Pain ismore severe than in other tuberculous troubles Lupus Vulgaeis Lupus vulgaris first shows itself as several brownish-red spots, usually on the cheek or some part of the face orhands. The spots become nodules of granular tissue, grad-ually increasing in number, and extending in every direc-tion, until eventually several may coalesce, constituting onelarge tubercle. The nodules are slightly raised above the. Fig. 60.—Tuberculosis Cutis. (Dr. Geo. C. Johnston.) skin for a time, when they have a semi-transparent apple-jelly-like appearance. The liquid resulting from the coal-escence may be absorbed, and the center collapse and cica-trize, leaving a pit around which the tuberculous processextends to surrounding structures. Not infrequently theulceration extends through the skin, when there is presentthe usual tuberculous ulcer. The infection extends to thedeeper structures, even to the muscles and periosteum, andfinally to the bone, when left untreated. It most frequentlyattacks the exposed parts of the body, such as the face andthe backs of the hands. Etiology.—The infection of the skin, mucous membrane,or glands, enters through the glandular structure by in-oculation with the tubercle bacillus. It is most common inchildren, and is not hereditary except in rare instances. TUBERCTTLOSIS OF THE FACE 211 Pa
