Polyarteritis Nodosa synonyms

Polyarteritis Nodosa (PAN) is a systemic necrotizing vasculitis that primarily affects medium-sized arteries, and it is most commonly referred to by this name in modern clinical practice. Historically, it has been known by several synonyms, including Kussmaul-Maier disease and periarteritis nodosa, though these are now largely considered outdated or imprecise.

What are the common synonyms for Polyarteritis Nodosa?

While Polyarteritis Nodosa is the standard medical term, you may encounter older or alternative names in medical records or historical literature. Historically, the condition was described as periarteritis nodosa, a term that became less accurate once researchers realized the inflammation affects the entire thickness of the arterial wall rather than just the outer layer. Other historical terms include Kussmaul-Maier disease, named after the physicians who first described the condition in 1866. In some international contexts or older textbooks, you might see it referred to as infantile polyarteritis nodosa, though this specific pediatric presentation is now classified separately in most modern rheumatological frameworks.

How is Polyarteritis Nodosa classified in medical systems?

Standardized nomenclature is essential for clinical consistency. Current classification systems typically use the following identifiers for Polyarteritis Nodosa:

• Orphanet: ORPHA683


• OMIM: #615598


• ICD-10: M30.0 (Polyarteritis nodosa)

Why does Polyarteritis Nodosa have multiple names?

The variety of names for Polyarteritis Nodosa stems from the evolution of pathology and medical imaging. As our understanding of how Polyarteritis Nodosa impacts the immune system and blood vessels has deepened, nomenclature has shifted from descriptive terms (like "periarteritis") to more accurate pathological definitions. Currently, the Chapel Hill Consensus Conference (CHCC) nomenclature is the global gold standard, which firmly establishes Polyarteritis Nodosa as the preferred term to distinguish it from other forms of vasculitis, such as microscopic polyangiitis.
