#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 preexisting 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. Its most common sites are the scalp and face, especially in young people and in those who are ill-nourished and strumous. #What course does pustular eczema pursue?# Usually chronic, continuing as the same type, or passing into eczema rubrum. #Describe the symptoms of squamous eczema.# Squamous eczema (_eczema squamosum_) may be defined as a clinical variety, the chief symptoms of which are a variable degree of scaliness, more or less thickening, infiltration, and redness, with commonly a tendency to cracking or fissuring of the skin, especially when the disease is seated about the joints. It is developed, as a rule, from the erythematous or papular type. Itching is slight or intense. The disease is not uncommon upon the scalp. #What is the course of squamous eczema?# Essentially chronic. [Illustration: Fig. 23.
