Achard Syndrome

Arachnodactyly, receding lower jaw, and joint laxity limited to the hands and feet are features. When Thursfield (1917-18) reviewed the literature on Marfan syndrome, he remarked that the skeletal picture in the cases described by Achard (1902) differed in that the skull was broad and brachycephalic with small mandible; although there was arachnodactyly, the body proportions were not altered and the patient was not excessively tall. Parish (1960) pictured a case. It is not clear what this condition represented or even that it is a distinct entity.
