AB Hidradenitis  suppurativa  (HS)  most  commonly  affects  obese,  postpubertal  individuals  with  a  genetic  predisposition.  This  unremitting  disease  involves  intertriginous  sites:  axillae,  inguinal  folds,  gluteal  fold,  perianal  area,  and  inframammary  folds.  Lesions  begin  with  erythematous  nodules  that  become  tender  and  fluctuant.  The  sterile  abscess  ruptures  with  a  suppurative  discharge,  and  multiple  abscesses  can  eventuate  into  sinus  tracts  and/or  fistulae.  HS  is  primarily  a  noninfectious,  inflammatory  response  to  the  hair  follicle;  however,  secondary  infections  are  common.  Severe  hypertrophic  scar  formation  may  be  dramatic  and  disfiguring.  In  addition,  chronic  discharge  is  difficult  to  control  and  commonly  malodorous.  The  differential  diagnosis  includes  bacterial  furunculosis,  granuloma  inguinale,  mycetoma,  cutaneous  tuberculosis,  and  fistulas  associated  with  inflammatory  bowel  disease.
