Recurrent Cutaneous Eosinophilic Vasculitis: A Rare Entity

Recurrent cutaneous necrotizing eosinophilic vasculitis is a rare entity described by Chen et al. It has a benign course without any systemic involvement. However, often long-term treatment with systemic steroids is required. The exact etiopathogenesis remains unknown. We report a female patient, who presented with recurrent pruritic purpuric papules and plaques affecting different body parts of long duration. Disease was well controlled with low dose systemic steroids, but invariably recurred on its withdrawal. Histology revealed the features of eosinophilic vasculitis. Subsequent detailed evaluation ruled out systemic involvement, underlying diseases, and any precipitating factors. Hence, a diagnosis of recurrent cutaneous eosinophilic vasculitis was made. Patient showed excellent response to prednisolone, and on tapering the drug, it was found that she needed a maintenance dose of 5 mg/day. We did not come across any previous reports of recurrent cutaneous eosinophilic vasculitis from India.
