title: Arthrogryposis multiplex congenita, Pena-Shokeir phenotype, with gastroschisis and agenesis of the leg.
abstract: A young mother had a stillborn infant at 33 weeks' gestation, the pregnancy complicated by polyhydramnios. The parents were unrelated, healthy, and both had a normal karyotype. The infant had multiple malformations such as ankylosis, facial anomalies, and pulmonary hypoplasia. A severe gastroschisis and agenesis of the right leg were also present. The neuropathologic findings were those of marked atrophy of anterior horn motor cells in the spinal cord and neurogenic muscle atrophy. This is a case of Pena-Shokeir syndrome with two additional features: gastroschisis and agenesis of the right leg. This syndrome represents a lethal form of arthrogryposis multiplex congenita, and the essential neuropathologic findings are marked reduction in the number of spinal motor cells and neurogenic muscle atrophy.
