#Describe the symptoms of papular eczema.#
Papular eczema (_eczema papulosum_) is characterized by the appearance, usually in numbers, of discrete, aggregated or closely-crowded, reddish, pin-head-sized acuminated or rounded papules. Vesicles and vesico-papules are often intermingled. The itching is commonly intense, as often attested by the presence of scratch-marks and blood crusts.

It is seen most frequently upon the extremities, especially the flexor surfaces.
#What course does papular eczema pursue?#
The lesions tend, sooner or later, to disappear, but are usually replaced by others, the disease thus persisting for weeks or months; in places where closely crowded, a solid, thickened, scaly sheet of eruption may result--eczema squamosum.
#Describe the symptoms of vesicular eczema.#
Vesicular eczema (_Eczema vesiculosum_) usually appears, on one or several regions, as more or less diffused inflammatory reddened patches, upon which rapidly develop numerous closely-crowded pin-point to pin-head-sized vesicles, which tend to become confluent and form a solid sheet of eruption. The vesicles soon mature and rupture, the discharge drying to yellowish, honeycomb-like crusts. The oozing is usually more or less continuous, or the disease may decline, the crusts be cast off, to be quickly followed by a new crop of vesicles. In those cases in which the process is markedly acute, considerable swelling and [oe]dema are present. Scattered papules, vesico-papules and pustules may usually be seen upon the involved area or about the border.
The face in infants (_crusta lactea_, or _milk crust_, of older writers), the neck, flexor surfaces and the fingers are its favorite localities.
#What course does vesicular eczema pursue?#
Usually chronic, with acute exacerbations. Not infrequently it passes into eczema rubrum.
#Describe the symptoms of pustular eczema.#
Pustular eczema (_eczema pustulosum_, _eczema impetiginosum_) is probably the least common of all the varieties. It is similar, although usually less actively inflammatory, in its symptoms to eczema vesiculosum, the lesions being pustular from the start or developing from preëxisting vesicles; not infrequently the eruption is mixed, the pustules predominating. There is a marked tendency to rupturing of the lesions, the discharge drying to thick, yellowish, brownish or greenish crusts.
