A 47-year-old female, known to be suffereing from systemic sclerosis since the past six years, presented with indurated plaques over thighs, buttocks [Figure - 1], and nodular swellings on elbows with chalky white discharge, since five months. Cutaneous examination showed proximal scleroderma, sclerodermoid facies, telangiectasia, salt–pepper pigmentation, and sclerodactyly. Detailed workup including serum calcium levels were normal (9.6 mg/dl). Anti-nuclear antibodies (1:320, indirect immunofluorescence) and anti-Scl70 were positive. X-ray (pelvis/lower limbs) showed diffuse subcutaneous calcification [Figure - 2]. Biopsy from the thigh confirmed subcutaneous calcium deposits. Extensive diffuse calcification (calcinosis cutis universalis) is common in dermatomyositis and infrequently reported in systemic sclerosis.
