Rare Aneurysmal Bone Cyst Presentation in the Orbit: A Systematic Review of the Literature with an Illustrative Case Report.

Objective: Aneurysmal bone cysts (ABCs) are benign but aggressive vascular lesions within bone. Orbital ABCs, though rare, are clinically significant due to the risk of debilitating symptoms such as vision loss.

Methods: Our systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed, Google Scholar, Embase, and SCOPUS databases to identify and assess primary articles exploring orbital ABC cases.

Yunis-Varon Syndrome.

Yunis-Varon syndrome is a rare autosomal recessive disorder with characteristic facial features and limb anomalies. We report a neonate born to consanguineously married normal parents with typical clinical and radiologic features of Yunis-Varon syndrome along with complete cleft lip and palate: an infrequent association. The family had two previous babies with similar features who died in infancy.
