CYSTIC GROWTHS. 203 tion,—the granular fatty matter of oil globules and granules mixed withbroken-up crystals, epithelial scales, and sometimes the products of fibri-nous exudation (Figs. 208, 210). Such is the general structure of theatheromatous encysted growths of various authors. /?- v- Lii-H -. a » • e ° » LJ1_-. Fig. 210. Fig. 211. Again, the fatty matter may be more or less lardaceous in character,and consists of beautiful round or oval cells, some of which are distinctlynucleated. Mixed with these may be a granular matter, combined withepithelial cells or their debris (Fig. 211.) At other times no distinctcells can be observed, only a granular or amorphous mass, the greaterpart of which is soluble in ether. This constitutes the steatomatous en-cysted growth (Fig. 209). 6. Many encysted growths contain hair and teeth. The hair is occa-sionally inserted into the walls of the cyst, at other times lies loose in it,mixed with the fatty or other contents. The hair has exactly the samestructure as the hairs in other parts of the body, having distinct bulbousroots. When attached they are surrounded by a follicle in the liningmembrane : when loose they have been evidently grown in follicles, andbeen afterwards separated. Their apices are frequently split up intoseveral fi
