Squamous cell carcinoma arising in ulcerated necrobiosis lipoidica diabeticorum

© 2013 The Authors International Wound Journal © 2013 Medicalhelplines.com Inc and John Wiley & Sons LtdUlceration constitutes the main complication of necrobiosis lipoidica (NL) and usually occurs after trauma. Ulcerated NL predisposes patients to infections and very rarely is associated with malignant transformation, mainly to squamous cell carcinoma (SCC). We describe the case of a 68-year-old Caucasian male diagnosed with disseminated NL associated with type 2 diabetes mellitus (DM), presenting a SCC on an ulcerated plaque of NL located on the left forearm and chronic osteomyelitis of the radius.
