A unique case of cutaneous calcinosis with transepidermal elimination

A case of cutaneous calcinosis with unique clinical and histological features which occurred on the cheek of a 14-year-old girl, is reported. Our case had no abnormal findings in laboratory data. Serum calcium and phosphate were normal, there was no underlying disease, and the possibility of self-inflicted dermatoses was denied. Transmission electron microscopy and X-ray microanalysis showed calcium and phosphate deposited around collagen fibers, which were eliminated from the epidermis.
