Abstract

Background

Case reports are part of the evidence hierarchy in evidence-based practice and guide an important part of dermatologic practice.

Objective

This article discusses the role of case reports and series in evidence-based practice and suggests how to improve reporting.

Methods

This article was inspired by a forum on the role of case reporting in dermatologic practice presented at a meeting of the American Academy of Dermatology. It is based on an informal literature review and the authors' experience in systematically reviewing case reports in medicine and dermatology.

Results

Case reports significantly influence medicine. Often they are the first line of evidence for new therapies but rarely are sufficient to establish treatment efficacy. Frequently they are the first and sometimes major source for detecting rare adverse events. Guidelines for improving the reporting of case reports and series are discussed.

Limitations

This paper represents the views of the authors and is neither a systematic review of the literature nor a formal consensus document.

Conclusion

Case reports are an important part of medical literature and need to be taken seriously.
