Congenital macroglossal angiodysplasia ("Lymphangioendotheliomatosis").

Author information

Faculty of Dentistry, University of Jordan, Amman, Jordan.


A case of congenital lingual angiodysplasia with macroglossia in a 5-year-old girl is presented. A diffusely enlarged tongue was present at birth and continued to grow as the child aged. It was accompanied by impaired speech, difficulty in eating and breathing, and sleep apnea, necessitating surgical intervention. The fundamental lesion represents a complex vascular malformation of the lymphangioma-hemangioma type, involving extensively the deep musculature of the tongue. Multifocal and multicentric cavernous lymphangioma-like and hemangioma-like areas merge with benign angioendotheliomatous-like foci in a background of variable muscle degeneration and marked fibrosis. Neither a borderline nor an overtly malignant vasoformative neoplasm was present. Because of its distinctively widespread, multicentric intramuscular distribution, this lesion may be construed as a diffuse variant of lingual lymphangioma-hemangioma malformation, closely resembling a previously described case of macroglossal lymphangioendotheliomatosis.
