Nevi, in general, may be either congenital or developmental. The most common intraoral type of nevus is the intramucosal nevus followed by the blue nevus. Pigmented fungiform papillae of the tongue was first described in 1905 and was suggested to be associated with endemic anemia. 5 After many cases were subsequently reported, PFPT was considered a common variant of the oral hyperpigmentation that is seen in individuals with intensely pigmented skin.
