Aglossia

 ( Congenital Disorders Of Digestive System ) 

Aglossia (aglossia congenita) is a congenital defect resulting in a partial development or complete absence of a tongue.

The first known case was reported in the early 18th century by a member of the prominent De Jussieu family in France and cases to this day remain rare.
