AB Sporotrichosis  is  a  fungal  skin  infection  caused  by  Sporothrix  schenckii,  an  organism  primarily  found  on  plants  and  flowers  and  in  soil.  The  problem  is  common  among  gardeners  and  florists.  It  also  affects  those  who  handle  animals,  since  the  fungus  may  inhabit  claws.  Infection  occurs  when  contaminated  thorns,  spines,  or  claws  penetrate  the  victim’s  skin.  After  an  average  incubation  period  of  3  weeks,  localized  infections  become  apparent.  “Fixed”  cutaneous  infections  are  localized  to  the  inoculation  site  and  are  manifest  as  2-  to  4-mm  papules  or  nodules.  They  may  ulcerate  or  become  surrounded  by  raised  erythema.  They  are  typically  painless.  Progression  to  lymphocutaneous  infections  occurs  in  about  70%  of  cases.  Patients  present  with  a  nodule  at  the  site  of  penetration,  with  appearance  of  subcutaneous  nodules  and  skip  areas  along  lymphatic  tracks  later.  The  lesions  may  wax  and  wane  over  months  to  years.  Patients  with  cutaneous  sporotrichosis  typically  lack  systemic  symptoms.
