A case report of glial choristoma of the tongue

Glial Heterotopia in ENT-Two Case Reports and Review of Literature

The purpose of presenting these case reports is to highlight the occurrence of heterotopic glial tissue of the tongue and nose in children. So far, literature review has revealed few case reports of such lesions in neonates, but our patients presented with this unique lesion at the age of two and a half years and 3 years. This is a rare congenital anomaly in the tongue, which can mimic a lingual thyroid, teratoma, dermoid cyst etc. Surgical excision is mandatory when the lesion causes obstructive symptoms. The authors discuss the problems in diagnosis, pathology and management and review the literature.

Glial choristoma of the tongue: report of a case and review of the literature

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.
