Derm - Inflammation (Final) Flashcards
What type of infection is Impetigo?
Describe the appearance
- Superficial pustular dermatitis
- nonfollicular pustules which develop into crusts
What is Intertrigo?
Describe the pathogenesis
- skin fold pyoderma
- path: closely apposed skin surfaces > frictional trauma > moisture > opportunistic bacterial infections
What is pyotraumatic dermatitis?
Describe the pathogenesis
Describe the gross appearance
- hot spots
- path: self trauma > bacterial infection
- underlying pruritis
- gross: moist, alopecic, raised, well-circumscribed lesions > ulceration/crusting
What type of infection is Greasy pig disease?
Describe the gross appearance
- exudative epidermitis
- Staph. hyicus
- gross: erythema > pustules > crusts
Describe the gross appearance of Dermatophilosis
- lesions on back or distal extremities
- pustules > exudate > matting of hair/wool > alopecia
- “lumpy wool”
Canine superficial spreading pyoderma
- gross appearance
- scaling, erythmatous macule (circular/ring shaped), papules, pustules, crusts, epidermal collarettes, alopecia
- folliculitis
Describe Demodicosis
- caused by Demodex
- grossly the same as canine sup. spreading pyoderma
- folliculitis, erythematous macules, alopecia and scaling
- localized: face and forelegs
Describe Dermatophytosis
- caused by fungi, colonizes keratin
- contagious
- self-limiting
- same as canine spreading pyoderma
- folliculitis, erythematous macules, alopecia and scaling
Pemphigu foliaceous
- what type of infection-
- gross appearance
- auto-immune disease involving hypersensitivity against cell adhesion proteins
- vesicles, pustules, crust, ulcers
- face, ears, footpads, clawbeds
What is the sequence of lesions for Poxviruses?
macule > papule > vesicle > umbilicated pustule > crust > scar
