Apparent feline leukemia virus-induced chronic lymphocytic leukemia and response to treatment.
Chylothorax secondary to chronic lymphocytic leukemia (CLL) was diagnosed in a feline leukemia virus (FeLV)-positive 8-year-old castrated male domestic shorthair feline. The leukemia resolved following therapy with chlorambucil, prednisone, cyclophosphamide, doxorubicin, and lomustine. To our knowledge, this is the first reported case of CLL in an FeLV-positive cat. Although a causative relationship cannot be proven, patients diagnosed with either disease may benefit from diagnostics to rule out the presence of the other concurrent condition.
