Pyoderma gangrenosum is an uncommon, ulcerative cutaneous condition of uncertain etiology (cause). It is associated with systemic autoimmune related diseases in at least 50% of patients who are affected. The diagnosis is made by excluding other causes of similar-appearing cutaneous ulcerations, including infection, malignancy, vasculitis, collagen vascular diseases, diabetes, and trauma. In a process termed pathergy, new ulcerations may occur after trauma or injury to the skin in 30% of patients who already have pyoderma gangrenosum. The prognosis of pyoderma gangrenosum is generally good; however, the disease may recur, and residual scarring is common. Pain is a common complaint of patients and may require narcotics.
Pyoderma gangrenosum is a rare, destructive inflammatory skin disease of which a painful nodule or pustule breaks down to form a progressively enlarging ulcer. Lesions may occur either in the absence of any apparent underlying disorder or in association with other diseases, such as ulcerative colitis, Crohn’s disease, polyarthritis (an inflammation of several joints together), gammopathy, vasculitis, leukemia, and other conditions.[1][2][3] Each year in the United States, pyoderma gangrenosum occurs in about 1 person per 100,000 people.[1]
Pyoderma gangrenosum belongs to a group of autoinflammatory skin diseases called neutrophilic dermatoses.[2][3][4] Neutrophils are a type of white blood cell or leukocyte which form an early line of defense against bacterial infections.[5] Ulcerations associated with pyoderma gangrenosum may occur after trauma or injury to the skin, a process called pathergy.[1][2] Treatment involves wound care and the use of anti-inflammatory agents, including antibiotics, corticosteroids, immunosuppressants, and biologics.
Types of Pyoderma Gangrenosum
There are different types of pyoderma gangrenosum, but they all share similar characteristics. The most common type is the classic form, but there are also atypical and ulcerative forms, each with its unique features.
Causes of Pyoderma Gangrenosum
Possible Causes
- Autoimmune disorders: When the body’s immune system attacks its own skin.
- Inflammatory bowel disease: Conditions like Crohn’s disease and ulcerative colitis.
- Rheumatoid arthritis: An autoimmune joint disorder.
- Blood disorders: Such as leukemia or myeloma.
- Infections: Like streptococcal or viral infections.
- Medications: Some drugs can trigger pyoderma gangrenosum.
- Surgical procedures: Wounds from surgeries can develop pyoderma gangrenosum.
- Trauma or injury: Skin injuries may lead to this condition.
- Pregnancy: It can occur during or after pregnancy.
- Genetic factors: It may have a genetic component.
- Vaccinations: In rare cases, vaccines can be a trigger.
- Insect bites: Severe reactions can lead to pyoderma gangrenosum.
- Skin conditions: Like acne or hidradenitis suppurativa.
- Behcet’s disease: A rare inflammatory condition.
- Sarcoidosis: An autoimmune disorder affecting multiple organs.
- Wegener’s granulomatosis: A type of vasculitis.
- HIV/AIDS: Can increase the risk.
- Hepatitis: Particularly hepatitis C.
- Crohn’s-related arthritis: Associated with Crohn’s disease.
- Undetermined causes: In some cases, the cause remains unknown.

Diagnostic Tests
Common Diagnostic Tests
