Glial choristoma of the tongue is an extremely rare developmental malformation. The authors report a case of a 5-month-old male baby with a congenital glial choristoma located on the posterior part of midline of the left dorsal tongue. Histological examination of the resected specimen revealed a poorly demarcated submucosal mass containing neuroglial tissue, scattered neuron, choroids plexus and ependyma. In addition to neuroglial tissue, a sheet of leptomeningeal tissue was observed more rarely in the case. The clinical and pathological characteristics of previous cases and their probable embryogenesis were also reviewed.
