Abstract
INTRODUCTION Pyoderma gangrenosum (PG) is a rare, difficult-to-treat neutrophilic ulcerative cutaneous condition that severely impacts those affected. Treatment options for PG are limited, and disease remission is not guaranteed. Hyperbaric oxygen treatment is a potential therapeutic option for treating various ulcerative conditions not frequently utilized for PG. CASE REPORT We present a case of a patient with treatment-resistant PG who achieved remission with adjunctive HBOT, and then later had difficulty achieving remission without HBOT during a future flare. DISCUSSION HBOT should be more readily considered as a treatment option for those with PG.

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 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
Chronic painful ulcers caused by pyoderma gangrenosum (PG) and cutaneous vasculitis remain to be a therapeutic challenge. Skin grafts have been used with success in selected cases but are generally avoided due to the fear of pathergy. The aim of this study was to investigate the safety and efficacy of skin grafting in the treatment of primary vasculitic ulcer (PVU) and PG. MEDLINE, Embase, the Cochrane Library, Clinicaltrial.gov, and WHO International Clinical Trials Registry Platform (ICTRP) were searched from inception to March 2020. A search for grey literature was conducted in May 2020. We included studies assessing the efficacy and safety of skin grafting in the treatment of PG and PVU. Studies were only included if skin grafting was performed after establishment of PG or PVU diagnosis. A total of 721 articles was identified through the database search of which 92 were included in this study. Ten articles were identified by handsearching the reference list of included studies. Finally, 102 articles describing 212 wounds in 153 patients were included. Complete healing was found in 75.5% of the wounds. The average time to complete was 10.8 weeks (95% CI 6.1-15.6). The mean donor site healing time was 1.9 weeks (95% CI 0.52-3.20). Pathergy was reported in 8 (5.2%) patients. One patient had severe infection related to skin grafting. A statistically significant difference in the number of patients receiving preoperative (P = .0079) and postoperative (P = .002) immunosuppressive therapy was found between the groups with complete healing/reduction and no improvement/aggravation. This systematic review finds the current evidence on efficacy and safety of skin grafting in treatment of PG and PVU to be promising but limited to the size and lack of studies superior to case reports and case series. Future placebo-controlled trials are required to draw a stronger conclusion.

Abstract
Significance: Pyoderma gangrenosum (PG) is a rare debilitating autoinflammatory ulcerative skin disease. No gold standard has been established for the treatment of PG. The role of surgical interventions and negative pressure wound therapy (NPWT) was discussed controversially until recently as these procedures might pose a trigger to further aggravate the condition. Recent Advances: Recent advances confirm the paradigm change that a surgical approach of PG with split thickness skin grafting (STSG) secured by NPWT is a safe and valuable treatment if performed under adequate immunosuppression. We elaborate this on the hand of a broad literature search retrieving 101 relevant articles describing 138 patients complemented with our personal experience on 23 patients, including 2 patients treated with a porcine xenodressing. Critical Issues: A wide range of surgical approaches have been reported, including xenografts. Treatment was finally successful in 86%, including the xenotransplant cases. Ten percent improved and failures were mainly reported without immunosuppression. Despite halting the inflammatory process, NPWT alone, without skin grafting, does not much accelerate healing time. The best surgical approach appears to be STSG fixed with NPWT as this leads to higher skin graft take. There remains the problem of the chronic nature of PG and the recurrence after tapering of immunosuppression or trauma; therefore, a sustained immunosuppressive treatment is suggested. Future Directions: While surgical treatment is supported by the published data, the exact immunosuppression is still evolving. Due to deeper insights into pathogenesis and growing clinical reports, a broader utilization of biologic treatments and a shift from tumor necrosis factor (TNF)-alpha to interleukin (IL)-12/23 or IL-23 antibodies alone are predictable, as IL-12/23 antibodies show good clinical responses with fewer side effects. The positive results with porcine xenodressings might be due to immunological effects of the xenomaterial; they appear promising, but are preliminary and should be confirmed in a larger patient collective.

Abstract
This article presents the case of a rapidly progressing pyoderma gangrenosum (PG) following a minor trauma and surgical intervention. A 46-year-old patient was admitted to hospital after a minor trauma of the right lower leg with a suspected diagnosis of erysipelas bullosum. A magnetic resonance imaging (MRI) scan showed the suspicion of necrotizing fasciitis (NF) with indications for immediate incision and fascia resection. According to the results of the histopathological analysis and microbiological assessment without signs for a bacterial infection, high-dose steroid treatment and immunosuppressive treatment with cyclosporin A were initiated under the assumption of PG. Additionally, the patient was treated with hyperbaric oxygenation (HBO). The 2‑year follow-up showed a gradual restitution of the soft tissues.

Abstract
BACKGROUND Hyperbaric oxygen therapy (HBOT) has been widely used in the clinical setting. In this study, HBOT therapy was evaluated for its ability to ameliorate the epithelial-to-mesenchymal transition (EMT) phenomenon in keloid tissue. METHODS Keloid patients were randomly divided into two groups: keloid patients (K group, 9 patients) and keloid patients receiving HBOT (O group, 9 patients). A third group with normal skin (S group, 9 patients) was established for control. Before HBOT and surgery, a laser Doppler flowmeter was used to measure the keloid blood supply of patients in the O group. Hematoxylin and eosin (H&E) staining was used to observe morphology. E-cadherin, ZO-1, vimentin, fibronectin, vascular endothelial growth factor (VEGF), and hypoxia inducible factor (HIF)-1α were measured by immunofluorescence staining and Western blot analysis. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to evaluate the mRNA expression level of these factors as well. RESULTS In the O group, keloid blood perfusion was significantly reduced after patients received HBOT. Compared with the K group, lower expression levels of vimentin, vibronectin, VEGF, and HIF-1α were observed in the O group, whereas the expression of E-cadherin and ZO-1 was significantly higher. The mRNA expression of E-cadherin and ZO-1 was also increased after HBOT. CONCLUSIONS The expression levels of factors related to the EMT phenomenon were significantly reversed in keloid patients after they received HBOT, indicating that HBOT may be an effective therapy against the EMT phenomenon in keloid patients.

Abstract
OBJECTIVE Facial keloids commonly occur in young patients. Multiple keloid masses often converge into a large lesion on the face, representing a significant obstacle to keloid mass excision and reconstruction. We describe a new surgical method that excises the keloid mass and resurfaces the wound by saving the keloid skin as a skin flap during facial keloid treatment. METHODS Forty-five patients with facial keloids were treated in our department between January 2013 and January 2016. Multiple incisions were made along the facial esthetic line on the keloid mass. The keloid skin was dissected and elevated as a skin flap with one or two pedicles. The scar tissue in the keloid was then removed through the incision. The wound was covered with the preserved keloid skin flap and closed without tension. Radiotherapy and hyperbaric oxygen were applied after surgery. Patients underwent follow-up examinations 6 and 12 months after surgery. RESULTS Of the 45 total patients, 32 patients were cured and seven patients were partially cured. The efficacy rate was 88.9%, and 38 patients (84.4%) were satisfied with the esthetic result. CONCLUSION We describe an efficacious and esthetically satisfactory surgical method for managing facial keloids by preserving the keloid skin as a skin flap.

Abstract
Pyoderma gangrenosum (PG) is a rare neutrophilic inflammatory skin disease, characterized by recurrent skin ulcers, which in almost 50% of cases are associated with systemic autoimmune disorders, including rheumatoid arthritis, chronic hepatitis, inflammatory bowel disease, paraproteinemias and hematological malignancies. A systematic search of literature for PG was carried out using the PubMed, Embase, and Google Scholar databases for the purpose of this review and 2780 articles were retrieved up to February 2017. Inflammation represents the predominant aspect of the disease, but its pathophysiological mechanisms are not completely clear yet, since there are many studies showing only one or more isolated findings of the disease. The goal of PG treatment is to reduce inflammation in order to promote ulcer healing by minimizing side effects of therapy. Several systemic and local treatments are available, but the lack of large randomized double-blind studies results in an absence of a uniform therapeutic standard: thus, more clinical studies are required in order to make head-to-head comparisons between combination and single-drug therapies and to identify specific combination therapies for distinctive clinical patterns of PG.
