PURPOSE OF REVIEW: The present review will focus on recent publications in
cutaneous vasculitides.
RECENT FINDINGS: Some histopathological and clinical features, such as papillary
dermal edema, perivascular C3 deposition, clinically evident edema, and lesions
above the waist, may point out renal or gastrointestinal involvement in
Henoch-Schönlein purpura (HSP). HSP associated with familial Mediterranean fever
differs from typical isolated HSP by showing no deposits of IgA, much younger
age, and location of the lesions on the face or the trunk. Single-organ cutaneous
small vessel vasculitis is a more restricted entity than hypersensitivity
vasculitis and HSP. Because cutaneous polyarteritis nodosa and macular
lymphocytic arteritis share some clinicopathologic features, the question is
raised whether they are not two different entities. Several histopathological
features defining IgG4-related disease are found in granuloma faciale and
erythema elevatum diutinum, two localized chronic cutaneous vasculitis; however,
in a recent series no diagnostic criteria for IgG4-related disease was detected
in them.
SUMMARY: When a patient presents with skin lesions, in which necrotizing or
leukocytoclastic vascuitis is confirmed histologically, irrespective of the size
of the affected vessel, the possibility of systemic vasculitis, an infection,
medication, or a systemic disease such as systemic lupus erythematosus must be
searched before reaching definitive diagnosis.
