Angio-Fibromata begin as granulation tumours, and arethe result of proliferation of the elements of the vascular cells of the tunica adventitia also proliferate, and thus producea network of cellular strands. The same process takes place inthe endothelium, and the vascular \\alls increase in thickness,sometimes to such an extent that many of the vessels become* Archives of Otohg)/, vol. xi.
