Dogs, lymphoma and ICC

SUNAO FUJITAImmunocytochemistry (ICC) is an adjunct diagnostic tool, which helps to identify cellular origin utilizing the accuracy of antibody-antigen binding. In comparison with immunohistochemistry (IHC), which is more commonly used in both human and veterinary medicine, ICC is not routinely exploited for the classification of a variety of neoplastic lesions.However, ICC has the potential to […]

Case of the month

KATHRYN JENKINSFine needle aspiration (FNA) can quickly and easily identify whether an enlarged lymph node is hyperplastic/reactive, inflamed, or neoplastic (e.g. lymphoma). It can also aid in the identification of potential metastatic disease (e.g. mast cell tumours, carcinoma, histiocytic sarcoma), and can also identify uncommon infectious agents.A recent case highlighted the usefulness of lymph node […]

Liver sampling

ROB FAIRLEYWhen sampling the liver for histology (especially for cases with known liver disease) it is helpful to take multiple pieces and it is really helpful to make sure that what you select includes some decent-sized bile ductules. Facial eczema, for example, preferentially affects the larger ductules.Some livers may have really badly affected areas (the […]

Brain histology

ROB FAIRLEYIf you require brain histology performed, you should ideally send  the whole brain, fixed in formalin, to the laboratory. If you need to take a fresh sample, you can remove a small portion no problem.We receive submissions every now and then that consist of cerebral cortex only. If you are specifically checking for polio […]

Case of the month

BERNIE VAATSTRAThis month we present two cases caused by the same aetiological agent.Case 1:Seven first-calving Friesian heifers from a Waikato dairy herd developed fever and respiratory distress and three died after returning from grazing and presumably being exposed to BHV-1 circulating in the home herd. Necropsy findings included severe necrotising tracheitis (Figure 1) and pneumonia. […]

Plasma ACTH testing reminder

We featured an article in June 2019 regarding factors that can interfere with ACTH testing for diagnosis of Pars Pituitary Intermedia Dysfunction (PPID) in horses. Since both non-PPID and PPID horses display higher ACTH concentrations in autumn (March, April, May) compared with other times of the year, now is a timely reminder of these interfering factors.>> […]
