    known by the fact that individual cells can be recognised, and by the absence of wavy tendinous fibrillae ; from the latter the dis¬ tinction depends on the facts that other types of tissues may occur in the sarcoma and that the growing edge is usually more or less embryonic in character, whilst a myoma is of the same structure throughout. Again, in a myoma the bloodvessels have distinct and definite walls, and in a sarcoma they are simply clefts or passages in the tumour substance. Myomata are met with in the uterus and prostate, and occasion¬ ally in the walls of the alimentary canal and in the ovary. Secondary changes sometimes occur, e.g.} mucoid softening, as in fibro-cystic disease of the uterus, calcification, ulceration with Fig. 31.—Ivory Exostosis growing from Frontal Sinus, and encroach¬ ing BOTH ON THE ORBIT AND THE CRANIAL CAVITY. (BLAND SUTTON.) (From specimen in the College of Surgeons’ Museum.) profuse haemorrhage, and possibly consequent septic inflammation, whilst malignant disease may supervene. For the characters of the prostatic myomata, see Chapter XXXVI. Tumours consisting of striped muscle fibres (Rhabdomyoma) have been described, but are exceedingly rare. Neuroma.—True Neuroma is seldom met with, only five un¬ doubted cases being on record. It is formed by a mass of newly- formed ganglion cells and nerve fibres, which may be medullated or not. In all but one case it involved the sympathetic system, and occurred in children or young people. The tumours may attain considerable dimensions, are often multiple, and may be quite soft, like a lipoma, or firm. They are insensitive and inno¬ cent, and may be freely removed. 9—2
