A 15-year-old, castrated male, Domestic Shorthair cat presented with a 1-month history of non-pruritic hair loss. The majority of the hair loss was on the ventrum and was accompanied by fine scales and crusts. The skin beneath appeared shiny. The lesions progressively worsened despite treatment with prednisolone and Convenia. By time of presentation, the cat had become lethargic with a poor appetite and weight loss. A complete blood count, chemistry, and T4 measurement were within normal limits. Punch biopsies from the right medial forelimb, stifle, and elbow were submitted for histological evaluation.
