Discoid lupus erythematosus

DLE may occasionally resolve spontaneously, but, if it is left untreated, most patients tend to have progressive lesions that spread to produce larger areas of scarring. With scalp involvement permanent scarring alopecia can result, which may be emotionally and psychologically disabling. Acute exacerbations may occur, particularly in spring and summer, most likely as a consequence of ultraviolet light exposure.
