Two autopsy cases of D_1-trisomy syndrome were reported. In the family history short stature of the mother was characteristic. The pathological characteristics in both cases were arhinencephalia, polydactylia, facial cleft, cardiovascular anomalies, dysplastic cerebellum, umbilical hernia, Meckel's diverticulum, common mesentery, poor ossification of cranial bones, and tendency of cyst formation in the thyroid and kidney. Several significant findings were observed in the two cases under study, but these varying features could not be evaluated at present.
