AB  - A  felon  is  a  subcutaneous  infection  or  abscess  in  the  pulp  space  on  the  palmar  aspect  of  the  fingertip  (Figure  133-1).  It  is  usually  caused  by  penetrating  trauma,  an  abrasion,  spread  from  adjacent  tissues  (e.g.,  eponychium,  osteomyelitis,  or  paronychia),  or  a  minor  cut  that  leads  to  the  invasion  of  bacteria.1  A  felon  can  develop  in  the  presence  of  a  foreign  body  (e.g.,  wood  splinter  or  thorn).2  It  can  be  iatrogenic  from  multiple  fingersticks  for  blood  glucose  measurement.3,4  The  offending  organism  is  usually  Staphylococcus  aureus.5  Mixed  infections  and  gram-negative  infections  may  occur  in  the  immunocompromised  patient.  A  felon  can  less  commonly  occur  on  the  toes.  The  information  in  this  chapter  can  be  applied  to  a  felon  of  the  finger  or  the  toe.
