vasculitis with secondary systemic involvement; or a cutaneous manifestation of a systemic vasculitis.
classifications of vasculitis
- small vessel (leukocytoclastic vasculitis)
- medium vessel: polyarteritis nodosa
- large vessel: giant cell temrporal arteritis, takayasu’s arteritis
which type of vasculitis more associated wtih cutaenous involvemnet?
small and medium vasculitis
Vasculitis secondary to medications is usually a small vessel vasculitis known as a
____ ____ (LCV) because of the predominance of ___ on pathology
Vasculitis secondary to medications is usually a small vessel vasculitis known as a
leukocytoclastic vasculitis (LCV) because of the predominance of neutrophils on pathology
morphology?
purpuric papules that are non-blanching, often favoring the lower legs. Lesions may be asymptomatic or painful or pruritic. Coalescing lesions will show skin
necrosis often with central pustulation.
approach to LCV
complete history and physical examination to identify likely etiology and possible extracuteanous oragn system involvement
- skin biopsy looking for immune complexs
- blood worka dn look for internal organ involvement
- discontinuation if medicine is a culpret.
what types of medications can cause cutaneous manifestations of small vessel vasculitis
allopurinol, sulfa-drugs, penicillin and anti-convulsants.
treatment for cutaneous involvement in vasculitis
conservative unless significant cutaneous necrosis is imminent.
Extracutaneous involvement is treated with oral corticosteroids and a steroid sparing immunosuppressive agent may be needed.
