The tubular adenomata resemble the tubular glands, the epithe-lium of this variety differing from that of the acinous in beingmore or less columnar. They are most common in the mucousmembrane of the intestine, where they form papillary or polypoidgrowths. Both varieties are distinguished from carcinoma, in that theepithelium does not penetrate the basement membrane and invadethe connective tissue. Usual seats.—The acinous occur in the mamma (where theyare generally of the adeno-fibromatous form), the lip, the prostate,the thyroid, parotid, and lachrymal glands, and the sebaceousglands of the skin. The tubular occur in the intestine, especiallythe rectum. Secondary changes.—Cystic degeneration consequent uponmucoid softening, and fatty degeneration of the epithelum.
