Four professionals from the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) recently contributed to literature covering a novel case in a white-tailed deer. Three members of TVMDL’s anatomic pathology section, Josué Díaz-Delgado, DVM, MS, PhD, DACVP, Alexis Templeton, and Gabriel Gomez, DVM, PhD, DACVP, and Molecular Diagnostics Section Head Pam Ferro, PhD, were part of the team who worked on the case and contributed to the article. The article, published in the Journal of Comparative Pathology, covers the clinical, pathological, and immunohistochemical features of a presumptive primary cerebral T-cell (PCTCL) in a white-tailed deer. The deer was noted as having chronic progressive neurological disease characterized by ataxia, claudication, and eventual circling. The case concludes that PCTCL should be considered in the differential diagnosis of neurological disease and intracranial, intra-ataxia CNS masses in deer.
