Ellis-van Creveld syndrome (EVC) is a rare chondroectodermal dysplasia presenting several skeletal manifestations and congenital heart malformations. Polydactyly is the most frequent skeletal anomaly. The authors report two cases of EVC syndrome with different manifestations, which underwent surgical treatment for polydactyly.
