Oculoectodermal syndrome (OES) is characterized by the association of epibulbar dermoids and aplasia cutis congenita. Affected individuals exhibit congenital scalp lesions which are atrophic, nonscarring, hairless regions that are often multiple and asymmetric in distribution, and may have associated hamartomas. Ectodermal changes include linear hyperpigmentation that may follow the lines of Blaschko and, rarely, epidermal nevus-like lesions. Epibulbar dermoids may be uni- or bilateral. Additional ocular anomalies such as skin tags of the upper eyelid and rarely optic nerve or retinal changes or microphthalmia can be present. Phenotypic expression is highly variable, and various other abnormalities have occasionally been reported, including growth failure, lymphedema, and cardiovascular defects, as well as neurodevelopmental symptoms such as developmental delay, epilepsy, learning difficulties, and behavioral abnormalities. Benign tumor-like lesions such as nonossifying fibromas of the long bones and giant cell granulomas of the jaws have repeatedly been observed and appear to be age-dependent, becoming a common manifestation in individuals aged 5 years or older (summary by Boppudi et al., 2016).

MalaCards based summary:
Oculoectodermal Syndrome, also known as aplasia cutis congenita with epibulbar dermoids, is related to encephalocraniocutaneous lipomatosis and lipomatosis. An important gene associated with Oculoectodermal Syndrome is KRAS (KRAS Proto-Oncogene, GTPase), and among its related pathways/superpathways are Activation of cAMP-Dependent PKA and Nervous system development. Affiliated tissues include skin and breast, and related phenotypes are agenesis of corpus callosum and aplasia/hypoplasia of the skin
