A 6.5-year-old, male, non-castrated pet rabbit was presented with generalized exfoliative dermatitis, depression and anorexia. Skin laboratory examinations were negative for ectoparasites, bacteria and fungi whereas thoracic radiography revealed a large mediastinal mass. Complete blood and biochemical examinations did not show anything abnormal. Thymoma was suspected and therapeutic options were discussed but the owner declined. Supportive and symptomatic therapy was of no avail and severe deterioration of systemic symptoms necessitated euthanasia. Necropsy revealed a whitish-gray mass on the anterior and lower part of the mediastinum and pale voluminous liver. Histopathology confirmed the presence of thymoma and the hypothesis of thymoma-associated exfoliative dermatitis along with hepatic cirrhosis.
