A new syndrome of "spondylo-epi-metaphyseal dysplasia: mixed type".

A new type of rare bone dysplasia is described, which shares some common features with spondylo-meta-epiphyseal dysplasia: short limb-abnormal calcification type and lethal metatropic dysplasia. Besides these features, the present case has some additional unusual features. Facial malformation was very obvious and of a different type. The nose and nares were completely flattened. Hypertrophied acetabular bones, round densities on the ilia, premature ossification of many epiphyses and carpal bones, curvilinear calcifications in some joints, fusion of the ischiopubic rami, calcification of many costal cartilages and thick sclerotic base of the skull were a few of the significant findings. On the basis of the clinical and radiological features, the condition has been named "spondylo-epi-metaphyseal dysplasia: mixed type".
