Swelling finger revealing systemic sarcoidosis. A case report

Abstract

Soft  tissue  localized  sarcoidosis  is  rarely  reported  in  the  literature  as  well  as  associatedcutaneous  vasculitis. We present  the case of a  34  year  old  patient  with a history  of a swelling in the distal  left index finger  phalanx evolving since  1 month  who  was  admitted for a  macular non  pruritic rash  of  his  legs.  Laboratory  findings  and  radiological  investigations  have  guided  the  diagnosis  of systemic  sarcoidosis  which  was  confirmed  by  finger  biopsy.  Cutaneous  biopsy  revealed  associated vasculitis. The aim of this case report is to highlight that in case of progressive swelling in soft tissue associated to cutaneous vasculitis, systemic sarcoidosis is a possible differential diagnosis. Biological and radiological work out may guide the diagnosis and biopsy will confirm it
