Reinero, Carol R.; Masseau, Isabelle; Grobman, Megan; Vientos-Plotts, Aida; Williams, Kurt

A 7-year-old FS DSH cat was presented for potential mammary tumors. The cat had lived in South Korea for 2.5 years until 9 months before presentation. The cat had been treated for psychogenic alopecia with megestrol and methylprednisolone acetate and subsequently developed mammary masses. Relevant history included exposure to "yellow dust" in South Korea, a serious environmental health threat affecting air quality and leading to respiratory disease in humans. in the right cranial lung lobe, which could not easily be ascribed to asthma, lobectomy was performed. Histology identified mild to moderate eosinophilic bronchitis and bronchiolitis with luminal mucus accumulation, moderate bronchial gland hyperplasia, mild subpleural air trapping consistent with asthma, but no evidence of an infiltrative disease was found ( Figure 12 ). The cat initially was treated with PO, followed by inhaled, corticosteroids and a weight loss plan with marked clinical improvement.
