Even the tongues which, to the naked eye, appeared solid, were found to possess the same minute structure as the cavernous tongues, so that the opinion now generally prevails that in every case of macroglossia there is dilatation of the lymphatic vessels. In some tongues the dilatation does not produce sufficient alteration in the appearance of the cut tongue to be distinguished by the naked eye; in other tongues it produces a decided cavernous structure like that described by Virchow. In addition to the dilated lymphatics, the blood-vessels are also more numerous, and many of them are dilated, especially the smaller arteries, the coats of which are thickened. The connective tissue, especially around the dilated lymphatics, is hypertrophied and infiltrated with lymphoid cells, and Arnstein says that there is also adenoid tissue in the same parts of the tongue, very rich in lymphoid cells.
