The brain malformation may cause the head itself to be enlarged or asymmetrical. Sebaceous nevus syndrome may result in eye tumors and the skull may be asymmetrical. It is also known as Organoid Nevus. Furthermore, if the ducts arising from the sebaceous glands are distorted or malformed, or if there are any pre-existing genetic ailments like Gardner's syndrome, basal cell nevus syndrome, these could also result in sebaceous cysts. The most common symptom of basal cell nevus syndrome is the development of basal cell carcinoma in adolescence or young adulthood.
