different types of eczema have their own distin-guishing marks, and these will
be dealt with later; most share certain general features, which it is
con-venient to consider here. The absence of a sharp mar-gin is a particularly
important feature that separates eczema from most papulosquamous eruptions.
eczema (Figs 7.3 and 7.4) is recognized by its:
weeping and crusting;
blisteringausually with vesicles
but, in fierce cases, with large blisters;
• redness, papules and swellingausually with an ill-defined border; and scaling.
eczema may show all of the above changes but in general is:
less vesicular and exudative;
more scaly, pigmented and thickened;
more likely to show lichenification
(Fig. 7.5)aa dry leathery thickened state, with increased skin markings,
secondary to repeated scratching or rubbing; and
more likely to fissure
is like jazz; it is hard to defineabut itshould be easy to recognize if you
bear in mind the physical signs listed above.
If it does not itch, it is probably not eczema.
