Instructions to Contributors

The Diagnostic Exercises (DEs) are an initiative of the Latin Comparative Pathology Group (LCPG), the Latin American subdivision of The Davis-Thompson Foundation (DTF). These exercises are contributed by members and non-members of the LCPG or DTF, from any country. Cases do not have to be something unusual, and all sub-specialties of pathology are welcome! Previous cases are available online at the Davis Thompson Foundation website and in the member’s section of the AAVLD website. Selected cases are also published in each number of the Brazilian Journal of Veterinary Pathology; if a case is selected for the latter, the authors will be contacted to request authorization before the DE is transferred to the B J Vet Path.
