REPORT OF A CASE
A 14-year-old immunocompetent boy who had been receiving growth hormone therapy for 2 years presented with a slowly progressing papule on the gluteal fold that had appeared a few months earlier. Physical examination revealed a smooth, firm, skin-colored, exophytic papule, situated more than 2.5 cm from the anal verge, measuring 0.5 cm in diameter. The lesion was excised, and microscopic examination showed irregular deep-blue basophilic masses. A diagnosis of traumatic or idiopathic cutaneous calcinosis was made. A complete serum analysis demonstrated no abnormalities, and there was no evidence of autoimmune disease or metastatic calcification.
After 1 year, the lesion recurred as a 0.8-cm nodule with a gelatinlike consistency (Figure 1). It was totally excised and stained with hematoxylin-eosin (Figure 2) and von Kossa technique (Figure 3).
