In the last several years, amantadine has been increasingly prescribed for akinesia in Parkinson's disease and to combat fatigue associated with multiple sclerosis. Amantadine is a well-known medication involved in drug-induced livedo reticularis (LR), yet remains under-reported in the English literature. We describe 2 patients with amantadine livedo reticularis: one patient with multiple sclerosis had, previous to this eruption, tolerated 4 years of amantadine therapy without adverse reactions and another patient with Parkinson's disease who developed LR 1 month after starting amantadine.

When an understanding of pathogenesis exists, skin lesions that have the appearance of blood in the skin can provide insight into the mechanisms leading to a systemic process that results in cutaneous manifestations. Of the vascular disturbances of the skin that occur in critically ill patients, some result from a non-hemorrhagic process while occurs represent bleeding into the skin. The lesions of livedo, petechiae, purpura, and ecchymoses can be approached from such a perspective.

While the skin is a common target organ for sarcoidosis, cutaneous granulomatous vasculitis is rare among patients with sarcoidosis. Due to the lack of detailed studies on cutaneous sarcoid vasculitis, both dermatologists and pathologists remain unfamiliar with this rare but important vasculitic disorder. We clinicopathologically evaluated eight cases with biopsy-proven cutaneous vasculitis and cutaneous sarcoidosis and analyzed morphologic changes in the process of vasculitis for both small vessels and muscular vessels in detail.

Polyarteritis nodosa (PAN) is a rare systemic necrotizing vasculitis preferentially targeting medium-sized arteries. PAN has two clinical entities: systemic PAN (sPAN) and cutaneous PAN (cPAN). cPAN is a skin-limited vasculitis, while ulcerative cPAN often predicts a higher risk of recurrence and a worse prognosis.
