CORN (fromm See also:Lat. corms, See also:horn)  , in See also:pathology (technically davus), a localized outgrowth of the epidermic layer of the skin, most 'commonly of the toe, with a central ingrowth of a hard horny plug . The underlying papillae are atrophied, causing a See also:cup-shaped hollow, whilst the surrounding papillae are hypertrophied . The See also:condition is mainly caused by badly fitting boots, though any undue pressure, of insufficient See also:power to give rise to ulceration, may be the cause of a See also:corn . Corns may be hard or soft . The hard corn usually occurs on one of the toes, is a more or less conical swelling and may be extremely painful at times . If suppuration occurs around the corn, it is See also:apt to burrow, and if unattended to may give rise to See also:arthritis or even See also:necrosis . The best treatment is to soften the corn with hot See also:water, See also:pare it very carefully with a See also:sharp See also:knife, and then paint it with a See also:solution of salicylic See also:acid in See also:collodion . The See also:painting must be repeated three times a See also:day for a See also:week or ten days . The soft corn occurs between the toes and is usually a more painful condition . Owing to the absorption of sweat its See also:surface may become See also:white and sodden in See also:appearance . The treatment is much the same, but See also:spirits of camphor should be painted on each See also:night, and a layer of See also:cotton See also:wool placed between the toes during the daytime .
