Multiple discharging sinuses with disseminated dactylitis.

A 21-day-old male infant presented with swelling over left upper limb for 3 days. Examination revealed a firm swelling of 3×4 cms over the proximal ventral aspect of left forearm and linear swellings over the medial aspect of left upper arm (Fig. 1(a)). Systemic examination and routine blood workup was normal. Ultrasound and X-ray of the swelling revealed subcutaneous calcification (Fig. 1(b)). This baby had asphyxia at birth, developed seizures and hypocalcemia on 2nd day of age, hence was treated with 10% calcium gluconate intravenously for 4 days and discharged with oral calcium supplementation. A diagnosis of iatrogenic calcinosis cutis was made.
