Congenital Gaucher disease with nonimmune hydrops/erythroblastosis, infantile arterial calcification, and neonatal hepatitis/fibrosis. Clinicopathologic report with enzymatic and genetic analysis.

The findings in a stillborn female fetus of 31 weeks' gestation with congenital Gaucher disease, nonimmune hydrops/erythroblastosis, infantile arterial calcification, and neonatal hepatitis/fibrosis are presented, the first report of this complete constellation. Prior reports describe two similar patients. One lacked the hepatocellular features of giant cell hepatitis although manifesting hepatic fibrosis; the second lacked hepatic pathology.

Parietal bone agenesis with gracile bones and splenic hypoplasia/aplasia: clinico-pathologic report and differential diagnosis with review of cranio-gracile bone syndromes, "osteocraniostenosis" and Kleeblattschädel.

The findings in a newborn male with agenesis of parietal bones, gracile long bones, and hypoplasia of the spleen are presented. Although parietal agenesis is unique, the findings are compatible with 18 previously reported cases characterized by cranial hypomineralization, Kleeblatschädel, gracile bones, and splenic aplasia/hypoplasia, the nomenclature for which has been descriptive: gracile bone disorders, "osteocraniostenosis," "osteocraniosplenic syndrome." The term "osteocraniostenosis" may be inappropriate in that craniostenosis has been infrequently reported, a feature also of importance with respect to the pathogenesis of the Kleeblatschädel.

Osteocraniostenosis-hypomineralized skull with gracile long bones and splenic hypoplasia. Four new cases with distinctive chondro-osseous morphology.

Osteocraniostenosis is a severe skeletal dysplasia characterized by a hypomineralized skull that has been previously described as kleeblattschädel (cloverleaf skull) and overtubulated long bones. Dysmorphic facial features include a short nose, short philtrum, and a small, inverted V-shaped mouth. Splenic a/hypoplasia is a constant finding.
