    ACNEMIA—ACOGNOSIA. nenmssschlag ; I. Pinna acne ; Arab. Abedsamen^ Bad'^chenan!) Retention of the secretion of the sebaceous glands of the skin, with secondary in- flammation and deposit in them and in the hair- follicles. It appears in the form of red conical or hemispherical elevations or nodules, varying in size from hemp seeds to beans; some solid, otiiers filled with pus; mostly distinct, but occasionally arranged in groups or in lines; found everywhere except upon the palms and soles, but chiefly aff'ectirig the skin of the face, chest, and back, and in the majority of cases occurring in young persons. The disease appears to be due to the occlusion of the orifice of the hair-folKcles or of the ducts of the sebaceous glands opening into them. The retained secretion then becomes a source of irritation and inflammation, and sup- puration in and around the hair sac and its ap- pendages follows. I'he treatment consists in the use of baths and friction ^with various kinds of soap, the application of weak aqueous or alcoholic solutions of corrosive sublimate, alkaline lotions, or weak sulphur ointment, and appropriate general and hygienic treatment. A. artificia'lls. Acne produced by arti- ficial irritants, such as iodides and bromides, when taken internally, and by tar applied externally. iA.. atrophica. A form in which the pustules are succeeded by atrophy of the structures aflfected. A.m cachectlco'rum. A form occurring in cachectic and scrofulous persons. It occurs on the limbs, as well as in other parts, each papule being surrounded by a livid border. £L, cilia'ris. Acne occurring at the edges of the eyelids. jflL. dissemina'ta. A term for the ordinary form of acne. A., firontalis. A synonym of Acne varioli- formis, from its occurrence on the forehead. £Lm horde'olans. A form of ordinary acne in which the papules, being ranged so close to each other, lose their rounded form and assume the shape of a grain of barley. A. hypertroph'ica. A form in which the pustules are succeeded by an hypertrophied con- dition of the parts affected. It is a sequel of Acne rosacea. The skin becomes reddish or purple, uneven, and oily; the hypertrophy of connective tissue and coriurn sometimes produces small sessile or pedunculated growths. ^ A. Indura'ta. A form of ordinary acne in which the papules obtain a large size, and are hard and non-pustular in appearance. A. menta'grra. A synonym of Sycosis, A. molluscoi'da. A synonym of MoUus- cum. A. of the throat. A synonym of Folli- cular pharyngitis. A. puncta'ta. That form of simple acne in which small red papules surmount a comedo, and rise slightly above the level of the skin. A. pustulo'sa. A condition of the ordinary form of acne in which there is more or less pus. A. rosa'cea. {Gutta rosea, bacchia; F. couperose ; Gr. das kupfrige Gesicht, Kupferhan- del, Kupferrose.) Attacks the face and scalp alone, and is characterised by an intense redden- ing of the skin, due to an injection of the blood- vessels without much swelling or tension. The serpentine vascular lines, the blood in which may be momentarily driven out by pressure, are most abundant and evident on the sides and bridge of the nose. This condition forms a ground on which develop protuberances of variable size and firm consistence, but without any purulent contents. An obstinate aflection occurring cliiefly in youth and in advanced age, and owing to the great hypertrophy of the skin of the nose occasioning great disfigurement. Acne rosacea never leads to ulceration, nor does the disease extend deeper than the skin. The treatment in the slighter cases consists in the application of sulphur in soap, ointment, or solu- tion; iodo-chloride of mercury ; solution of cor- rosive sublimate; in severer cases, incisions, and subsequent brushing over with perchloride of ix'on, touching the apices with acid nitrate of mercury ; and, in the worst form, removal has even been advised. A. seba'cea. A synonym of Sehorrhcea. A. sim'plex. A term for the ordinary form of acne. A. strophulo'sa. Also called Strophulus albus.
