spongiotic dermatitis

A generic term for a broadly defined histopathologic pattern characterised by “eczema”, often associated with an increase in eosinophils occurring in a background of contact dermatitis, atopy and drug reactions.

inflammation of the skin. Dermatitis can result from various animal, vegetable and chemical substances, from heat or cold, from mechanical irritation, from certain forms of malnutrition, or from infectious disease.

actinobacillary dermatitis
rare disease in cattle; large ulcers discharging yellow pus or nodules, on lymphatics with local lymph node enlargement.
acute moist dermatitis
a superficial bacterial infection of the skin, usually caused by self-trauma, i.e. scratching, rubbing, biting. In dogs, ectoparasites, otitis, anal sacculitis and pruritic skin diseases are common precipitating causes. Affected skin is moist, weeping, and has a covering of matted haircoat and dried exudate. Staphylococcus spp. are usually present. Called also pyotraumatic dermatitis, 'hot spots'.

allergic inhalant dermatitis
see canine atopy.
atopic dermatitis

part of several infectious mucosal diseases of cattle; also in equine pemphigus.
dermatitis crustosa

equine exfoliative eosinophilic dermatitis
characterized by infiltration of eosinophils and granulomatous inflammation with ulcerative stomatitis and wasting; suspected of being a hypersensitivity to Strongylus equinus larvae.

feline miliary dermatitis
a papular, crusting skin disease located predominantly on the back, with varying degrees of pruritus. Ectoparasites, food and drug allergy, and infection by fungi or bacteria are among the many possible causes. Called also scabby cat disease.

fibrosing dermatitis
dermatitis sufficiently severe to affect deep layers of the dermis results in scarring of the skin due to excessive fibrous tissue formation.
filarial dermatitis
fold dermatitis
moisture, friction and secondary infection in body folds such as facial fold in brachycephalic dog breeds, tail fold in dog breeds with extremely short, often screw, tails, lip fold in spaniel breeds, perivulvar fold in obese bitches, and all over the body in the Shar pei.

a transient, superficial dermatitis, mostly about the head in horses; may be all over the body in pigs. Caused by pediculoides ventricosus or tyroglyphus.
granular dermatitis

dermatitis herpetiformis
chronic dermatitis in humans marked by successive crops of grouped, symmetrical, erythematous, papular, vesicular, eczematous or bullous lesions, accompanied by itching and burning; a granular deposition of IgA immunoglobulin around the lesion almost always occurs. Occurs rarely in dogs.

Malassezia dermatitis
a pruritic, seborrheic skin disease of dogs, particularly some breeds including West Highland white terriers, Shetland sheepdogs, Poodles, and Cocker spaniels, and rarely cats, caused by colonization of the skin by the yeast, Malassezia pachydermatis. There is usually an underlying cause such as atopy or bacterial pyoderma.
