Some of the lesions are fluid-filled blisters and others have crusty scabs. Light microscopy is most likely to show which of the following findings?
A. Branching fungal hyphae without yeast forms
B. Diffuse separation of dermis and epidermis
C. Granular deposits of lgA at the tips of dermal papillae
D. lmmunofluorescent staining for C3 along the epidermal basement membrane
E. Multinucleated giant cells and neutrophil infiltrates
F. Nonbranching fungal hyphae with abundant yeast forms
