 A variety of eponyms have been proposed for MEN 2B, such as Williams-Pollock syndrome, Gorlin-Vickers syndrome, and Wagenmann-Froboese syndrome.However, none ever gained sufficient traction to merit continued use, and they are no longer used in the medical literature.The prevalence of MEN2B is not well established, but has been derived from other epidemiological considerations as 1 in 600,000 to 1 in 4,000,000.
