A fairly common benign inflammatory disease of the skin and the lining of the mouth, which often gives rise to itching. There are small discrete raised areas of skin which at times coalesce into rough scaly patches. The raised areas are angular and have a flat shin surface of pink or violet hue.

Certain drugs may produce an identical eruption. The initial attack persists for weeks or months and may recur intermittently. Children rarely are affected.

The condition typically affects the wrists, arms, legs, and trunk, but is rarely seen on the face. Occasionally the lesions are widespread. The cause of the disease is unknown. Sedation may be necessary in sever cases, but usually all that is required is the application of a soothing lotion or hydrocortisone ointment.
