Arthrogryppsis Multiplex Congenita: Pathologic examination of three autopsy cases

ABSTRACT

Three autopsy cases of arthrogryposis multiplex congenita are studied. They were two deadborns and one neonatal death. All of them had characteristic abnormalities involving multiple joints. Neither primary myopathy nor abnormalities of anterior horn cells of the spinal cord were detected in our cases. However, two cases had minor central nervous system anomalies. All four cases showed pulmonary hypoplasia of varying degree. Two of three cases showed facial dysmorphism such as micrognathia and low set ears, and one showed cleft lip and palate. Ventricular septal defect, umbilical hernia and ureteral anomalies were also associated.
