title: Lymphangioma circumscriptum of the tongue.
abstract: A case is reported of severe transient macroglossia after biopsy from the tongue in a 13-year-old boy who has had intermittent macroglossia since the age of 1 year as a result of extensive lymphangioma circumscriptum of the tongue. The acute lesions appear to result from haemorrhage into the lymphatic spaces following rupture of blood vessels in connective tissue septa and possibly secondary infection.
