BACKGROUND
Calcinosis cutis is classically described in patients presenting chronic renal failure with secondary hyperparathyroidism. There are three clinical types described in the literature: cutaneous necrosis (secondary to vascular calcification), panniculitis with calcification of the adipose tissue and necrosis of the skin and dermo-hypodermic calcinosis without necrosis usually called metastatic calcinosis. The latter can affect all tissues but skin involvement is rare.
METHODS
A case of calcinosis cutis is presented in a 50 years old woman with moderate secondary hyperparathyroidism and chronic renal failure caused by renal amyloidosis. She was referred by the renal unit to our service for erythematous, woody-hard, infiltrated plaques with petechial purpura satellite lesions, involving the flexural areas, that appeared within a few weeks.
CONCLUSIONS
This observation is original by the topography of the cutaneous lesions the involvement of the fexural areas is unusual and by the histologic aspect of pseudoxanthome elastic-like. We must notice that the hyperparathyroidism had always been very moderate (normal parathormonemia) compared to the rapid development of an important dermic calcinosis.
