A 3 year old female spayed Boxer is presented to the veterinarian and you with an enlarged right popliteal lymph node. A FNA of the popliteal lymph node is examined cytologically and reveals a monomorphic population of large blastic lymphocytes. This enlarged lymph node is MOST LIKELY due to. (Choose ONE)
An 8 year old female spayed domestic shorthair cat has diarrhea, occasional vomiting, and weight loss. A biopsy of the cat's intestine reveals lymphocytes, which the pathologist cannot with certainty diagnose as cancer! The astute student veterinarian suggests the lymphocytes can be sent to a laboraotry for a clonality test (also known as a polymerase chain reaction for antigen receptor rearrangements [PARR] test) If the clonality test reveals only one band then the clinicians will diagnose (choose ONE)
A 6 year old female spayed Scottish terrier is presented to the veterinarian and you with hematuria (blood in her urine), pollakiuria (increased frequency of urination), and stranguria (straining to urinate). The dog is subsequently diagnosed with transitional cell carcinoma (TCC), which is a cancer of her lowr urinary tract. The owner notes that a group of closely related Scottish Terriers in different homes in differrent provinces is having more cancer than expected! You hypothesize the most likely mechanism for the increased incidence of cancer in this group of scottish terriers is (choose ONE)
A 1 year old intact male cat is presented for dyspnea (difficulty breathing) to the veterinarian and you. Together, using cytological examination of fluid from the cat's thorax, you diagnose a mss in the cat's chest as lymphosarcoma. Using an ELISA (enzyme linked immunosorbent assay) blood test, you also diagnose the cat is feline leukemia virus positive! You hypothesize the feline leukemia virus caused by lymphosarcoma by (choose the most likely mechanism)
