AB A  9-year-old  boy  presented  to  the  office  with  a  2-day  history  of  fever  and  sore  throat.  At  the  time  of  presentation,  he  and  his  mother  noted  some  painful  bumps  on  his  lower  legs,  and  denied  trauma  (Figure  152-1).  No  history  of  recent  cough  or  change  in  bowel  habits  was  reported.  The  patient  had  no  chronic  medical  problems,  took  no  medications  and  had  no  known  drug  allergies.  On  examination,  his  oropharynx  revealed  tonsillar  erythema  and  exudates.  Bilateral  lower  extremities  were  spotted  with  multiple  slightly-raised,  tender,  erythematous  nodules  that  varied  in  size  from  2  to  6  cm.  Rapid  strep  test  was  positive  and  he  was  diagnosed  clinically  with  erythema  nodosum  (EN)  secondary  to  group  A  β-hemolytic  Streptococcus.  He  was  treated  with  penicillin  and  NSAIDs.  He  experienced  complete  resolution  of  the  EN  within  6  weeks.
