Short answer · Medically reviewed summary · Last updated: 2026-05-08
Pyoderma gangrenosum is a rare, inflammatory skin condition most commonly referred to by its modern clinical name, though it is occasionally found in medical literature as "dermatitis ulcerosa" or "phagedenic pyoderma." While the name "pyoderma gangrenosum" implies an infectious or necrotic process, it is actually a non-infectious neutrophilic dermatosis, and the term remains the standard nomenclature used by clinicians worldwide today. Why does Pyoderma Gangrenosum have multiple names? The name pyoderma gangrenosum was coined in 1930 by Brunsting, Goeckerman, and O'Leary, who mistakenly believed the condition was caused by streptococcal infection leading to gangrene. Because our understanding of the disease has evolved from an infectious theory to a systemic inflammatory and autoimmune classification, older literature often uses descriptive terms based on the appearance of the ulcers.

Why does Pyoderma Gangrenosum have multiple names?
The name pyoderma gangrenosum was coined in 1930 by Brunsting, Goeckerman, and O'Leary, who mistakenly believed the condition was caused by streptococcal infection leading to gangrene. Because our understanding of the disease has evolved from an infectious theory to a systemic inflammatory and autoimmune classification, older literature often uses descriptive terms based on the appearance of the ulcers. These historical names are now rarely used in modern clinical practice, as they do not accurately reflect the underlying pathology of pyoderma gangrenosum.
What are the common synonyms and historical terms?
When searching medical databases or reviewing older patient records, you may encounter several alternative labels. While pyoderma gangrenosum is the preferred term, the following names have historically appeared in clinical documentation:
- Dermatitis ulcerosa: Used in older European literature to describe the necrotic skin appearance.
- Phagedenic pyoderma: A term referencing the rapid, "eating away" nature of the tissue destruction.
- Neutrophilic dermatosis: A broader diagnostic category that includes pyoderma gangrenosum alongside conditions like Sweet syndrome.
- PG: The standard medical abbreviation used in charts and clinical research papers.
How is Pyoderma Gangrenosum classified officially?
Major international classification systems have standardized the diagnostic terminology to ensure consistency in research and care. In the International Classification of Diseases (ICD-11), it is listed under "Neutrophilic dermatoses." Orphanet (ORPHA:791) and the NIH Genetic and Rare Diseases (GARD) database both categorize the condition explicitly as pyoderma gangrenosum. Using this official name is recommended when communicating with insurance providers or specialists to ensure accurate tracking and access to resources.
