Abstract
Pyoderma gangrenosum (PG) is a rare, neutrophilic skin disease. For the purpose of accurate diagnosis and proper treatment of PG, the Japanese clinical practice guidance for PG developed by the Japanese Dermatological Association was published in 2022. In this guidance, clinical aspects, pathogenesis, current therapies, and clinical questions on PG are described from the viewpoints of current knowledge and evidence-based medicine. Here, the English version of the Japanese clinical practice guidelines for PG is presented and is intended to be widely referred to in the clinical examination and treatment of PG.

Abstract
Pyoderma gangrenosum (PG) is a skin disease characterized by painful ulcers that, when not appropriately treated, can lead to permanent disfigurement. Pyoderma gangrenosum has been observed in a multitude of autoimmune disorders such as rheumatoid arthritis, inflammatory bowel disease (IBD), and sarcoidosis (Feld et al. J Rheumatol. 39(1):197, 2012; Herrero et al. J Rheumatol. 36:7:1557-1558, 2009). It is rarely associated with autoimmune disorders such as systemic sclerosis. We report a case of a patient with known limited cutaneous systemic sclerosis who developed an ulcerated lesion on the 2nd digit of the left hand. The lesion was initially thought to be cellulitis and the patient underwent superficial wound debridement. Postoperatively, the patient's lesions worsened. The patient was treated with intravenous (IV) methylprednisolone and 0.05% topical clobetasol due to high suspicion for PG with complete resolution of ulcerated lesions and minimal scarring.

Abstract
Pyoderma gangrenosum (PG) is a rare disease of unknown aetiology, first described over a century ago. Initially thought to have an infectious cause, and now primarily considered an autoinflammatory condition, PG continues to be poorly understood, commonly misdiagnosed, and difficult to treat. In this review, we discuss the journey of our understanding of PG to date, including first descriptions, challenges with diagnosis, presumed pathogenesis, and treatments used. We highlight major historical landmarks and their importance, explain the rationale behind current investigations, note outstanding gaps in knowledge, and explore the future directions of PG research. We summarise what we have known, what we are working on knowing, and what we have yet to explore about PG, illustrating overall trends to invigorate future research.

Abstract
Background: Pyoderma gangrenosum (PG) in inflammatory bowel disease (IBD) is a rare cutaneous condition and its treatment remains controversial due to limited data. Aims and Objectives: The purpose of this study was to investigate the characteristics and treatment response to specific therapies of IBD-associated PG. Methods: In this retrospective study, we reviewed a series of cases of IBD-associated PG patients who presented at our institution, and collected clinical data, such as demographics, characteristics, subtype, and disease activity of IBD and specific therapies used and their treatment response. Results: In total, 42 cases were identified: 69% female and 92.9% with ulcerative colitis (UC). At PG diagnosis, 93% had active and 7% inactive IBD. PG ulcers occurred predominantly on the legs (33.3%); 14.3% had multiple lesions. In total, 20/39 UC patients received the combination therapy of systemic corticosteroids and 5-aminosalicylic acid (5-ASA) with a good response in 19 patients (95%). Seven patients received the monotherapy of 5-ASA with a response rate of 43%. Five patients were successfully treated with systemic corticosteroids alone. Other patients were treated with intravenous immunoglobulin, infliximab, or cyclophosphamide alone or in combination with corticosteroids and all showed a good response. Conclusion: Our study indicates the therapeutic efficacy of corticosteroids in combination with 5-ASA, which may be considered as the first-line therapy for UC-associated PG.

Abstract
Pyoderma gangrenosum (PG) is a reactive non-infectious inflammatory dermatosis falling under the spectrum of the neutrophilic dermatoses. There are several subtypes, with 'classical PG' as the most common form in approximately 85% cases. This presents as an extremely painful erythematous lesion which rapidly progresses to a blistered or necrotic ulcer. There is often a ragged undermined edge with a violaceous/erythematous border. The lower legs are most frequently affected although PG can present at any body site. Other subtypes include bullous, vegetative, pustular, peristomal and superficial granulomatous variants. The differential diagnosis includes all other causes of cutaneous ulceration as there are no definitive laboratory or histopathological criteria for PG. Underlying systemic conditions are found in up to 50% of cases and thus clinicians should investigate thoroughly for such conditions once a diagnosis of PG has been made. Treatment of PG remains largely anecdotal, with no national or international guidelines, and is selected according to severity and rate of progression. Despite being a well-recognised condition, there is often a failure to make an early diagnosis of PG. This diagnosis should be actively considered when assessing ulcers, as prompt treatment may avoid the complications of prolonged systemic therapy, delayed wound healing and scarring.

Abstract
INTRODUCTION Pyoderma gangrenosum (PG) is a complex neutrophilic dermatosis that can occur as an idiopathic disease, in association with systemic conditions such as inflammatory bowel disease, as part of an inherited inflammatory syndrome. It can be challenging to treat, as it occurs in a wide variety of clinical settings and there is a lack of a standardized treatment approach. The main limitations to treatment have been an incomplete understanding of the pathogenesis. However, recent advances have been made in understanding the pathogenesis of this condition, and PG is now considered an autoinflammatory disease process. Areas covered: This review discusses the newest studies that further define our understanding of this disease and the relevant literature on treatment options for pyoderma gangrenosum. Expert commentary: The presence of abnormal neutrophils and T-cells lead to immune dysregulation, leading to lesions of PG. Increased levels of inflammatory mediators including IL-1β, IL-8, IL-17, and TNF-α contribute to the development of the disease but there are still several unknown factors, including the trigger for immune dysregulation and additional contributory components of the immune system. We provide our approach to the management of PG lesions, which involves a multi-faceted approach including wound care, topical therapy, and systemic medications in most cases.

Abstract
Pyoderma gangrenosum (PG) is a rare autoinflammatory condition in which the alteration of neutrophil function and the innate immune response play key roles in its pathogenesis. Cases of PG have been reported in patients being treated with certain medications, which may help us to understand some of the possible pathways involved in the aetiology of PG. The aim of this review is to review the cases of PG triggered by certain drugs and try to thoroughly understand the pathogenesis of the disease. To accomplish this, a PubMed search was completed using the following words: pyoderma gangrenosum, neutrophilic dermatosis, pathophysiology, drug-induced pyoderma gangrenosum. In total, we found 43 cases of drug-induced PG. Most of them were caused by colony-stimulating factors and small-molecule tyrosine kinase inhibitors. We propose that drugs induce PG through various mechanisms such as dysfunctional neutrophil migration and function, dysregulated inflammatory response, promotion of keratinocyte apoptosis and alteration of epigenetic mechanisms. PG is a rare condition with complex pathophysiology and drug-induced cases are even more scarce; this is the main limitation of this review. Understanding the possible mechanisms of drug-induced PG, via abnormal neutrophil migration and function, abnormal inflammation, keratinocyte apoptosis and alteration of epigenetic mechanisms would help to better understand the pathogenesis of PG and ultimately to optimize targeted therapy.

Abstract
A 66-year-old woman presented after an episode of accidental trauma with a painful ulcer on her scalp which rapidly enlarged in size, accompanied by central necrosis and undermining ulceration. The patient's past history was negative for underlying systemic disease, although she had had a similar post-traumatic intractable leg ulcer 3 years prior, which was unresponsive to surgical management but successfully treated with systemic steroids. A biopsied specimen from the scalp showed marked neutrophilic infiltrates in the dermis, compatible with a diagnosis of pyoderma gangrenosum (PG). The large ulcerative lesion responded very well to oral steroid therapy, showing rapid epithelialization. Serum levels of granulocyte colony-stimulating factor and interleukin-6 were significantly elevated prior to treatment, with decrease to normal levels after treatment. Serum tumor necrosis factor (TNF)-α and granulocyte macrophage colony-stimulating factor levels were within normal limits. The significance and pathogenic role of cytokine burst in PG is reviewed and discussed.

Abstract
Pyoderma gangrenosum (PG) and Sweet's syndrome (SS) are two inflammatory skin diseases presenting with painful ulcers and erythematous plaques, respectively; both disorders have a debilitating clinical behaviour and PG is potentially life-threatening. Recently, PG and SS have been included among the autoinflammatory diseases, which are characterized by recurrent episodes of sterile inflammation, without circulating autoantibodies and autoreactive T cells. However, an autoinflammatory pattern clearly supporting this inclusion has never been demonstrated. We studied 16 patients with PG, six with SS and six controls, evaluating, using a sandwich-based protein antibody array method, the expression profile of inflammatory effector molecules in PG, SS and normal skin. The expressions of interleukin (IL)-1 beta and its receptor I were significantly higher in PG (P = 0·0001 for both) and SS (P = 0·004-0·040) than in controls. In PG, chemokines such as IL-8 (P = 0·0001), chemokine (C-X-C motif) ligand (CXCL) 1/2/3 (P = 0·002), CXCL 16 (P = 0·003) and regulated upon activation normal T cell expressed and secreted (RANTES) (P = 0·005) were over-expressed. In SS, IL-8 (P = 0·018), CXCL 1/2/3 (P = 0·006) and CXCL 16 (P = 0·036) but not RANTES were over-expressed, suggesting that chemokine-mediated signals are lower than in PG. Fas/Fas ligand and CD40/CD40 ligand systems were over-expressed in PG (P = 0·0001 for Fas, P = 0·009 for Fas ligand, P = 0·012 for CD40, P = 0·0001 for CD40 ligand), contributing to tissue damage and inflammation, while their role seems to be less significant in SS. Over-expression of cytokines/chemokines and molecules amplifying the inflammatory network supports the view that PG and SS are autoinflammatory diseases. The differences in expression profile of inflammatory effectors between these two disorders may explain the stronger local aggressiveness in PG than SS.

Abstract
Pyoderma gangrenosum (PG) is an uncommon ulcerative skin disease often associated with underlying systemic diseases. Its pathogenesis is unknown, although immune pathways have been implicated. Targeted therapy is therefore lacking and currently treatment is largely empirical and consists of corticosteroids and ciclosporin first line. This paper reviews the current and emerging knowledge about PG. PG occurs with an incidence of 3-10 per million per year. The ulcers are exquisitely painful and characteristically have a necrotic centre with irregular overhanging bluish borders. Around half of cases are associated with underlying systemic disease, most commonly inflammatory bowel disease, rheumatoid arthritis and haematological malignancies; the remaining cases are idiopathic. The pathogenesis is unknown, but the most widely supported theory is immunological, and biopsies of lesions show a predominantly neutrophilic infiltrate. Several aberrant immune processes have been described, with neutrophils and their recruitment to sites of inflammation by cytokines taking an apparently important role. Topical and systemic therapies are both vital aspects of treatment, and in recent years, immune modulators have been used with increasing success, with an emerging role for anti-tumour necrosis factor alpha agents such as the monoclonal antibody infliximab. Although uncommon, PG causes significant morbidity to those it affects. Further research is needed into the disease pathogenesis, and adequate targeted treatment.

Abstract
BACKGROUND Pyoderma gangrenosum (PG) in inflammatory bowel disease (IBD) is uncommon and therapeutically challenging. Its treatment remains poorly characterised due to limited individual centre or practitioner experience. No large series are reported since 2003, yet IBD treatment has changed substantially. AIM To provide an up-to-date review of the published treatment efficacy of currently available therapies for IBD-related PG in the biologic era. METHODS Systematic review of cases published post-2003 since the broad availability of anti-tumour necrosis factor-alpha (TNFα) therapy. Cases which did not have coexistent IBD, were non-English language, of paediatric age or without data on response to therapy were excluded. RESULTS Sixty cases were identified; 55% female, 50% UC, 45% CD, 5% IBD-U. At PG diagnosis, 58% had active and only 15% inactive IBD, with 27% with IBD activity unspecified. Predominant sites were lower limb (48%) and peristomally (25%); 42% had multiple lesions. In 12%, trauma preceded PG. In 42%, new PG appeared whilst on IBD-specific therapy, whilst 28% were on no therapy and in 30%, IBD therapy was unspecified. Of patients on no therapy at PG onset (n = 17), 16 healed; seven with first- and eight with second-line therapy. In total, 34/60 patients received infliximab, four received adalimumab, two had both; with 33 (92%) responding to one or the other. There was no correlation of PG duration or size with healing times. CONCLUSIONS Pyoderma gangrenosum appears predominantly during active IBD and is seen equally in CD and UC. New PG may be a manifestation of recrudescent IBD or it follow trauma. Anti-TNFα therapy as a first-line agent for PG should be considered, as it appears to be highly effective.

Abstract
Although they may sometimes appear similar, paraneoplastic autoimmunity has a unique pathogenesis, different from the classical autoimmune diseases not associated with cancer. When distinguished clinically, paraneoplastic autoimmunity is more severe and often presents with a broader range of clinical signs and symptoms. Management of these patients is difficult and is usually centered in part on treatment of the underlying malignancy. Self-antigens recognized in the setting of paraneoplastic autoimmunity can be diverse, and the number of determinants recognized within a single antigen can be numerous. This review uses prototypic examples of paraneoplastic immune-mediated diseases and their associated malignancies to describe the mechanisms by which immune dysregulation can occur in the setting of cancer. Specific diseases covered include paraneoplastic pemphigus, Sweet's syndrome, pyoderma gangrenosum, thymoma-associated multiorgan autoimmunity, myasthenia gravis, autoimmune hemolytic anemia, immune thrombocytopenia, and the paraneoplastic neurological syndromes. The malignancies discussed include thymoma, non-Hodgkin's lymphoma, and chronic lymphocytic leukemia, among others. The mechanisms by which cancers induce autoimmunity are broken down into the following categories: disruption of central tolerance, peripheral immune dysregulation, and alteration of self-antigens. For each category, examples of paraneoplastic autoimmune diseases and their associated malignancies are discussed. Finally, mechanisms by which cancer treatment can lead to autoimmunity and examples of polymorphisms that are linked to both cancer and autoimmunity are discussed.

Abstract
Pyoderma gangrenosum (PG) manifests as recurrent deep ulceration of the skin and PG is associated with a variety of disorders. Approximately 30% of the cases of PG develop in patients with inflammatory bowel disease. A 34-year-old woman presented with a one-week history of recurrent ulcers on the right cheek and back. She was diagnosed with ulcerative colitis (UC) 4 years previously and with PG 1 year previously. The clinical course of the skin lesions followed the status of her UC. The patient's skin lesions and bowel symptoms were not improved with prednisolone. After she was started on mesalazine, we observed rapid resolution of skin lesions and bowel symptoms. Herein, we report a case of recurrent PG with UC, and we discuss the possible association between these two conditions, and the efficacy of mesalazine therapy for the treatment of PG combined with UC.

Abstract
Pyoderma gangrenosum (PG) is a rare, immune-mediated inflammatory skin disease presenting with painful ulcers having undermined edges. Less commonly, bullous and vegetative variants exist. Histology consists of a neutrophil-rich dermal infiltrate. We characterized immunohistochemically the infiltrate in different variants of PG and in another neutrophilic dermatosis as Sweet's syndrome. We studied 21 patients with PG, eight with Sweet's syndrome and 20 controls, evaluating skin immunoreactivity for inflammatory cell markers (CD3, CD163 and myeloperoxidase), cytokines [tumour necrosis factor (TNF)-α, interleukin (IL)-8 and IL-17], metalloproteinases (MMP-2 and MMP-9) and vascular endothelial growth factor (VEGF). Immunoreactivities of CD3, CD163, myeloperoxidase, TNF-α, IL-8, IL-17, MMP-2, MMP-9 and VEGF were significantly higher in both PG and Sweet's syndrome than in controls (P=0·0001). Myeloperoxidase (neutrophil marker), IL-8 (cytokine chemotactic for neutrophils) and MMP-9 (proteinase-mediating tissue damage) were expressed more significantly in both ulcerative and bullous PG than in vegetative PG as well as in Sweet's syndrome (P=0·008-P=0·0001). In ulcerative PG, the expression of CD3 (panT cell marker) and CD163 (macrophage marker) were significantly higher in wound edge than wound bed (P=0·0001). In contrast, the neutrophil marker myeloperoxidase was expressed more significantly in wound bed than wound edge (P=0·0001). Our study identifies PG as a paradigm of neutrophil-mediated inflammation, with proinflammatory cytokines/chemokines and MMPs acting as important effectors for the tissue damage, particularly in ulcerative and bullous PG where damage is stronger. In ulcerative PG, the wound bed is the site of neutrophil-recruitment, whereas in the wound edge activated T lymphocytes and macrophages pave the way to ulcer formation.

[PMID: 20237982 PMCID: PMC2825530 DOI: 10.1007/s12105-009-0149-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2009] [Accepted: 10/28/2009] [Indexed: 10/20/2022]
Abstract
The aim of this study was to investigate the cellular immune profile and the expression of IL-6, IL-8 and TNF-alpha in tissue biopsies of pyostomatitis vegetans (PV). Working hypothesis was that knowledge of the cellular immune profile and role of mediators such as IL-6, IL-8 AND TNF-alpha may contribute to a better understanding of the pathogenesis of this rare entity. Archival tissues from three patients with clinically and histologically confirmed PV were studied. Analysis of the immune profile of the cellular infiltrate and expression of IL-6 and IL-8 were evaluated by immunohistochemistry. ISH was performed to evaluate the expression of TNF-alpha. Biopsy tissues from erythema multiforme, recurrent aphthous stomatitis, lichen planus and normal buccal mucosa were analyzed as controls. All patients were affected by multiple mucosal ulcerations and yellow pustules mainly located in the vestibular, gingival and palatal mucosa. Histopathologically, all specimens showed ulcerated epithelium with characteristic intraepithelial and/or subepithelial microabscesses containing abundant eosinophils plus a mixed infiltrate composed of lymphocytes and neutrophils. Cellular immune profile of the inflammatory infiltrate revealed a predominance of T-lymphocytes, mainly of cytotoxic (CD3+/CD8+) phenotype, over B-cells. CD20+ B-lymphocytes were also identified to a lesser degree among the lymphoid cells present in the lamina propria. Overexpression of IL-6 and TNF-alpha was found in both epithelial and inflammatory mononuclear cells. IL-8 expression was shown in the mononuclear cells scattered among the inflammatory infiltrate. Similar findings of overexpression of IL-6, IL-8 and TNF-alpha were, however, found in control tissues. In PV lesions, the inflammatory infiltrate shows a predominance of cytotoxic lymphocytes. Expression of IL-6, IL-8 and TNF-alpha, although not specific to PV, appears up-regulated thus these cytokines would represent a suitable therapeutic target. However, the complexity of the cytokine network and their numerous functions require further studies in order to confirm our findings.
