Extranodal B-cell lymphoma in the urinary bladder with cytological evidence of concurrent involvement of the gall bladder in a cat.
A 15-year-old domestic shorthair cat was presented with severe haematuria, stranguria, anorexia and lethargy of 10 days' duration. Physical examination revealed a large painful urinary bladder and pain in the cranial abdomen. Abdominal ultrasound revealed severe generalised mural thickening of both the gall bladder and the urinary bladder. Lymphoma was diagnosed on cytology of urine sediment and fine-needle aspirates of the gall bladder. Despite a transitory clinical improvement and partial remission following chemotherapy, the cat was euthanased six weeks after initial presentation due to recurrent clinical signs. Post-mortem examination confirmed a B-cell lymphoma in the urinary bladder. This report is the first description of gall bladder and bladder lymphoma in a cat.
