Holoprosencephaly, a grave malformation during cleavage phase of brain development,
occurs in association with a variety of Clinical syndrome including chromosomal
aberration. Among chromosomal anomalies trisomy syndromes, particularly trisomy 18,
are often associated with holoprosencephaly. Triploidy with holoprosencephaly had also
been described. We report an autopsy case of incomplete triploidy with abnormal sex
chromosome, i.e., 63, XXY Our case showed a marked intrauterine growth retardation,
and postmortem examination revealed alobar holoprosencephaly. hypotelorism, bilateral
cleft palates and lips, flat nose, microstomia, lowset ears, congenital heart disease and
cystic kidney. The brain was microcephalic 5¡¿6 §¯ and was of pancake shape. there
was a large dorsal cyst. Olfactory tracts and bulbs were absent. The brain surface was
smooth, and only suggestive hippocampal fissure was noted. The basal ganglia and
thalami were fused in midline and the aqueductal origin was exposed. The brain stem
and cerebellum were unremarkable. Repeated karyotypings revealed 63, XXY
consistently. All 21 chromosomes showed trisomy except for D group. The sex
chromosome was XXY, and the genital tract and gonad were those of female. (Korean J
Pathol 1995; 29: 106¡­109)
