Skin manifestations of PAN

Authoring team

The skin is involved in PAN in 20-50% of cases.

The dermatological manifestations of PAN include:

  • subcutaneous nodules
  • skin necrosis
  • livedo reticularis
  • erythema multiforme
  • erythema nodosum
  • splinter haemorrhages

A relatively benign variant of PAN primarily involves the skin leaving the viscera unaffected. This "livedo with nodules" is treated in the same manner as true PAN with a better prognosis.
