This 8-year-old neutered male domestic shorthaired cat has a two-month history of pruritic generalized crusting dermatitis that has been poorly responsive to antibiotics and bathing (Figure 1). Six weeks ago, a mediastinal thymoma was surgically removed; the crusting dermatitis preceded the surgery and persisted unchanged postoperatively.
