Ocular lymphoma: A case study:
By Dr. Jamie N. Henningson, DVM, PhD, DACVP
A globe from a 12-year-old Chihauhau with a three-week history of a cloudy eye and corneal ulcer was submitted to the KSVDL. On examination of the globe, the ciliary body and adjacent choroid were expanded by sheets of monomorphic round cells (Figure 1) consistent with neoplastic lymphocytes. Immunohistochemistry was performed for B and T cell markers and the neoplastic cells were positive for B cell lymphoma (Figure 2). This animal had no enlarged lymph nodes or signs of illness. Primary ocular lymphoma in dogs is rare and is primarily part of multicentric lymphoma. In cats, lymphoma is the second most common intraocular neoplasm and is usually part of the systemic disease process. However, ocular disease is often the presenting complaint and may precede signs of systemic involvement.
Figure 1. Eye, Lymphoma. Ciliary body and choroid expanded by monomorphic round cells that are consistent with neoplastic lymphocytes.
Not only is neoplasia a common disease that affects eyes but so are other disease processes, such as autoimmune, trauma, and infectious causes. An autoimmune disease example is uveodermatolotical syndrome (Vogt-KoyanagiHarada syndrome (VKH)) in dogs, which is most often bilateral; diagnosis in one eye may help save the other eye if treatment is initiated immediately. Ocular biopsy submission can be an important diagnostic tool for your patient and client. To submit eyes for biopsy they should be left intact and not incised. Surrounding soft tissue can be trimmed if it does not appear to be involved in the disease. If there is a lesion present in the soft tissues surrounding the eye, leave the soft tissues intact. Place they eye in 10% neutral buffered Figure 2. Positive IHC staining for CD79a, a marker formalin immediately after enucleation. The eye should for B cells, confirming B cell lymphoma. be fixed in a ratio of 10X formalin volume: 1 X specimen volume. The formalin: specimen sample should be placed in a liquid tight container, and then placed into another container such as Ziploc baggie or whirlpack to prevent leakage during shipping. Including a clinical history explaining the course of disease and the lesions observed on ocular examination are important when submitting samples. Drawings of the lesion(s) location and/or clinical pictures are beneficial and appreciated. If you have questions about submitting eyes, please don’t hesitate to call Dr. Henningson at 785-532-1429 or email at heningsn@vet.k-state.edu.

Sample Submission for Bovine Abortions
By Dr. Gordon Andrews
We frequently receive phone calls this time of year for advice regarding what samples to submit for bovine abortions, so we are presenting this information as a reminder of the appropriate samples to collect for a thorough diagnostic workup. Abomasal fluid: Place in a sterile tube and label. This sample is for the bacteriology abortion panel which includes aerobic culture, Brucella and Campylobacter. Thoracic or pericardial fluid: Place in a sterile tube and label. This sample can be used for fetal serology for BVDV, Leptospirosis, Neospora, Bluetongue, and others. Fetal serology is a valid test to run only during the third trimester of pregnancy when the fetus is becoming immune competent. Formalin fixed tissues: Place in leak proof formalin container.
These tissues are examined microscopically for lesions indicative of an infectious cause of abortion. Brain (sections of cerebrum, cerebellum, midbrain and brainstem), heart, lung, spleen, liver, kidney, adrenal glands, thyroid gland, thymus, and skeletal muscle (3 sections from different muscle groups). Fresh tissues: Place pooled tissues in a whirlpack bag. Fresh tissues can be used for PCR testing for specific infectious agents (Leptospira, BVDV), bacterial culture, or virus isolation. Lung, liver, kidney, lymph node, spleen, heart, and thymus. Eye or ocular fluid: Place eye in whirpac bag, or fluid in sterile tube and label. This sample can be used for nitrate analysis if desired. Placenta: 3-4 sections of fresh cotyledons in a separate
whirlpac bag, and 3-4 sections of cotyledons in the formalin container. The fixed tissue is examined microscopically for evidence of placentitis. The fresh tissue can be cultured or other procedures such as bacterial culture, PCR, or virus isolation can be performed if there is microscopic evidence of placentitis. Fresh liver: Place one large sample in a separate whirlpac bag. This sample can be used for trace mineral and vitamin A analysis if nutritional deficiency is suspected as a cause of abortion or weak born calves. This information as well as many other case specific diagnostic workups is available on the KSVDL website at: http://www.ksvdl.org/ resources/case-specific-workups/

KSVDL Client Care: We are a great source of information!! The KSVDL Client Care group serves as an integral part of our team by facilitating communication for those of you out in the field and those of us in the laboratory. All incoming requests are handled by these folks who put every effort forward to ensure timely and accurate results are possible at the completion of each accession. Even before you package and ship your samples they are here
to answer any questions you may have about anything from submission forms to prepaid UPS shipping labels to what the cost and expected turn-a-round time is for the testing you need. They can also put you in contact with a diagnostician to assist you with more detailed questions or guidance. You may also find them reaching out to you for follow up on accessions that have reached
New Tests
the laboratory. This frequently occurs when one or two bits of information from you might assist those in the lab with proper testing or prompt resulting methods. Some specialized testing requires more detailed information that others. Client Care is also here any followup questions you may have with anything from resulting methods to result interpretation.
