Cuta,neous periarteritis nodosa is a distinctive clinical entity that lacks the visceral manifestations of systemic periarteritis nodosa and follows a benign, chronic and relasping course. We experienced a 54-year-old male who had seven years history of
multiple, recurrent and painful subcutaneous nodules of both shins, many of which had ulcerated one month ago. Skin biopsy specimen from an inflxmmatory nodule showed neutrophilic vasculitis in the upper dermis and panarteritis of small and mediutn sized arterities in subcutiea.
