Dystrophic calcinosis cutis is defined as the abnormal deposition of insoluble calcium salts in dead or degenerated cutaneous tissues in the absence of abnormal serum calcium or phosphate concentrations. Although dystrophic calcification can occur in various diseases, its occurrence on a burn scar has rarely been reported in the dermatologic literature. Herein we describe two patients who presented with a solitary non-healing ulcer in a postburn scar, with histopathologic evidence of calcium deposition in the dermis. 相似文献

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. 相似文献

A 65-year-old Japanese female developed a nodule on the distal interphalangealjoint of her right thumb. She also had multiple telangiectasias on her face, oral mucosa, tongue, nasal mucosa and upper extremities. A lip biopsy showed irregularly dilated capillaries and venules lined by flat endothelial cells. The nodule in the right thumb was resected. Histopathology revealed calcium deposits in the dermis. This case was diagnosed as dystrophic calcinosis cutis within hereditary hemorrhagic telangiectasia. Ophthalmologic examination showed bilateral retinal vascular lesions with dilated and tortuous retinal venules. 相似文献
