The floor of the ulcer is similarhistologically to an abscess wall. Ulcers may be divided into: Phagedenic—rapidly spreading and destructive. Serpiginous—snake-like and irregular, healing on one side andprogressing on another. Fungous—in which excessive granulation tissue forms. Indolent—in which granulation tissue is slow in forming. Gangrenous—in which putrefaction is an added feature. Follicular—small in extent as in crypts or follicles of Fig. 24.—Tuberculous ulceration of the intestine. fStengel and Fox.) Specific—due to tuberculous, syphilitic or other infection.(Fig. 24. Peptic—due primarily to the digestive action of enzymes. V. Catarrhal Inflammation is inflammation of a mucous mem-brane, characterized by degeneration of epithelium (mucoid,fatty or necrotic) which is discharged with the abundant serousexudate upon the surface. The submucous tissue is infiltratedwith a more or less serous exudate. (See Fig. 25.) AVhen there are abundant leucocytes we have a purulent ormucopurulent catarrh. In chronic forms, productive processes lead to overgrowth ofconnective tissue, giving an appearance of hypertrophy of themucosa. Lateron. contraction of the fibrous tissue causes atro-phy. ATIOX 105 Follicular Inflammation are terms applied to swollen lymphfollicles, or in mucous glands
