Schinzel-Giedion syndrome: report of two sibs.

We report on two further cases, a sister and a brother, with Schinzel-Giedion syndrome. Both presented the following manifestations: "coarse face" with midface retraction, agenesis of corpus callosum, bilateral hydronephrosis, and typical skeletal anomalies. Patient 1 had a malignant sacrococcygeal teratoma. This is the third case of malignancy in this syndrome. Patient 2 died shortly after birth.
