Around the main focus of visible microvesicles, small pustules, seropapuly.Allergic rash (allergid) can occur far from the main chamber.
A variety of microbial eczemais the so-called coin-(nummulyarnaya), or blyashechnaya, eczema. It is characterized by the formation of sharply delineated lesions rounded shapes magnitude 1.3 cmTheir swelling and hyperemic surface states excessive wet, layering serous-purulent crusts. Most nummulyarnaya eczema localized to the upper extremities, but in some cases, the process can take common.Improper treatment of microbial eczema or trauma it is accompanied by the emergence of secondary foci of allergic rash - or mikrobidov allergid.During the progressive course of the secondary rash merge disseminiruyutsya with the formation of a large number of weeping erosive areas. In such cases, a transformation of microbial eczema true.
