Ellis-Van Creveld syndrome. Report of two cases.

Ellis-van Creveld syndrome (EVC) or chondroectodermal dysplasia, a rare autosomal recessive disorder, is a tetrad of chondrodysplasia, ectodermal dysplasia, polydactyly, and congenital heart disease, of which chondrodystrophy of the tubular bones is the most common feature, while central nervous system (CNS) and urinary tract anomalies are some of its rarer associations. This report describes EVC syndrome in two sisters of Indian origin, ages 8 and 6 years, the products of nonrelated, unaffected parents. The patients had chondrodysplasia of tubular bones resulting in disproportionate dwarfism, polydactyly, severely dystrophic nails, partially absent teeth, and short and bound-down upper lips with multiple frenulae. Other features noted in the girls were syndactyly and mild mitral regurgitation. All four of the classic features of EVC syndrome were present in patient 1 and three in patient 2. Additional findings were ichthyosis and plantar keratoderma in the former and absent clavicles in the latter, which have not been reported previously. The importance of prenatal diagnosis of EVC is stressed and a multidisciplinary approach for the management of these patients is highlighted.
