This document provides guidance on how to write a case report. It outlines the typical sections included in a case report, which are: title, key words, abstract, introduction, case presentation/report, discussion, conclusion, informed consent, and references. The introduction provides background on the case and why it is important. The case presentation provides detailed information about the patient's history, examination, diagnosis, treatment and follow-up. The discussion analyzes the case and links it to current literature, and the conclusion states the lessons learned from the case. The document emphasizes that a case report, while not the highest level of evidence, contributes to medical knowledge by reporting on new, rare or unusual cases.
