DIFFERENTIAL DIAGNOSIS OF FELINE PRURITUS

摘要

Flea Allergy Dermatitis: Affects the dorsal lumbo-sacral region, caudo-medial thighs, ventral abdomen, and flanks. Food Allergy: Affects the pre-aural region, pinnae, neck, periorbital region, face; Non-seasonal pruritus Atopic Dermatitis ("Catopy "):May mimic the distribution patterns of Flea Allergy or Food Allergy, or may also present with lesions of the forelegs, rear legs, ventral abdomen and chest.Parasitic Causes: Presence of "miliary lesions" implies a hypersensitivity response; Cheyletiellosis ("Walking Dandruff)—affects primarily the dorsal trunk, excess scaling a major sign; Notoedric Mange (Feline Scabies)— affects the pinnae, face, periorbital region, neck ("Head Mange")—heavy crusts/scales. May extend to the feet, perineum; Trombiculosis ("Chiggers")—affects ground contact areas—legs, feet, ears, and ventrum with orange colored crusts.
