Recurrent cutaneous eosinophilic vasculitis characterized by annular purpuric lesions: A case report.

A 71-year-old woman presented with a persistent, intensely pruritic cutaneous eruption localized on the palmoplantar regions, lips and palate. The histological findings allowed to make the diagnosis of recurrent cutaneous eosinophilic vasculitis, a very rare cutaneous vasculitis characterized clinically by multiple erythematous or purpuric erythematous papules or plaques or angioedema with a relapsing course in the absence of systemic involvement and histologically by a necrotizing vasculitis of the dermal small vessels with a dominant eosinophilic infiltration. The patient was treated with oral methylprednisolone and pentoxifylline which led to a rapid resolution of the cutaneous lesions.
