EVBM-Dermatology approach

What primary lesion is this?

Hive (Wheal): Fluid in the dermis

What primary lesion is this?

Nodule (inflamation, hyperplasia, neoplasia, deposits)

What primary or secondary lesion is this?

Alopecia (Hair shaft loss, Less hair production, synchronized shedding, follicular destruction, congenital)

(T or F) Hypotrichosis/alopecia can be nromal in some breeds since is genetic

TRUE

What primary or secondary lesion is this?

Follicullar cast (accumulation of keratin, that adheres to hair shaft extending above folicule.

What primary or secondary lesion is this?

Crust: (accumulation of exhudate in skin surface)

tufted crust

hair is trapped in the crust

thick + adherent crust

Hyperkeratosis/cronic disease

yellow/friable crust

serum-rich exhudate

scale crust

crust mixed mith scales (parece sarna)

What primary or secondary lesion is this?

Scales (como caspa)

• Chronic inflammation/allergies

• Endocrine disease

• Nutritional/metabolic disease

• low humidity

Secondary differentials for scales

• Idiopathic seborrea

• mutation

• Zinc-responsive dermatitis

• Nasal parakeratosis

Primary differentials for scales

What primary or secondary lesion is this?

comedones (como espinillas): accumulation of stratum corneum + sebum

leukotrichia

white hair

What secondary lesion is this?

Epidermal Collarette (often seen with papules or pustules, seen w/ superficial pyoderma.

What secondary lesion is this?

Lichenification (collagen deposition cause elephant skin, frequently accompanied by hyperpigmentation & alopecia)

Erosion or ulcer caused by self-trauma

Excoriation: will be linear since is caused by scratching area

What secondary lesion is this?

Fissure (vertical line that goes through epidermis/epidermis-dermis)

What secondary lesion is this?

Scar

Itch is the sensation. Pruritic behavior is the clinical sign

aja

What primary lesion is this? (area is pinched/pressed and blaches)

Erythema

What primary lesion is this? (<1 cm)

macule

What primary lesion is this? (>1 cm)

Patch

What primary lesion is this? (<1 cm)

Papule

What primary lesion is this? (>1 cm)

Plaque

What primary lesion is this?

Pustule

What primary lesion is this? (>1 cm)

Bulla

What primary lesion is this? ( < 1cm) serous fluid

Vesicle

Muscle that erects hair

Pili Arrector m.

In what surface of the pinna

Convex surface (Outer)
