skin manifestations of PAN

Last reviewed 01/2018

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.
