Symptoms
Cyclosporine is effective for many patients. Azathioprine and cyclophosphamide are also immunosuppressive drugs that have been used to treat PG. In recent years drugs known as tumor necrosis factor inhibitors have been used very successfully to treat pyoderma gangrenosum. Infliximab and adalimumab have been most successful.
Causes
In a study of 103 patients with pyoderma gangrenosum, 20% of the patients had hematologic disorders, and 19% of the patients had seronegative arthritis. [4][5][6]
Prevention
It's often associated with autoimmune diseases such as ulcerative colitis, Crohn's disease and arthritis. And it may have a genetic component. If you have pyoderma gangrenosum, new skin trauma, such as a cut or puncture wound, may trigger new ulcers. Certain factors may increase your risk of pyoderma gangrenosum, including: Your age and sex.
Complications
Diagnosis. No specific diagnostic tests exist for pyoderma gangrenosum. Diagnosis is made by excluding similar disorders based upon a thorough clinical evaluation, a detailed a patient history and a variety of tests such as surgical removal and microscopic evaluation of affected tissue (biopsy).

What is pyoderma gangrenosum?
Last Update: July 10, 2020. Continuing Education Activity. Pyoderma gangrenosum is an ulcerative disorder that falls into the category of neutrophilic dermatoses. Pyoderma gangrenosum should not be confused with pyogenic granuloma, a completely separate entity but with an equally ill-fitting name.
What are the pathogenesis of pyoderma gangrenosum?
It is thought to involve genetic mutations, neutrophil dysfunction, and immune/inflammatory dysregulation. Some lesions of pyoderma gangrenosum have been found to have a proliferation of clonal T-cells. In addition, inflammasomes have been postulated to be involved in the neutrophil chemotaxis that occurs in these lesions. Inflammasomes are complexes of receptors that are part of innate immune system signaling. Some cases of pyoderma gangrenosum are associated with a mutation inJanus kinase 2, which is involved in the production of several cytokines. Abnormal cytokine signaling by T cells and macrophages is likely a component of the disease process. Lesions of pyoderma gangrenosum have been found to have increased levels of inflammatory mediators. For example, IL-23 has been found to be increased in lesions of pyoderma gangrenosum. IL-23 is important in activating neutrophils and stimulating IL-17 mediated inflammation. [7]
What is the name of the disease that heals with a cribriform scar?
Lesions of pyoderma gangrenosum usually heal with a cribriform scar. One of the most important features of the disease is a phenomenon known as pathergy. Pathergy is defined as an exaggerated response to a minor skin injury or worsening of an existing wound with minimal insult or trauma.
What is pathergy skin test?

History
A 29-year-old man presented with a three-year history of a painful and recurrent left posterior calf wound. The patient had a past medical history of Factor V Leiden, chronic bilateral lower extremity deep vein thromboses, and HIV. The patient was never a smoker, but did use marijuana.
Findings
Left posterior/distal calf wound measuring 9 x 7 centimeters. The wound had erythematous undermined edges and an ulcerated center with fibrinous exudate. No bone or tendon exposure was found.
Differential Diagnoses
Arterial insufficiency, venous stasis, infection, malignancy, vasculitis, trauma, cutaneous manifestations of other inflammatory disorders.
Workup Required
Pyoderma gangrenosum is a diagnosis of exclusion. Routine workup included complete blood count, inflammatory markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), skin biopsy, and wound cultures.
Plan
Optimize wound care, avoid surgical trauma, manage pain adequately, and choose effective medical management to reduce the aberrant inflammatory response.
Treatment
Cleansing with antibacterial agents and enzymatic/autolytic debridement were done. Sharp surgical debridement was avoided due to pathergy concerns. Dressings were selected to maintain a moist wound environment and to decrease local edema. First-line therapy involved topical or oral (0.5-1mg/kg/day) corticosteroids.
