A Case of Dystrophic Calcinosis Cutis Arising from the Lesion of Clear Cell Syringoma / 대한피부과학회지

ABSTRACT

Dystrophic calcinosis cutis is diagnosed, when calcium is deposited in the 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 clear cell syringoma. A 73-year-old woman presented with asymptomatic, multiple, skin-colored to whitish flat papules on the forehead. A punch biopsy specimen revealed amorphous basophilic materials in the upper dermis, as well as a large number of nests of clear cells in the middle dermis.
