In 1940, Ellis and van Creveld defined a syndrome they referred to as chondro-ectodermal dysplasia. This autosomal recessive condition, now usually referred to as Ellis-van Creveld syndrome (EVC), comprises bilateral postaxial polydactyly, a chondrodysplasia, characterized by shortness of limbs, and ectodermal dysplasia. Congenital heart defects are also common. There are many reports in medical literature describing affected newborns and even, older children. Here, we report the clinical, radiological and histological findings in a 15-week-old affected fetus. The diagnosis of Ellis-van Creveld syndrome in this fetus is based on a positive family history (an affected sib) and shortness of long bones as well as hexadactyly diagnosed by prenatal ultrasonography. On post-mortem examination, bilateral postaxial hexadactyly and symmetrical shortness of the long bones was noted. Histologically, there was too short a zone of cartilagineous columns in the metaphyses, a reduced number of chondrocytes and an irregularly structured spongiosa within the ossification zone. In addition, the fetus was found to have an atrio-ventricular canal. This heart defect is presumably rare in this syndrome. Other characteristic features such as small and dysplastic nails, sparse hair and abnormalities of the teeth were, of course, not yet present in this early developmental stage. In addition to EVC, the fetus had a 47,XXY chromosome constitution.
