An infant who died in the perinatal period with the unusual association of trisomy 18 and cebocephaly is described. It is suggested that this association may be more common than is generally recognised because the majority of such infants are stillborn or live only briefly and often do not have chromosome studies performed.

This paper is part of the emerging field of Evolutionary Developmental Pathology, dedicated to study the links between normal and abnormal development, evolution and human pathologies. We analyzed the head musculoskeletal system of several 'natural mutant' newborn lambs displaying various degrees of abnormality, from mild defects to cebocephaly and to cyclopia, and compared them with humans. Interestingly, muscle defects are less marked than osteological ones, and contrarily to the latter they tend to display left-right assymetries.

Rationale: Holoprosencephaly is a structural malformation of the brain that results from the complete or incomplete noncleavage of the forebrain of the embryo into 2 hemispheres. We report a severe case of alobar holoprosencephaly diagnosed at 38 weeks, associated with cebocephaly, microcephaly, and craniosynostosis.
Patient Concern: The main knowledge added by this case is the late ultrasound diagnosis and chromosomal analysis that revealed a very rare abnormality (45X/46,XX/47,XX) with mosaicism at chromosome 18.

Background: The term holoprosencephaly was proposed by DeMyer and Zeman. It is a developmental defect of the embryonic forebrain with heterogeneous etiology including genetic and environmental factors. It is commonly associated with midfacial defects and has a spectrum of presentations.

We report a case of alobar holoprosencephaly (HPE) and cebocephaly associated with uncontrolled maternal type 1 (insulin-dependent) diabetes mellitus. Alobar HPE is the most severe form of HPE. Patients with cebocephaly have ocular hypotelorism and a proboscis with a single, blind-ended nostril.

According to the most recent scientific knowledge, the malformations caused by defective development of the anterior brain and midline mesodermal structures include cyclopia (synophthalmos), ethmocephaly, cebocephaly and arrhinencephaly. These severe forebrain lesions often are accompanied by severe systemic malformations, and affected infants rarely survive.
