For many students, interns/residents, and new veterinarians, the case report is their first publication submitted to a journal. It is recognized as an important educational tool in developing good clinicians as they detect novelty and generate hypotheses. The case report presents unusual, uncontrolled observations about clinical findings, the natural history of an illness, or the complications of treatments or interventions. It provides crucial and detailed information about an individual animal, which is often lost in research studies where individual results are aggregated. However, the "instructions to authors" pages provide limited and varied information for preparing a case report. There is a need for consensus and consistent guidance for the case report's authors. Shockingly, a 2014 survey of the awareness, knowledge, policies, and views of veterinary journal Editors-in-Chief on reporting guidelines for publication of articles revealed that only 50% of the editors knew what a reporting guideline was, and 35% said their journal referred to reporting guidelines in its instructions to authors. This master class examines the case report's merits and limitations, such as the inability to generalize, the unlikely possibility of establishing a cause-effect relationship, the danger of over-interpretation, and retrospective design. When written without guidance from reporting standards, case reports are generally insufficient and rejected. Using the CARE (CAse REport) guidelines will show participants how their implementation significantly increases the case report's rigorousness to guide clinical practice, inform clinical study design and be accepted for publication.
