Phakomatoses are a group of genetic and acquired disorders involving spots or tumors affecting the skin, brain, and other parts of the body. An ancient Greek statuette from 323-31 BC depicts a man with multiple smooth nodules representing neurofibromas. Quasimodo from The Hunchback of Notre Dame is speculated to have suffered from neurofibromatosis type 1 due to his hunched appearance. The term phakomatoses was coined by the Dutch ophthalmologist Jan van der Hoeve in the early 20th century to collectively describe these types of disorders.
