Background
Subtypes
- Ulcerative: ulceration with rapidly-evolving purulent wound
- Pustular: discrete pustules, sometimes self-limited, and most commonly associated with inflammatory bowel disease
- Bullous: superficial bullae with ulcerations
- Vegetative: erosions with superficial ulcers
Associated Disorders
- Inflammatory bowel disease (40% of cases with a known association), ulcerative colitis more than Crohn disease
- Inflammatory arthritis (20%), particularly seronegative rheumatoid arthritis or spondylitis
- Solid organ malignancy (5-10%)
- Hematologic malignancy (5-10%)
- Other hematologic disorder (5%), including MGUS/myeloma, myelodysplastic syndrome, or polycythemia vera, lymphoma, leukemia
- Rarely, hepatitis C
- Idiopathic in about 50% of cases
Clinical Manifestations
- Chronic wound, most commonly on lower legs in the pretibial area
- Can occur anywhere on the body, particularly at surgical sites
- Rarely, can involve upper airway, eye, genital mucosa, lung (sterile neutrophilic pulmonary infiltrates), splenic infiltrates, myositis, and sterile osteolysis
Diagnosis
Diagnostic Criteria1
- Major criterion:
- Biopsy of ulcer edge demonstrating a neutrophilic infiltrate
- Minor criteria:
- Exclusion of infection
- Pathergy
- Personal history of inflammatory bowel disease or inflammatory arthritis
- History of papule, pustule, or vesicle that rapidly ulcerated
- Peripheral erythema, undermining border, and tenderness at site of ulceration
- Multiple ulcerations (at least one occurring on an anterior lower leg)
- Cribriform or "wrinkled paper" scar(s) at sites of healed ulcers
- Decrease in ulcer size within one month of initiating immunosuppressive medications
- Interpretation:
- Positive if at the major criterion and at least four minor criteria are present
