Epidermal growth or differentiation disorders
Seborrheic disease complex
- Abnormal cornification or function of sebaceous glands
- Large amounts of free fatty acids and cholesterol
- Decreased amounts of diester waxes in surface lipids
- Bacterial population changes to pathogenic coagulase positive staphylococci
- Chronic disease affecting mainly dogs, sometimes cats and horses
- Dry form - white to grey scales
- Greasy form - scaly, excess brown to yellow lipids sticking to skin and hair
Primary idiopathic seborrhea
- Abnormal cornification
- Epidermal turnover reduced to about 2/3 of normal
- Microscopically:
- Hyperkeratosis distending follicular ostia causing papillary appearance
- Parakeratosis at edges of follicular ostia
- Congested, oedematous dermal papillae
- Spongiotic epidermis with leukocytes
