Lupus may begin in two different ways. Either in the form of a purple spot, which is raised above the level of the skin and which has no definite limits but blends with the healthy parts; or as a slightly raised, moderately firm, darkred grain, sharply limited and about the size of a pinhead or millet seed. If the disease has begun in the shape of spots, the afflicted portions of the skin gradually swell during the process of the disease. Several isolated knots appear around which the disease spreads more and more. While the disease thus takes possession of greater area and developes new centers, a uniform scaling off of all knots begins. After prolonged existence, sometimes after short duration, decay and casting off of the epidermis in its entire thickness supercedes the scaling process, and suppuration transforms the ringworm into an ulcer covered by a dirty-brown rind and disagreeably colored serum. The ulcers of lupus are of various, generally irregular shape, the rims not hard, the ground flat and covered with purulent matter and decayed tissue; they are commonly surrounded by a faint reddish areola. These ulcers gradually become epulotic and form irregular, generally slightly protruding white scars in which new tubercles may appear. Lupus appears most frequently in the face and especially frequent on the nose. Sometimes its appearance is indicated only by an inflammation and swelling of the mucous membranes of the nose and at the same time a reddening of the epidermis. The nostrils are stopped up by a thin rind which, if torn off, is replaced by a thicker one below which an ulcer is formed that spreads with greater rapidity on the mucous membranes of the nose than on the external epidermis of the same. Sometimes the whole process on the nose is so rapid, that very often the physician is not called to the patient, before a large part of the wing of the nose or of the nasal epidermis is destroyed and deep ulcers have developed under the rind. New tubercles of lupus are commonly noticed to spring up on the margins of these ulcers; the cartilage as a rule resists the progress of the disease for a longer period and may be unhurt, while the skin on the wing of the nose may be completely destroyed. Frequently the process is extended to the mucous lining of the hard palate and to the gums. Lupus generally appears on the lips in the same manner as in the nose. The upper lip especially appears very much swollen and covered with ulcers after a prolonged existence of the affection. Sometimes even the aperture of the mouth itself is reduced in size by the development of ulcers and scars on the surrounding parts.
