Lymphangioma of the tongue: report of case.

Lymphangiomas are benign tumors of the lymphatic vessels, usually found in children. Lymphangiomas, however, may be misdiagnosed and in the absence of treatment may increase in size, producing macroglossia, swallowing and speech interferences, and respiratory difficulty. The size and isolated location of the lesion in the midline of the tongue reported here are unusual; few similar cases have been reported in the literature. Complete surgical excision provided not only removal of the lesion, but allowed normal recontouring of the tongue.
