Palmoplantar keratoderma associated with congenital heart disease.

We report the case of a 14-month-old boy suffering from total anomalous pulmonary venous connection (TAPVC) associated with congenital diffuse palmoplantar keratoderma (PPK). An association between TAPVC and PPK has not been described previously, but PPK has been reported in association with a variety of cardiac abnormalities. Given the low frequency of both conditions, a genetic link seems likely. It is therefore advisable for dermatologists to check for heart abnormalities in children with congenital PPK.
