The Case for Case Reports

The document emphasizes the critical role of case reports and case series in medical science, particularly in dermatology, despite their low position in the evidence hierarchy. Case reports have been instrumental in the discovery of significant drugs, such as propranolol for infantile hemangiomas and minoxidil for androgenetic alopecia, and in identifying rare adverse drug effects and new or rare diseases. They serve as early indicators of new epidemics and are practical for solo practitioners, who may not be able to conduct randomized controlled trials. However, they are limited by the absence of control groups, the possibility of non-representative cases, and a bias towards publishing successful or interesting outcomes. Nonetheless, the authors advocate for the continued importance of case reports and series in medical literature for their contributions to new findings and the promotion of further research.
