NECROBIOSIS LIPOIDICA - CLINICAL CASE

Abstract

Necrobiosis lipoidica is a rare, chronic, idiopathic granulomatous disorder of the skin, often associated with type 1 diabetes mellitus. Its exact etiology remains unknown; however, vascular disturbances involving immune complex deposition and microangiopathy are considered important contributing factors. Diagnosis is primarily clinical, although a skin biopsy may be performed to differentiate it from granuloma annulare, sarcoidosis, or necrobiotic xanthogranuloma.

Management includes topical or intralesional corticosteroids for active lesions, wound care, and surgical excision for ulcers. Ulceration and scarring are common complications, and lesions should be monitored over time. We report a clinical case that highlights the importance of clinical recognition, dermoscopy, and histopathologic confirmation of necrobiosis lipoidica in patients with diabetes mellitus, facilitating early intervention and prevention of complications.
