title: [Skin sarcoidosis simulating necrobiosis lipoidica].
abstract: A patient who had had pulmonary sarcoidosis for 11 years developed multiple symmetrical lesions with ulcerations on the lower legs. The lesions showed the typical clinical picture of necrobiosis lipoidica and could not be differentiated histologically with certainty. Three years later persistent reddish plaques appeared on both arms, which allowed clinical and histological diagnosis of cutaneous sarcoidosis.
