The spaces not only undergo L YMPHANGIOMA. 463 cystic dilatation, but are enlarged by coalescence. In some cases hyper-plasia of the other tissues also takes place. Cystic lymphangioma differs from the cavernous variety only in thatthe individual separate spaces arising from new and dilated lymph-channels possess forms which correspond with their origin: they aremore or less globular in shape, corresponding in this respect with therosary-like appearance of the lymphatic vessels during the early stagesof the growth of the tumor. Cysts of large size are produced by theconfluence of numerous smaller spaces. The cystic variety is moreprone to progressive growth than the cavernous; in this respect thedist
