My cairn terrier, 12 years old, had a physical a month ago. His senior profile came back with elevated lymphocyte count - first time observation. My vet suspected lymphoma although no enlarged lymph nodes. We did an ultrasoud - normal. We did x-ray - nothing obvious. We repeated CBC/differential and the lymphocyte count was higher than 3 weeks earlier. The vet said we could do a bone marrow aspirate to test for leukemia. But first we decided to do a tick serology to rule out chronic infection. That came back negative with lyme borderline. We are now going to treat with deoxycycline for 21 days and repeat CBC/differential. He also has had consistently high alkaline phosphatase levels but all tests [dexamethasone, ACTH etc. were normal]. The vet also feels that he is pre-Cushings. He looks and acts fine. Any thoughts on what is going on?
How high is the Lymphocyte count?? Slight elevations sometimes does not mean anything. If they continue to rise then a lymph node biopsy and a bone marrow biopsy would be indicated. This may help with a diagnosis. It sounds like your vet is on the right track. vetcare
