Organoid nevus syndrome is characterized by cutaneous sebaceous nevus (nevus sebaceous of Jadassohn), seizures, mental retardation, epibulbar choristomas, and occasionally other systemic abnormalities.1,2 The lesion occurs most often on the scalp and retroauricular area and occasionally on the neck and trunk.3 Organoid nevus syndrome shares similarities with oculoneurocutaneous syndromes, or phakomatoses, and has been also called the linear nevus sebaceous syndrome.1,2 Ocular manifestations are present in up to 50% of patients and include epibulbar choristoma, posterior scleral cartilage, and coloboma of the eyelid, iris, ciliary body, retina, and optic disc.1,2
