Clinical And Histological Recovery Of Non-Thymoma-Associated Exfoliative Dermatitis In A Cat Treated With Ciclosporin A

A 6-year-old neutered female European Shorthair cat with chronic, pruritic, alopecic, and exfoliative dermatosis unresponsive to various treatments was diagnosed with non-thymoma-associated exfoliative dermatitis. Despite normal blood tests and negative retrovirus tests, histological examination revealed significant skin abnormalities. Treatment with ciclosporin A (7 mg/kg) led to dramatic clinical improvement within 3 weeks, with subsequent histological resolution of skin issues. This case suggested an immune-mediated process and highlighted ciclosporin A as an effective treatment, marking the first report of such recovery in non-thymoma-associated exfoliative dermatitis.
