch  of  the  5th  cranial  nerve  and  presents  with  vesicles  on  the  nose  and  cornea  (Hutchinson  sign).  Ramsay  Hunt  syndrome  (see  related  item)  is  a  herpes  zoster  infection  of  the  geniculate  ganglion  with  tinnitus,  decreased  hearing,  facial  palsy,  and  vesicles  on  the  tympanic  membrane,  pinna,  and  ear  canal.
