1

acute dermatitis

Intra epidermal vesicles containing white cells and debris
spongiosis (intracellular oedema)

2

psoriasis

parakeratosis
epidermal hyperplasia
micro abscesses
elongates, fusion and clubbing of rete edges
blood vessels close to the surface

3

bullous pemphigoid

Fluid filled bulla with eosinophils, between epidermis and dermis
split through DEJ

4

toxic epidermal necrosis

intra epidermal split at DEJ

5

orthohyperkeratosis
formation of cytoid bodies
band like upper dermal infiltrate of lymphocytes

6

rosacea

patchy inflam with plasma cells
perifollicular granulomas

simplex - affects keratinocytes
junction - affects lamina lucida
dystrophic - affects lamina densa
