Oculoectodermal syndrome

Definition

A rare ectodermal dysplasia syndrome characterized by aplasia cutis congenita and epibulbar dermoids. Affected individuals present mostly with multiple, asymmetrically distributed, hairless, non scarring, atrophic, congenital scalp lesions and unilateral or bilateral epibulbar dermoids with or without other ocular anomalies (including strabismus, nystagmus, microcornea, and microphthalmia). Eyelid coloboma, acrochordons, linear/cutaneous hyperpigmentation, mostly following Blaschko lines, can also be present. Giant cell granulomas of the jaws and nonossifying fibromas of the long bones are commonly observed in individuals starting from 5 years old. Additional and variable clinical features including growth failure, neurodevelopmental delay, epilepsy, learning difficulties, behavioral abnormalities, lymphedema, macrocephaly, cardiovascular defects, facial asymmetry and mild dysmorphism were reported in some patients.
