Case reports are valuable for documenting unique or rare clinical cases, providing detailed insights that contribute to medical knowledge and clinical practice. Unlike large-scale studies, which focus on broader patient populations, case reports emphasize an individual patient's presentation, diagnosis, treatment, and outcomes. This format allows clinicians and researchers to share novel observations, unexpected responses to treatment, or rare manifestations of disease, often serving as the first evidence of new medical conditions or unusual complications. Case reports are especially important in highlighting exceptions to general medical understanding, prompting further research, and guiding practitioners in similar rare cases by offering specific, real-world examples.

​

1. Select an Appropriate Case

• Choose a Unique or Rare Case: Look for cases with unique presentations, rare conditions, novel treatment outcomes, or unexpected complications.

• Assess Clinical Relevance: Consider whether this case will contribute new insights to the field, change clinical practice, or raise awareness of uncommon conditions or presentations.

• Confirm Patient Consent: Obtain written informed consent from the patient to share their medical information, ensuring they understand how their data will be used.

​

2. Conduct a Thorough Literature Review

• Research Existing Cases: Search databases like PubMed, Google Scholar, and relevant journals to identify similar cases, treatment approaches, and outcomes.

• Identify Knowledge Gaps: Note if there are aspects of your case that haven’t been reported previously, which will strengthen its contribution to the literature.

• Compile Key References: Save key articles and similar case reports that will be useful for comparisons and discussion.

​

3. Organize and Outline the Case Report Structure

• Abstract: Prepare a concise summary of the case, including the patient’s presentation, diagnosis, treatment, and outcome.

• Introduction: Provide context for the case and explain why it is noteworthy. Mention the relevant condition's prevalence, usual presentation, and clinical importance.

• Case Presentation: Describe the case in detail, covering all clinical information from history to outcomes.

• Discussion: Compare your case with existing literature, highlight unique aspects, discuss implications, and identify areas for further research.

• Conclusion: Summarize key takeaways, their significance, and recommendations.

• References: List all sources cited, formatted in your target journal’s required style.

​

4. Write the Abstract

• Summarize the Key Points: Focus on the case’s unique aspects, diagnosis, treatment, and outcome.

• Be Concise but Informative: Limit the abstract to 150-250 words, emphasizing why this case is significant.

• Use Keywords: Include essential keywords that enhance discoverability, like the condition, key symptoms, or treatments.

​

5. Introduction

• Define the Clinical Problem: Briefly outline the condition’s background, typical prevalence, and importance.

• Explain the Case’s Rarity or Novelty: Describe why this case stands out compared to typical presentations.

• Set Objectives: State the aim of the report—such as to raise awareness, document an unusual outcome, or suggest a hypothesis.

​

6. Case Presentation

• Patient History:

  • Presenting Complaint: Describe the patient’s main symptoms, onset, and duration.

  • Medical History: Note any relevant past medical conditions, medications, or family history.

  • Social and Lifestyle Factors: Include lifestyle factors (e.g., smoking, occupation) if relevant to the case.

• Examination Findings:

  • Physical Examination: Document key physical exam findings, mentioning normal and abnormal findings in clear, objective terms.

  • Diagnostic Tests: List all relevant diagnostic tests, including lab results, imaging, and other investigations. Use images if appropriate, with proper permissions.

• Differential Diagnosis:

  • List Potential Diagnoses: Briefly mention the different conditions considered during the diagnostic process.

  • Describe Diagnostic Reasoning: Explain how the final diagnosis was determined and ruled out other conditions.

• Treatment:

  • Interventions: Describe treatments given, including medications, dosages, procedures, and non-pharmacological measures.

  • Timeline: Use a timeline to show the treatment course, any adjustments, and outcomes. Ensure it’s detailed but easy to follow.

• Outcome and Follow-Up:

  • Describe Patient’s Response: Detail the patient’s response to treatment, including recovery, complications, or relapses.

  • Follow-Up Visits: Mention any relevant follow-up appointments, additional treatments, and long-term prognosis.

​

7. Discussion

• Compare with Existing Literature:

  • Highlight Similarities and Differences: Compare your case’s presentation, treatment, and outcome with similar cases in the literature.

  • Discuss Unusual Aspects: Emphasize aspects that are novel or unique in your case, exploring possible reasons for these differences.

• Explain Clinical Implications:

  • Broader Relevance: Explain the broader clinical relevance—such as how this case might influence diagnosis, treatment, or understanding of the condition.

  • Lessons Learned: Identify any lessons that could apply to other similar cases or improve clinical practice.

• Limitations:

  • Acknowledge Limitations: Briefly mention any limitations of your case, such as lack of long-term follow-up or limited generalizability.

​

8. Conclusion

• Summarize Key Points: Offer a concise summary of the case’s main findings and their significance.

• Clinical Takeaways: List practical takeaways or recommendations for other clinicians.

• Future Research: Mention if your case suggests areas for further research, such as studies to confirm findings or test related hypotheses.

​

9. Prepare Figures, Images, and Tables

• Incorporate Visuals: Use relevant figures (like imaging studies or lab results) to support findings. Make sure they’re clear and add value to the text.

• Provide Descriptive Legends: Add clear, informative captions for each figure or table, describing what is shown and its significance.

• Ensure Patient Anonymity: Remove any identifiable information to protect patient privacy.

​

10. References and Formatting

• Use Appropriate Citation Style: Follow the referencing style required by your target journal, such as APA, AMA, or Vancouver.

• Include Key Literature: Make sure to reference all relevant studies, reviews, or guidelines that support your case.

• Proofread Citations: Double-check all citations for accuracy and completeness.

​

11. Review and Edit the Case Report

• Check for Accuracy: Verify all medical information, including diagnosis, treatment details, and lab values.

• Ensure Clarity and Flow: Make sure the writing is clear, logically organized, and free from unnecessary jargon.

• Proofread for Grammar and Style: Review for grammar, spelling, and style consistency.

• Seek Peer Feedback: If possible, have colleagues or mentors review the case report for suggestions.

​

12. Submit for Publication

• Choose the Right Journal: Select a journal that publishes case reports in your field. Ensure your case aligns with its scope and audience.

• Follow Submission Guidelines: Format the report according to the journal’s submission guidelines, including word limits, structure, and image requirements.
