AB A  young  woman  presented  to  the  office  with  several  days  of  overall  malaise,  fever,  and  sore  throat.  At  the  time  of  presentation  she  noted  some  painful  bumps  on  her  lower  legs,  and  denied  trauma  (Figure  186-1).  No  history  of  recent  cough  or  change  in  bowel  habits  has  been  reported.  The  patient  had  no  chronic  medical  problems,  took  no  medications,  and  had  no  known  drug  allergies.  Her  temperature  was  slightly  elevated,  but  other  vitals  were  normal.  On  examination,  her  oropharynx  revealed  tonsillar  erythema  and  exudates.  Bilateral  lower  extremities  were  spotted  with  slightly  raised,  tender,  erythematous  nodules  that  varied  in  size  from  2  to  6  cm.  Rapid  strep  test  was  positive,  and  she  was  diagnosed  clinically  with  erythema  nodosum  (EN)  secondary  to  group  A  β-hemolytic  Streptococcus.  She  was  treated  with  penicillin  and  nonsteroidal  anti-inflammatory  drugs  (NSAIDs)  and  was  advised  temporary  bed  rest.  She  experienced  complete  resolution  of  the  EN  within  4  weeks.
