Lymphoma: perhaps one of the most common systemic neoplasms you will see in practice. The presenting complaint(s) will vary and range from anorexia, vomiting, diarrhea, coughing, uveitis, or the ever common “enlarged glands.” In fact, the majority of all lymphoma patients present with ONLY lymphadenomegaly, while still happy, eating, and wagging their tail.
While being asymptomatic is a good prognostic indicator (these animals are defined as “substage a”), sometimes it precludes an early diagnosis as owners cannot possibly believe their happy and seemingly healthy dog has cancer. And while everyone loves a good differential list, which may include rickettsial, fungal, or allergic disease, a patient with moderate to severe lymphadenopathy has lymphoma until proven otherwise. While running tick titers or fungal antigen tests are not wrong, that patient should not leave the clinic that day without a fine needle aspirate and cytology of a lymph node. This will get you your answer 90% of the time. IF you run into the 10% of cases for which cytology is inconclusive, there are plenty of other options at your disposal. In addition, these options also provide immunophenotyping (B vs. T cell), which remains one of the most important prognostic factors for canine lymphoma.

“Marcus” is a 5.5 yr CM Mixed Breed dog that was presented to his primary veterinarian for a 2 day history of lethargy and anorexia after known dietary indiscretion. Initial diagnostics included comprehensive bloodwork, radiographs and abdominal ultrasound. Baseline bloodwork revealed markedly elevated amylase and lipase and elevated liver values (ALP 228 U/dL, Total Bilirubin 2.4 mg/dL) and a neutrophilic leukocytosis (20,000 WBC/uL). Abdominal radiographs revealed decreased serosal detail and moderate gas distension of the stomach and small intestinal loops. Preliminary abdominal ultrasound confirmed peritoneal effusion and demonstrated a potentially edematous pancreas. Marcus was treated for a presumptive diagnosis of pancreatitis with IV fluids, antibiotics, antiemetics, and a lidocaine CRI for analgesia. He was referred to Charleston Veterinary Referral Center for continued in-patient care. Read More >
Zoe is an 8 year old SF Italian Greyhound that was presented with acute collapse. She was last normal that morning, when on a walk during the day she became ataxic, vomited and needed to be carried back to the house. She was presented to her primary veterinarian where she was assessed as having dull mentation. She was non ambulatory, hypothermic, dehydrated and icteric. Her veterinarian administered 200 ml (40 ml/kg) warm LRS subcutaneously and immediately referred her. Read More >
Folly presented to the CVRC Neurology/Neurosurgery Service for evaluation of cervical pain. Folly had originally presented to Park West Veterinary Associates’ Dr. Goldsmith for cervical pain two weeks prior to referral. Dr. Goldsmith had taken cervical radiographs and was suspicious of an intervertebral disc extrusion. He had then prescribed strict kennel confinement and rest with Tramadol and Methocarbamol for analgesia and sedation. In spite of the excellent care the owner had taken with her, and Dr. Goldsmith’s exceptional medical treatment and advice, Folly continued to be apparently painful so she was sent to CVRC.

History: Phoebe, a 14 year old female spayed English Springer Spaniel (18kg), was referred to the Cardiology Service for coughing, tachypnea, abdominal distention, and extreme lethargy with any exercise. Phoebe’s owner first noticed a dry hacking cough about 1 year ago. In the month prior to presentation, Phoebe’s coughing spells had worsened, and were occurring multiple times throughout the day and night (recently her cough was so bad that she had been keeping her owner awake during the night). For the last couple of days prior to presentation, flecks of blood were found in the mucus she expectorated. Her owner was particularly concerned about her energy level. Phoebe had always enjoyed going on walks and playing with other dogs at the dog park, but recently she was tiring more easily (activity level is 50-70% of normal). Her abdomen also became distended in the 24 hours prior to presentation. Read More >
Koda is a 4 yr old intact male Dachshund that was presented to his primary veterinarian for vomiting of 12 hours duration after ingesting a pork bone for dinner. While being examined at the primary veterinary hospital, Koda had an episode of hematamesis but was quiet, alert and responsive. Abdominal radiographs were suspicious for a mineral density intestinal foreign body obstruction and Koda was referred for continued care. On initial presentation, Koda was stuperous. His temperature was 103.5 F, heart rate was 220 bpm and his respiratory rate was 36/minute. His membranes were dark red, tacky and his CRT was 3 seconds. He had no palpable metatarsal pulses and his limbs were cold. His abdomen was splinted and he had repeated bouts of hematochezia. Read More >

It is the most commonly diagnosed neuromuscular disease in companion animals and is quite common in people as well. Read More >
