Definition / general
  • Rare fibrosing disorder with scleroderma-like induration of distal extremities
  • Diffuse fasciitis with fibrosis, eosinophilia and inflammation of skin, subcutaneous tissue and fascia
  • Not a WHO diagnosis
  • First described by Shulman (Trans Assoc Am Physicians 1975;88:70) [also called Shulman syndrome]
  • Mean age 50 years, 75% women
  • Eosinophilic-myalgia syndrome is different, and is associated with contaminated L-tryptophan, myalgia and neuritis (Hum Pathol 1992;23:429)
  • Shulman's syndrome tends to involve the subcutis alone and the eosinophilia-myalgia syndrome tends to be a pancutaneous-subcutaneous process (eMedicine, J Am Acad Dermatol 1992;26:95)
  • Presence of morphea-like skin lesions is associated with residual fibrosis (Clin Rheumatol 2007;26:1445)
