There is some exocytosis of inflammatory cells but not as prominent as in nummular dermatitis; Typical findings: [5] Psoriasiform hyperplasia, initially slight, with mild spongiosis; Usually numerous yeast-like organisms in the surface keratin

Maculopapular lesions exhibit superficial perivascular dermatitis with lymphocytic infiltrate and dilated vessels in the papillary and mid dermis with neutrophils, eosinophils, and nuclear debris. Epidermis revealed dispersed foci of hydropic changes, accompanied by minimum acanthosis , subcorneal pustules , slight spongiosis , Basal cell ...
