AB Blistering  distal  dactylitis  is  a  cellulitis  of  the  fingertip  caused  by  group  A  β-hemolytic  Streptococcus  or,  less  often,  S  aureus  infection  in  children  from  infancy  to  teenage  years.  The  typical  lesion  is  a  seropurulent,  fluid-filled,  painful,  tense  blister  with  surrounding  erythema  located  over  the  palmar  fat  pad  on  the  distal  portion  of  a  finger  or  toe.  Polymorphonuclear  leukocytes  and  gram-positive  cocci  can  be  found  in  the  Gram  stain  of  the  purulent  exudate  from  the  lesion.  The  differential  diagnosis  includes  bullous  impetigo,  burns,  friction  blisters,  paronychia,  felon,  and  herpetic  whitlow.
