Given the unpredictable and challenging nature of medicine, many medical students will have come across a patient who has not been a textbook case. The patient may have presented in an unusual way, had a strange new pathology, or reacted to a medical intervention in a manner that has not been seen before. The publication of these novelties and curiosities as case reports has for many centuries been a fundamental way of sharing knowledge and conveying medical experience, and throughout history there have been famous case studies that have helped shape the way we view health and disease (box 1).

Box 1: Famous case reports

Multiple myeloma Henry Bence-Jones (left) and William MacIntyre contributed greatly to our understanding of multiple myeloma by recording the effect of this disease on Thomas Alexander McBean. They found that Mr McBean’s urine was “abound in animal matter.” It is owing to this observation that the protein found in urine of patients with multiple myeloma is called Bence-Jones protein. 2 Mental health disorders Sigmund Freud, best known for his psychoanalysis and theories of the unconscious mind, also had a special interest in recording the case histories of his patients.

PreparationWhen you have found a suitable case it is vital to do a number of tasks before you can start putting pen to paper.

Literature reviewA literature review on a medical database such as PubMed, Ovid, or Medline can be used to check if there have been any similar cases; this helps you gauge how rare your case is.

Liaising with doctors in chargeIt is very important to discuss writing a case report with the senior clinician in charge of the patient’s care. Not only must you gain their permission, but they will also help to provide guidance and advice. In addition, it is also worth discussing the case with clinicians of other specialties (such as pathology, radiology, and microbiology) who have played a role in the patient’s care.

Gaining consentCheck the journal guidelines carefully. It is extremely important to gain written consent from the patient if you wish to include pictures or clinical details from which they may be identified. During the consent process you must explain why you wish to share their case with others, the risks and benefits of doing so, and you must answer any questions they may have. Get senior help for this.

Data collectionWhen you have done your literature review, liaised with the senior doctor, and gained consent from the patient you can start bringing your patient’s case together. This involves finding his or her medical notes, laboratory results, imaging, and any other relevant material.

How do I structure a medical case report?The basic structure of a medical case report is as follows:

Abstract• —This section is read by people trying to decide whether they wish to go on and read your full case report. It is therefore vital to keep it concise (no more than 150 words) and snappy, and to encompass all the important aspects of your case, particularly highlighting what this adds to medical knowledge.Case report—In this section you are presenting your patient to the •reader. This should include a concise history and any relevant examination and investigation findings. It is important to include any relevant negatives based upon the potential diagnoses, but do not clutter this section with unnecessary detail.Discussion—When you have presented your case to the reader •you are expected to put it into context in the discussion section. Here you give information about the condition or intervention in question, such as the basic epidemiology, pathophysiology, clinical presentation, investigations, and treatment. As you paint this picture it is extremely important for you to show how your case has differed from the norm and how this is contributing to medical understanding.

Where can I get my case reports published?Given the reluctance of many journals to publish case reports these days, where are you to turn when you wish to share your newly written up experience of an interesting case?

Fortunately, the vastness of cyberspace has allowed for the development of a new breed of medical journal. A number of new online journals such as BMJ Case Reports (www.casereports.bmj.com), Cases Journal (www.casesjournal.com), the Journal of Medical Case Reports (www.jmedicalcasereports.com), Radiology Case Reports (www.radiology.casereports.net/index.php/rcr), and the Journal of Dermatological Case Reports (www.jdcr.eu) allow the publication and dissemination of notable case reports. These

allow doctors from all over the world to share their experiences of new and interesting cases. Although still in their infancy, these journals have the potential to act as large case banks that allow doctors to search for cases similar to ones that may be puzzling them, to help guide their management.
