The diagnosis and treatment of encysted growth belong to thespecial pathology of each organ affected by them. It need only bementioned here that a knowledge of the structure of these tumors isnot unimportant, as an examination of the fluid discharged from themfrequently enables us to speak with certainty regarding their nature. Glandular Growths.—Adenoma. Glandular growths are essentially hypertrophies of gland texture, inthe same manner that fibrous or fatty growths are an increase of fibrous. Fig. 218. or fatty tissues. But the structure of a gland is compound, and embracestwo kinds of growth. Strictly speaking, the growths are fibro-epithelial,but of a kind so peculiar as to warrant Lebert and Birkett in constitut-ing them into separate groups. Fig. 218.
