Aplasia cutis congenita with congenital contracture of knee.

Aplasia cutis congenita is a rare developmental anomaly that most commonly involves vertex of the scalp and may be associated with other congenital anomalies. Although isolated congenital absence of skin and congenital knee contracture is known,, association of these two conditions is not reported. We report on a child with absence of skin of left lower limb with contracture of left knee at birth.
