Case of dystrophic calcinosis cutis in epidermal cyst arising from verrucous epidermal nevus

Abstract

Dystrophic calcinosis cutis is diagnosed when calcium is deposited into previously damaged tissue by connective tissue disease, panniculitis, pseudoxanthoma elasticum or trauma. We report a case of dystrophic calcinosis cutis arising from the lesion of an epidermal cyst on the verrucous epidermal nevus. A 20-year-old woman presented with a polypoid pinkish tumor on a brownish, verrucous plaque. Histopathological findings of the pinkish tumor showed calcium deposits as amorphous, basophilic material lining the true epidermis in the upper dermis, which were compatible with dystrophic calcinosis cutis and the plaque was diagnosed as a verrucous epidermal nevus.

Multiple Scattered and Small Lesions of Lower Limbs: Idiopathic Calcinosis Cutis: A Case Report

“…Lesions without vascular involvement are divided into small scattered, nodular, tumoral and widespread. Calciphylaxis was the only example with vascular involvement 2 . In our case, the lesions were small scattered depositions of calcification within subcutaneous tissue.…”
