Calcified cutaneous nodules on the heels of children: A complication of heel sticks as a neonate

We report the presence of calcified nodules on the heels secondary to heel sticks in healthy monozygotic twins in childhood. The subjects were born pr eterm at 34 weeks, The heels were normal at birth. While in the hospital, t hey underwent multiple heel sticks as a means of venesection, The wounds fa iled to heal normally and warty lesions developed. Calcified cutaneous nodu les secondary to heel sticks have been reported primarily in high-risk, pre term infants. There have also been two reports of their development in norm al healthy infants, To date, all reported lesions have been asymptomatic, w ith spontaneous resolution by 18-30 months. These cases indicate that such lesions can in fact be chronic, extending into childhood, when they may bec ome symptomatic. Dermatologists should therefore consider this diagnosis as a cause of warty, calcified nodules on the heel in childhood as well as in infants and in neonates.
