Some neuro-fibromata consist of cords with nodular thick-enings and twined in a tendril-like manner, and these are calledplexiform neuromata. With regard to the so-called amputation neuroma, a tumour whichsometimes forms in amputation stumps, it may be counted amongst 84 TUMOURS OR NEW-FORMATIONS the true neuromata, inasmuch as it is composed of newly-formed nervefibres, which are developed from the old axis-cylinders by a process ofdivision, and grow into the cicatricial tissue on the surface left by Fig. 28.—Small Neuro-fibroma of the Skin, x 77.

Angioma.—This form of tumour consists in great part ofvessels or of a kind of tissue (cavernous tissue) nearly related as the vessels and vascular cavities contain blood orlymph, we speak of a limmatangioma or a lym-pliangioma. A further distinction is made between simple and cavernousangioinata. The simple h?ematangioma or teleangiectasis is com-posed of very numerous capillaries and veins, which may presentmultiple circumscribed dilatations of globular, spindle, or cylindricalform, or may have a gre
