Branching fungal hyphae without yeast forms = probably Sporotrichosis / Sporothrix schenckii

Diffuse separation of dermis and epidermis = Stevens-johnson / TEN

Granular depositis of IgA at the tips of dermal papillae = dermatitis herpetiformis

Immunofluorescent staining for C3 along the epidermal basement membrane = bullous pemphigoid

Nonbranching fungal hyphae with abundant yeast forms = ? (maybe tinea?)
