    invasion of their matrix. Their growth is usually slow, but they may attain an enormous size. Secondary Changes.—Of these the most common is rupture of the capillaries, haemorrhage, and the formation of sanguineous cysts ; this, however, is less frequent than in the sarcomata. The cells themselves may undergo mucoid or fatty degeneration, and thus be destroyed: this is usually accompanied by liquefaction of the inter- cellular substance. Yabieties.—The varieties of myxoma depend prin- cipally upon its combination with other growths. The most common is a combination with lijDoma. Combina- tions with sarcoma, enchondroma, and adenoma, are also frequently met with. Phtsical Chauacteus, &c.—The myxomata are of a pecuHar soft gelatiniform consistence, and of a pale greyish or reddish-white colour. Their cut surface yields a tenacious mucilaginous liquid, in which may be seen the cellular elements of the growth. They are most fre- quently met with in the later pei-iods of life. Growing from the sheaths of nerves, they constitute one variety of so-called neuroma. They may also grow fi-om the placenta, constituting the uterine hydatids. When situated in superficial parts they may become peduncu- lated. In the submucous tissue of the nose they consti- tute one form of nasal polypus. Clinical Chabacters.—Clinically the myxomata are for the most part benign growths. If completely removed they rarely recur. Sometimes, however, they exhibit malignant characters, and recur locally after removal. They probably never reproduce themselves in internal organs. In speaking of their malignancy their occasional association with sarcoma must be borne in mind.
