Scaly Red Rash 2: ?psoriasis Red or pink papule/plaque with silvery or micaceous scaling. The fingernails may show dystrophy, depressions known as "pits" and subungual debis presence of a thickened epidermis and stratum corneum containing neutrophils and neutophilic debris; no granular layer, elongation of the rete ridges; T cell involvement in etiology

Scaly Red Rash 4: ?eczema Eczema is very itchy. There are variants of eczema, the so-called "messy" rash, for example, "irritant" eczema, atopic eczema, and contact eczema, all of which are characterized by rashes that are quite itchy and appear "messy" because they are often scratched.TH2 mediated DTH Flexural distribution Lichenification from scratching crusting in the stratum corneum (making one think of a "messy rash") and the "spongiosis" or epidermal edema, as evidenced by the relative pallor around the keratinocytes.
