Marshall syndrome - PFAPA synonyms

Marshall syndrome, more commonly known in clinical practice as PFAPA syndrome (Periodic Fever, Aphthous stomatitis, Pharyngitis, and Adenitis), is a periodic fever disorder characterized by recurring episodes of high fever, mouth sores, sore throat, and swollen lymph nodes. While the term "Marshall syndrome" is often used to honor Dr. Gary Marshall, who first described the condition in 1987, it is distinct from the rare genetic connective tissue disorder also called Marshall syndrome (a type of Stickler syndrome), which can cause confusion in medical literature.

What are the common synonyms and names for PFAPA syndrome?

In medical literature, Marshall syndrome is most frequently referred to as PFAPA syndrome, an acronym that serves as a clinical description of the four primary diagnostic criteria: Periodic Fever, Aphthous stomatitis, Pharyngitis, and cervical Adenitis. Because the condition was first identified as a distinct entity by Dr. Gary Marshall in 1987, it is occasionally referred to as Marshall-Wilson syndrome or Marshall’s syndrome. However, clinicians strongly prefer the term PFAPA syndrome today because it is descriptive, universally recognized, and avoids confusion with other unrelated medical conditions that share the name "Marshall syndrome."

Why is there confusion regarding the name Marshall syndrome?

The primary challenge with the term Marshall syndrome is that it is a "double-named" condition in medicine. There is a separate, unrelated genetic condition involving skeletal and ocular abnormalities (often linked to collagen mutations) that is also formally called Marshall syndrome. To prevent diagnostic errors, medical geneticists and pediatric rheumatologists almost exclusively use the acronym PFAPA syndrome. When reviewing your medical records, if you see the term "Marshall syndrome," it is vital to verify whether your physician is referring to the autoinflammatory periodic fever condition (PFAPA) or the collagen-related connective tissue disorder.

How is this condition classified in major medical systems?

Medical nomenclature for PFAPA syndrome is standardized across major international databases to ensure consistency in research and clinical care. You will typically find the following identifiers:

• Orphanet: Listed under ORPHA:32488 (PFAPA syndrome).


• OMIM: While not yet fully mapped to a single gene, it is often discussed within the context of autoinflammatory diseases.


• ICD-10/11: Often coded under "Periodic fever syndromes" or symptoms such as "Periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome."

Which name should patients and caregivers use?

When communicating with healthcare providers, using the term PFAPA syndrome is the most effective way to ensure your medical team understands exactly which condition you are discussing. In the DiseaseMaps.org community, where 7 members have documented their experiences with Marshall syndrome - PFAPA, the consensus is that using the acronym helps avoid confusion during referrals to specialists like pediatric rheumatologists or immunologists. Using the full descriptive name—Periodic Fever, Aphthous stomatitis, Pharyngitis, and Adenitis—is also highly recommended when speaking with school nurses, teachers, or insurance providers who may not be familiar with the clinical acronym.

Next steps

• Consult a pediatric rheumatologist or an infectious disease specialist to confirm your diagnosis and rule out other periodic fever syndromes.


• Use the term "PFAPA syndrome" in all new medical documentation to ensure clarity.


• Connect with the 7 members of the DiseaseMaps.org community who share this diagnosis to learn about symptom management strategies.


• Keep a detailed fever log, as it is the primary diagnostic tool used by physicians to track the periodicity of your episodes.
