Lymphangioma of the Dorsal Tongue

Lymphangioma of the Dorsal Tongue:

Abstract

Lymphangiomas are rare, congenital malformations of the lymphatic system which have a marked predilection for the head and neck. In this region, they most commonly occur on the dorsum of the tongue, followed by the lips, buccal mucosa, soft palate, and floor of the mouth. Lymphangiomas of the tongue are commonly present at birth; however, they may go unnoticed until after eruption of the dentition or even puberty. They may present as a defined mass or as macroglossia with impaired speech, difficulty in mastication, and, in extreme cases, airway obstruction. Clinically, lymphagiomas of the tongue are characterized by clusters of pebbly, vesicle-like nodules. A benign proliferation of lymphatic vessels is identified histologically. A classic case of a lymphangioma of the dorsal tongue is presented.
