| Question | Answer |
|---|---|
| pruritus | itchy skin |
| erythema | reddening of skin |
| alopecia | hair loss |
| crusting | scabs |
| collarette lesion | 'bullseye' lesion indicating infection |
| papule | red spot on skin |
| pustule | red spot on skin filled with pus |
| pyoderma | infection of skin |
| dermatitis | inflammation of skin |
| hyperpigmentation | darkening of skin indicating chronic inflammation |
| lichenification | thickened skin indicating chronic inflammation |
| wheals | hives |
| intertrigo | infection/inflammation in skin folds |
| pododermatitis | inflammation/infection of skin between toes |
| Flea Allergy Dermatitis (FAD) | allergic reaction to bites of fleas; infestation not necessary, can be a few bites |
| FAD SYMPTOMS | pruritus, crusts, erythemic skin, hair loss, not on flea prevention; 'pants' area affected |
| FAD PE FINDINGS | hair loss over hips/tail base/medial thighs/flanks, fleas/flea dirt in coat, tapeworm segments at rectum |
| FAD TREATMENT | flea prevention/control, need prevention for at least a few weeks, treat all animals in the household, treat underlying infection, control pruritus (steroids, Apoquel, OTC antihistamines) |
| Atopy/Atopic Dermatitis (AD) | allergic skin disease, inherited predisposition, signs appear between 1 and 3 years of age, can be food or environmental allergies |
| AD SYMPTOMS | pruritus, licking, alopecia, erythema, papules, crusting; often face, ears, feet, axilla, groin, flanks |
| feline AD SYMPTOMS | crusting lesions between eyes/ears or periorbital skin; called MILIARY DERMATITIS |
| AD DIAGNOSIS | usually by exclusion, RULE OUT underlying FAD or secondary infection, allergy testing, location of lesions, seasonality |
| AD TREATMENT | control pruritus, treat infection, reduce exposure to allergens, immunotherapy (cytopoint, allergy drops, infections), oral supplements |
| Otitis Externa (OE) | inflammation or infection in ears; bacterial, fungal (yeast), allergic, or parasitic (Otodectes ear mites) |
| OE SYMPTOMS | scratching/rubbing ears, shaking head, odor and/or discharge from ears, head tilt, painful when ears/head handled, seasonal component, swimming |
| OE PE FINDINGS | erythema, crusting, swelling of canals, discharge or debris on swab from canal |
| OE DIAGNOSIS | otic examination, ear cytology |
| OE TREATMENT | treat underlying cause (topical medication), frequent ear flushing, underlying allergic disease (food/environment) |
| Aural Hematoma | swelling of pinna; traumatic rupturing of blood vessel inside pinna, usually underlying infection/allergy |
| Aural Hematoma SYMPTOMS | swollen ear, painful ear, shaking head, scratching at ear |
| Aural Hematoma PE FINDINGS | soft, fluctuant swelling of pinna, may be complete or partial, erythema or debris in ear |
| Aural Hematoma TREATMENT | surgical (drain, cannula, incisional), or medical (treat underlying infection with oral or otic antibiotics/antifungals, control inflammation) |
| Aural Hematoma PREVENTION | treat at first sign of infection, don't let your dog hang it's head out the window |
| Pyotraumatic Dermatitis | 'HOT SPOT'; area of moist, crusting dermatitis caused by a break in the skin in which opportunistic bacteria can cause infection |
| Pyotraumatic Dermatitis SYMPTOMS/PE FINDINGS | most frequently in large breed/long coated dogs (GOLDEN RETRIEVERS); pruritic/crusty patch on skin, face/below or around ears other skin folds, warmer seasons, possible history of allergies, fleas/flea dirt |
| Pyotraumatic Dermatitis TREATMENT | clip/clean/scrub area, topical sprays, oral antibiotics, oral/injectable medication to control pruritus (steroids, Apoquel) |
| Pyotraumatic Dermatitis PREVENTION | dry dogs completely after bathing/swimming, treat underlying atopy, trim hair short, flea preventatives |
| Impetigo | 'puppy pyoderma'; dermatitis of young puppies (<4 mos of age) |
| Impetigo SYMPTOMS/PE FINDINGS | varying degrees of pruritus, papules/collarettes/erythema usually on groin, medial thighs, belly |
| Impetigo TREATMENT | usually self-limiting, topical cleansers, oral antibiotics if severe |
| Impetigo PREVENTION | regular cleansing, drying puppy thoroughly after bathing/swimming |
| Pyschogenic Overgrooming | hair loss caused by overgrooming; usually due to underlying stress/anxiety, usually exclusively in CATS |
| Psychogenic Overgrooming SYMPTOMS/PE FINDINGS | hair loss around groin/belly/lateral limbs, vomiting hairballs, may be skin lesions (crusts, erythema), may be accompanied by inappropriate urinations |
| Psychogenic Overgrooming DIAGNOSIS | by EXCLUSION, treat for FAD and ATOPY first then think psychogenic overgrooming |
| Psychogenic Overgrooming TREATMENT | treat any underlying issues first, control fleas, oral/injectable antibiotics; oral/injectable steroids WITH CAUTION, stress/anxiety management |
| Acral Lick Granuloma/Dermatitis | lesions usually located @ the distal part of one of the limbs, caused or worsened by obsessive licking |
| ALG/D SYMPTOMS/PE FINDINGS | area of swollen, moist, crusting dermatitis on distal limbs (carpus, dorsal paw, tarsus), area may become lichenified/alopecic, history of atopy/anxiety |
| ALG/D TREATMENT | very difficult to resolve 100%, control secondary infection, control pruritus, control anxiety, prevent licking, can try surgical removal but pt may begin licking elsewhere, intralesional injection of steroids/acupuncture/laser therapy |
