    • Scaling is an accumulation of loose debris from the stratum corneum (corneocytes). Scaling can have various appearances and be dry, thin, slab or greasy and vary in color from white, silver, yellow, brown or grey.
    • Corneocytes are the end product of epidermal keratinization and the normal loss of these cells is not visible to the naked eye as corneocytes are released individually or in small groups. In abnormal scaling, there is a loss of large scales. Scaling may be primary in primary idiopathic seborrhea and ichthyosis. However, scaling is more often secondary to a chronic inflammatory process. In the presence of pruritus, the differential diagnosis should include parasitic infections, allergies, infectious diseases such as pyoderma or Malassezia dermatitis.
    • If pruritus is not present, differential diagnoses should include primary endocrinopathies, demodicosis, dermatophytosis, leishmaniasis, nutritional imbalances, metabolic diseases, and cutaneous neoplasia such as cutaneous epitheliotropic lymphoma. In cats, exfoliative dermatitis associated or not with thymoma should also be considered.

    • Exposure to ultraviolet light aggravates and exacerbates LED and there are breeds that may be predisposed since they are reported more frequently, as the Collie, Shetland Sheep Dog, Australian Shepherd, German Shepherd and Siberian Husky.
    • Therapeutic approaches are multiple and different effectiveness has been reported.
