LUPUS (See also:Lat. lupus, See also:wolf) , a disease characterized by the formation in the skin or mucous membrane of small tubercles or nodules consisting of See also:cell growth which has an inclination to See also:retrograde See also:change, leading to ulceration and destruction of the tissues, and, if it heals, to the subsequent formation of permanent See also:white scars. Lupus vulgaris is most commonly seen in See also:early See also:life, and occurs chiefly on the See also:face, about the See also:nose, cheeks or ears. But it may also affect the See also:body or limbs. It first shows itself as small, slightly prominent, nodules covered with thin crusts or scabs. These may be absorbed and removed at one point whilst spreading at another. Their disappearance is followed by a permanent white cicatrix. The disease may be superficial, in which See also:case both the ulceration and the resulting scar are slight (lupus non-exedens); or the ulcerative See also:process may be deep and extensive, destroying a large portion of the nose or cheek, and leaving much disfigurement (lupus exedens). A milder See also:form, lupus erythematosus, occurs on the nose and adjacent portions of the cheeks in the form of red patches covered with thin scales, underneath which are seen the widened openings of the sebaceous ducts. With a See also:longitudinal patch on the nose and spreading symmetrical patches on each cheek the See also:appearance is usually that of a large butterfly. It is slow in disappearing, but does not leave a scar. Lupus is more frequently seen in See also:women than in men; it is connected with a tuberculous constitution. In the superficial variety the applica-tion of soothing ointments when there is much redness, and linear incisions, or scrapings with a See also:sharp See also:spoon, to destroy the increased See also:blood See also:supply, are often serviceable.

In the See also:

ordinary form the See also:local treatment is to remove the new See also:tissue growth by solid points of See also:caustic thrust into the tubercles to break them up, or by scraping with a sharp spoon. The See also:light-treatment has been successfully applied in See also:recent years. As medicines, See also:cod-See also:liver oil, See also:iron and See also:arsenic are useful. (E.
