Abstract
Pyoderma gangrenosum (PG) is a skin lesion, characteristically a neutrophilic dermatosis, that can be complicated by rapid progression, necrosis, and ulceration. This is an important pathology to be discussed given that there are no established criteria for diagnosis or treatment. This review aims to elucidate characteristics and variations of PG that distinguish it from other ulcerative skin lesions. Variability in presentation can lead to missed or incorrect diagnosis, and some of the currently proposed criteria for categorizing and diagnosing PG have been included here. These criteria distinguish PG in terms of the nature of the lesion, the location, etiology, responsiveness to immunosuppressive therapy, and patient history. The etiology and pathogenesis of PG remain unknown, but we summarize prominent theories and explanations. Furthermore, recent research indicates that the incidence of PG has a strong correlation with autoimmune conditions, particularly inflammatory bowel disease. Major treatments for PG coincide with these findings, as the majority involve targeted anti-inflammatories, immunosuppressants, and surgical interventions. These treatments are addressed in this review, with added context for local versus systemic disease.

Abstract
Pyoderma gangrenosum (PG) is a debilitating skin condition often accompanied by inflammatory bowel disease (IBD). Strikingly, ~40% of patients that present with PG have underlying IBD, suggesting shared but unknown mechanisms of pathogenesis. Impeding the development of effective treatments for PG is the absence of an animal model that exhibits features of both skin and gut manifestations. This study describes the development of the first experimental drug-induced mouse model of PG with concomitant intestinal inflammation. Topical application of pyrimidine synthesis inhibitors on wounded mouse skin generates skin ulcers enriched in neutrophil extracellular traps (NETs) as well as pro-inflammatory cellular and soluble mediators mimicking human PG. The mice also develop spontaneous intestinal inflammation demonstrated by histologic damage. Further investigations revealed increased circulating low density IL-1β primed neutrophils that undergo enhanced NETosis at inflamed tissue sites supported by an increase in circulatory citrullinated histone 3, a marker of aberrant NET formation. Granulocyte depletion dampens the intestinal inflammation in this model, further supporting the notion that granulocytes contribute to the skin-gut crosstalk in PG mice. We anticipate that this novel murine PG model will enable researchers to probe common disease mechanisms and identify more effective targets for treatment for PG patients with IBD.

Abstract
Pyoderma gangrenosum (PG) is a reactive, non-infectious inflammatory neutrophilic dermatoses that have historically presented as a diagnostic and therapeutic dilemma. It is often misdiagnosed as other disease processes, particularly ulcers, and is thus associated with a delay in care. Pyoderma gangrenosum, left untreated, carries a three times mortality risk compared to the general population. There are multiple subtypes and presentations reflected in the current research which shows that there is still much to be understood about this disorder. Here we examine the unique presentation of a vegetative type of pyoderma gangrenosum through the case of a 69-year-old male that presents with a persistent lesion on his foot.

Abstract
Negative-pressure wound therapy has been shown to be effective in re-epithelialisation in recalcitrant pyoderma gangrenosum. This case documents a patient whose co-morbidities limited the standard treatment options and required an alternative management plan. The STOP GAP randomised control trial found that both oral prednisolone and ciclosporin were equally effective in the treatment of pyoderma gangrenosum. However, in this case, the patient had type 2 diabetes and prednisolone resulted in persistently elevated blood glucose levels. Lower doses were ineffective and it was subsequently stopped once other treatments showed a clinical improvement. A recent diagnosis of breast cancer prevented the use of ciclosporin and other immunosuppressive treatments. After multidisciplinary discussion, involving breast surgeons, oncology, dermatology and tissue viability, doxycycline was commenced alongside a portable negative-pressure device with twice weekly tissue viability input. The introduction of this device resulted in a rapid reduction in the wound size and facilitated healing with an excellent outcome.

Abstract
BACKGROUND Pyoderma gangrenosum (PG) is a rare ulcerative skin disease; its etiology is unknown, though it is often associated with autoimmune diseases. Pyoderma gangrenosum results in significant morbidity and exquisite pain that affects health-related quality of life. Wound healing is delayed, and patients often experience relapse. Pyoderma gangrenosum is susceptible to pathergy and deterioration with surgical intervention or other trauma; therefore, treatment includes atraumatic wound care, infection management, and local or systemic immunosuppression. CASE We describe the use of modified negative pressure wound therapy (NPWT) with intralesional and topical steroids for the treatment of PG in a 15-year-old female patient with ulcerative colitis and a staged J-pouch ileoanal reconstruction. The patient and her family refused all systemic therapy due to prior steroid-associated weight gain. She was unable to tolerate conscious dressing changes, further complicating the treatment plan. Procedural interventions such as NPWT have been used previously for PG; however, they can cause wound pathergy and subsequent wound deterioration. Modified NPWT in conjunction with topical and intralesional steroids induced wound healing without producing pathergy. CONCLUSION Timely recognition of PG is crucial to appropriate delivery of care. Modified NPWT and localized corticosteroid treatment were key to promoting wound healing in this case of pediatric PG.

Abstract
Pyoderma gangrenosum (PG) is a rare, reactive, non-infectious inflammatory dermatosis. It typically presents with extensive cutaneous ulcerations. A 20-year-old lady presented with a painful, progressive, non-healing ulcer with purulent discharge on the right upper thigh. Debridement of the ulcer was done, and pus was sent for culture and sensitivity. Despite regular wound care, the ulcer was progressing in size with persistent pain. The ulcer exhibited the phenomenon of pathergy. The pus was sterile on examination, and the histopathology showed extensive neutrophilic infiltration. A history of similar non-healing ulcers in a family member pointed toward the diagnosis of this rare condition. Treatment of pyoderma gangrenosum started in conjunction with the dermatology department. After appropriate wound care with systemic steroids and immunomodulators, the ulcer healed by secondary intention. PG is a diagnosis of exclusion. A high level of suspicion of an uncommonly presenting ulcer would lead to early diagnosis and appropriate treatment. Early diagnosis and treatment with corticosteroids and immunosuppressants can heal the lesion early by minimizing pathergy.

Abstract
Pyoderma gangrenosum (PG) is a sterile inflammatory neutrophilic dermatosis that can present as a peristomal, pustular, bullous, vegetative, or ulcerative variant. It commonly affects the lower extremities, mainly in the pretibial area. We describe a case of extensive PG in an 18-year-old Indonesian man, involving the upper third of the body. Dermatological examination showed multiple painful ulcers with violaceous borders on the face, occipital region of scalp, neck, shoulder, upper chest, and back. The diagnosis of PG was established based on the histopathological examination that revealed massive dermal neutrophilic infiltration mixed with lymphocytic inflammatory infiltrates accompanied by leukocytoclastic vasculitis. The patient was treated with methylprednisolone equivalent to 1 mg/kg/day of prednisone. An excellent response to therapy also confirmed the diagnosis of PG. Since lesions of PG can appear on any part of the body, including the upper third of the body, a complete and appropriate examination is useful in establishing diagnosis.

Abstract
Since their discovery, glucocorticoids (GCs) have been used to treat almost all autoimmune and chronic inflammatory diseases, as well as allergies and some forms of malignancies, because of their immunosuppressive and anti-inflammatory effects. Although GCs provide only symptomatic relief and do not eliminate the cause of the pathology, in the majority of treatments, GCs frequently cannot be replaced by other classes of drugs. Consequently, long-term treatments cause adverse effects that may, in turn, lead to new pathologies that sometimes require the withdrawal of GC therapy. Therefore, thus far, researchers have focused their efforts on molecules that have the same efficacy as that of GCs but cause fewer adverse effects. To this end, some GC-induced proteins, such as glucocorticoid-induced leucine zipper (GILZ), have been used as drugs in mouse models of inflammatory pathologies. In this review, we focus on some important but rare autoimmune and chronic inflammatory diseases for which the biomedical research investment in new therapies is less likely. Additionally, we critically evaluate the possibility of treating such diseases with other drugs, either GC-related or unrelated.

Abstract
Pyoderma gangrenosum is a rare, neutrophil-mediated, auto-inflammatory dermatosis that wound care specialists must be prepared to recognise. This condition has clinical features analogous to infectious processes. There is no specific diagnostic test and the diagnosis is usually obtained from exclusion. Its early recognition and proper management with prompt initiation of immunosuppressive therapy are essential to improve the quality of life and the prognosis of patients.
