Erythema nodosum leprosum – http://id.who.int/icd/entity/1678551661

Erythema nodosum leprosum is a necrotizing vasculitis involving small to medium-sized vessels of the deep dermis and subcutis. It is provoked by an immune complex-mediated response to release of mycobacterial antigens from effete bacilli in patients with multibacillary leprosy (lepromatous and borderline lepromatous), usually after initiation of treatment.
