A case report is one of the most accessible ways for a medical student to get published, and the process is more straightforward than you might expect. The core structure follows a standardized checklist, the writing is concise (most case reports run 1,500 to 3,000 words), and you don’t need to design a study or recruit participants. What you do need is a compelling case, a solid literature review, a willing mentor, and the discipline to follow reporting guidelines precisely.
Finding a Case Worth Reporting
Not every interesting patient encounter is publishable. A case report needs to offer something genuinely new to the medical literature. That “something new” typically falls into one of several categories: a rare or previously undescribed clinical presentation, an unexpected outcome (good or bad), a novel treatment approach, a unique adverse drug reaction, or an unusual link between symptoms and a disease not previously associated with each other.
The quickest way to test whether your case qualifies is to search PubMed for similar reports. If dozens already exist describing the same scenario, your case likely won’t add much. If you find very few or none, you may have something worth writing up. A good rule of thumb: your case should either describe something that hasn’t been reported before, or it should challenge or refine what clinicians currently believe about a condition.
Start paying attention during clinical rotations. When an attending says “I’ve never seen this before” or a patient’s course takes a turn nobody predicted, that’s your signal to investigate further. Talk to residents and attendings about whether they’ve encountered cases they never wrote up. Many physicians are sitting on reportable cases but haven’t had the time to draft a manuscript. Offering to do the writing gives you a publication and gives them a co-author credit with minimal effort on their part.
Searching the Literature Effectively
Before you commit to writing, you need to confirm your case is truly novel. This means conducting a thorough PubMed search rather than a quick Google query. The most effective approach uses MeSH (Medical Subject Headings) terms, which are the standardized vocabulary PubMed uses to index articles. About 89% of your relevant search results will come from MeSH-based queries, so learning this system pays off immediately.
Start by entering your key clinical terms into the MeSH database to find the official headings. Each MeSH term has subheadings you can use to narrow your focus, such as “adverse effects,” “diagnosis,” or “therapy.” Combine terms using Boolean operators: AND to narrow results, OR to broaden them. Filter your results to human subjects by adding the MeSH term “Humans” connected with AND. If you don’t have library access to full-text articles, add the filter “loattrfree full text” to your search strategy to surface only open-access publications.
Document your search strategy as you go. Journals increasingly ask authors to describe how they confirmed a case’s novelty, and having your search terms and results recorded will save time later.
Following the CARE Guidelines
The CARE (CAse REport) checklist is the reporting standard most journals require for case reports. Think of it as your structural blueprint. The checklist walks through every element your manuscript needs, and following it closely increases your chances of acceptance. Here’s what each section requires:
- Introduction: A brief explanation of why this case is unique, with references to the existing medical literature. Two to three paragraphs is usually enough.
- Patient Information: De-identified demographics, the patient’s primary concerns and symptoms, medical and family history, psychosocial background, relevant genetic information, and any past treatments along with their outcomes.
- Clinical Findings: The significant results from the physical examination.
- Timeline: A chronological summary of the episode of care, often presented as a figure or table. This is one of the most useful elements for readers and reviewers, so invest time making it clear.
- Diagnostic Assessment: The methods used (labs, imaging, physical exam), any diagnostic challenges you encountered, the final diagnosis, and other diagnoses that were considered and ruled out.
- Treatment and Outcomes: What was done, what was expected to happen, and what actually happened, including any adverse or unanticipated events.
- Discussion: Strengths and limitations of the clinical approach, a review of relevant literature, and the rationale for your conclusions.
- Conclusion: One paragraph summarizing the main “take-away” lessons, written without references.
- Patient Perspective: A section where the patient shares their own experience with the treatment. This is often overlooked but is part of the CARE standard.
- Informed Consent: Confirmation that the patient provided consent for publication.
Writing the Case Presentation
The case presentation is the heart of your report, and it should read like a clear, chronological story. Present information in this order: patient description, clinical history, physical examination findings, results of diagnostic tests and investigations, the treatment plan, the expected outcome, and the actual outcome. Resist the urge to editorialize in this section. Save your interpretation for the discussion. Here, you’re just laying out what happened.
Write in past tense and keep sentences direct. Instead of “The patient was noted to have presented with complaints of chest pain radiating to the left arm,” write “The patient presented with chest pain radiating to the left arm.” Every sentence should move the clinical narrative forward. If a lab value or imaging finding didn’t influence the diagnosis or treatment, leave it out.
The timeline element deserves special attention. A well-designed timeline table or figure can communicate in seconds what takes paragraphs to describe in prose. Include dates (or intervals like “Day 1,” “Week 3”), key symptoms, diagnostic milestones, treatments initiated, and clinical responses. Reviewers consistently flag missing or unclear timelines as a reason for revision.
Writing a Strong Discussion
The discussion is where your case report either becomes a meaningful contribution or falls flat. This section needs to accomplish three things: place your case in the context of existing literature, explain what’s new or different about it, and articulate what other clinicians can learn from it.
Start by briefly restating the key features that make your case unusual. Then walk through the relevant published literature, comparing and contrasting other reported cases with yours. Where does your case align with what’s known? Where does it diverge? If your patient responded to a treatment that typically fails, or presented with symptoms not previously linked to the diagnosis, spell that out explicitly.
Be honest about limitations. If your follow-up period was short, if certain tests weren’t performed, or if the diagnosis remains uncertain, say so. Reviewers respect transparency and will flag unacknowledged weaknesses regardless. End the discussion with a concise paragraph stating the practical lessons, without references. This is your conclusion, and it should give a busy clinician a reason to remember your case.
Getting Patient Consent Right
You cannot publish a case report without the patient’s informed consent, and this step needs to happen early in the process. The consent form should include the patient’s name, the name of the person signing (which may be a legal representative if the patient lacks capacity, is a minor, or is deceased), and clear language explaining that consent covers publication and any future uses of the report.
The form should also state that consent can be withdrawn before publication but not after, and it should acknowledge that while every effort will be made to protect privacy, there is an inherent risk the patient could be identified from the clinical details. Ideally, the patient or their representative should see the final manuscript before submission. If that isn’t possible, the consent form must specify what the patient did see and that they agreed to publication without reviewing the final version. Keep a record of who obtained consent and their contact details.
De-identification goes beyond removing the patient’s name. Strip out dates that could identify them, avoid photographs showing recognizable features unless the patient specifically consents, and omit any demographic details that aren’t clinically relevant.
Navigating Authorship
Authorship disputes can sour an otherwise productive collaboration, so clarify roles upfront. The International Committee of Medical Journal Editors (ICMJE) defines four criteria that all must be met for someone to qualify as an author: they made substantial contributions to the conception, design, or data interpretation of the work; they helped draft or critically revise the manuscript; they approved the final version; and they agreed to be accountable for all aspects of the work.
As the student doing most of the writing, you’ll typically be first author. Your supervising attending or resident who managed the case will often be last or senior author. Anyone who contributed intellectually, such as a radiologist who helped interpret unusual imaging or a pathologist who identified a rare finding, may warrant co-authorship if they meet all four criteria. People who simply cared for the patient or provided general mentorship belong in the acknowledgments section, not the author list. Have this conversation with your mentor before you start writing.
Using AI Tools Responsibly
If you use a large language model to help draft, edit, or translate any portion of your manuscript, you need to understand your target journal’s disclosure policy. Most major publishers do not allow AI tools to be listed as co-authors, because authorship requires accountability, which software cannot provide. You, as the human author, bear full responsibility for every claim in the manuscript.
Many publishers distinguish between “AI-assisted” writing (where you wrote the content but used a tool to refine grammar or phrasing) and “AI-generated” content (where the tool produced original text or images). AI-assisted work may not require disclosure at some journals, but AI-generated content almost always does. You’ll need to specify exactly where AI-generated material appears in the manuscript. Check your target journal’s submission guidelines before you begin, as policies vary. Regardless of what a journal requires, always review AI-produced text line by line. These tools fabricate citations, misstate clinical facts, and generate plausible-sounding but inaccurate claims routinely.
Choosing a Journal and Submitting
Some journals are particularly welcoming to medical student authors. BMJ Case Reports is one of the most well-known outlets dedicated exclusively to case reports, and many institutions pay for fellowship memberships that waive submission fees for their students. Check with your medical school library to see if such an arrangement exists at your institution.
Beyond dedicated case report journals, many specialty journals accept case reports as a secondary article type. If your case involves a cardiology finding, for instance, search for cardiology journals that list “case reports” in their article types. Matching your case to a journal’s clinical focus increases your chances of acceptance and puts your work in front of the readers most likely to benefit from it.
Before submitting, format your manuscript exactly to the journal’s specifications. This includes word limits, reference style, figure resolution, and the inclusion of your CARE checklist (many journals require you to submit it alongside the manuscript). Have your co-authors review and formally approve the final version, then designate one person as the corresponding author to handle all communication with the journal. Peer review for case reports typically takes four to twelve weeks, and most submissions require at least one round of revisions before acceptance.
