Clinical and pathologic manifestations of necrobiosis lipoidica-like skin involvement in sarcoidosis

Necrobiosis lipoidica dibeticum (NLD) is a granulomatous skin disease mostly associated with diabetes mellitus. NLD has been reported in patients with other systemic disease. Also, the lesions of NLD may be clinically, and sometimes even histologically indistinguishable from other inflammatory skin lesions. We described three patients with established diagnosis of sarcoidosis that developed skin lesions consistent with NLD. The association of NLD-like skin lesion in sarcoidosis is not widely appreciated. The subject of NLD and sarcoidosis is reviewed. (C) 2007 Published by Elsevier Masson SAS.
