Lupus erythematosus has no papules, tubercles or ulceration.
There may be but four or five of these papules; rarely are there more than twenty.
It causes much irritation, with the eruption of papules or vesicles and the formation of sores and scabs.
Sometimes the papules are capped with a small vesicle (vesicular urticaria).
The papules are usually pea-sized, flattened, and of a dark red or violaceous color.
In some instances, not more than five or ten papules and pustules are present at one time; in others they may be numerous.
What modifications do the papules of the large-papular syphiloderm sometimes undergo?
The papules become somewhat flattened and are covered with dry, grayish or dirty-gray, somewhat adherent scales.
The lesions are but slightly elevated, and seem to partake of the nature of both macules and papules.
The papules are elevated and pointed, with a small zone of bright redness of the skin round the base of each.
