* = '''Exudative epidermitis of pigs'''
*Caused by [[Staphylococcus spp.#Staphylococcus hyicus|''Staphylococcus hyicus'']]
*Affects neonatal piglets - often fatal, older piglets - milder disease
*Focal erosion of stratum corneum
*Brown exudate
*Dermatitis around eyes, ears, snout, chin and medial legs, may spread to ventral abdomen and thorax
*Rapidly becomes generalised -> greasy exudate over red skin -> hardened, cracked exudate
*In older piglets, milder localised disease develops around eyes, ears and face
*Grossly:
**Thickened epidermis, scaling
*Microscopically:
**Early - subcorneal pustular dermatitis extending to hair follicles -> superficial suppurative folliculitis
**Late - hyperplastic epidermis, thick keratin crusts with cocci, microabscesses
