Answer

Staphylococcus species and group A beta-hemolytic streptococci are the most frequent organisms cultured from skin lesions. Superinfected eczematoid lesions appear as erythema associated with serous or purulent exudates and crusting. Greasy moist scales on the surface of the lesions and small pustules at the advancing edges may be present. Always consider infection in acute flares of chronic atopic dermatitis or in cases that are unresponsive to appropriate therapy.
