PERFORATING NECROBIOSIS-LIPOIDICA - 2 CAS ES

Introduction: Perforating necrobiosis lipoidica is a rare clinical for m of necrobiosis lipoidica and is almost always associated with diabet es. Necrotized tissue is usually eliminated via transfollicular perfor ations. Case report: We report two cases of perforating necrobiosis li podica associated with type II diabetes mellitus. The characteristic c linical feature was the presence of keratotic plugs around the periphe ry of the lesions. Transfollicular perforation predominated in the fir st case. The second also presented epidermal perforation. Discussion: There have been only 6 cases of perforating necrobiosis lipoidica in t he literature. To our knowledge, this is the first case report of tran sepidermal elimination. We confirmed the constant association between this perforating type and diabetes mellitus.
