RESUMO
Vasculitic and pyoderma gangrenosum ulcers are traditionally treated with immunosuppressants, and the role of surgery in the treatment of these atypical ulcers remains unclear. This study aimed to investigate the need for surgical intervention as well as the outcome and safety of skin grafting in the treatment of 46 patients with vasculitic ulcers and 34 with pyoderma gangrenosum ulcers using data recorded in the validated Wound Registry. Of the 80 patients with atypical ulcers, 14% (n = 11) were treated surgically; these patients were older (p = 0.039), had lower mobility status (p = 0.002), and more often pulmonary diseases, rheumatoid arthritis, and previous arterial procedures (p = 0.007; p = 0.031; p = 0.031, respectively) than those treated conservatively. Of 181 ulcers, 15% (n = 27) were surgically treated, 78% once and 22% multiple times. During follow-up, 92.3% of both surgically and conservatively treated ulcers with available data healed. Of the surgically treated ulcers, median healing time after first surgical procedure was 96 days, and post-surgical complications were considered mild or unrelated to surgery. Our results suggest that if surgery is indicated, skin grafting is a safe and efficient treatment method provided that multidisciplinary approach is applied.

Peristomal pyoderma gangrenosum is an uncommon subtype of pyoderma gangrenosum mainly affecting stoma sites of patients with inflammatory bowel disease. While surgical treatments are often used to assist healing, little is known about the relationship between surgical interventions and the rate of recurrence of peristomal pyoderma gangrenosum. The aim of this study was to identify patient and clinical factors associated with peristomal pyoderma gangrenosum recurrence following surgical intervention. A multi-institutional retrospective case series and literature review was conducted to evaluate patient characteristics and perioperative treatment. Patients of any age with peristomal pyoderma gangrenosum undergoing surgical operations related to their pyoderma gangrenosum or due to another comorbidity were included. Descriptive statistics were used to characterize demographic information. Associations were evaluated using Wilcoxon's rank-sum test for continuous variables and Fisher's exact test for categorical data. Thirty-seven cases were included, 78.3% of which had a history of inflammatory bowel disease. Overall, 13 (35.1%) cases experienced recurrence at 30 days. There was no significant association identified between patient demographics, stoma location, surgical intervention, or perioperative treatment with rate of recurrence at 30 days post-operation. While no clinical risk factors or treatments were associated with recurrence, our work underscores the importance of a multidisciplinary approach to this disease to address gastrointestinal, dermatologic, and surgical components of treatment.

BACKGROUND: Wound debridement improves healing in a variety of acute and chronic ulcers. However, there is concern that debridement may trigger pathergy and worsen pyoderma gangrenosum (PG). OBJECTIVE: To determine whether published evidence supports conservative wound debridement for PG. DATA SOURCES: The authors reviewed the literature published in MEDLINE through January 2023 using the search germs "pyoderma gangrenosum" and "debridement." STUDY SELECTION: Articles reporting sharp surgical debridement or maggot debridement for PG were included in the review. The authors also searched the reference sections of the reviewed articles for additional reports on debridement for PG. DATA EXTRACTION: Clinical data regarding patient status, procedures performed, and patient outcomes were extracted from the selected articles. DATA SYNTHESIS: There are multiple reports of uncontrolled, active-phase PG wounds worsening after aggressive excisional debridement of viable inflamed tissues. In contrast, there is no evidence indicating that conservative debridement of nonviable necrotic tissue worsens PG wounds, regardless of the disease activity. There are multiple reports of successful debridement and surgical grafting for PG in remission. CONCLUSIONS: There is no evidence in favor of or against using conservative debridement of nonviable necrotic tissue for a PG wound. Therefore, it should not be considered contraindicated, even in the active phase of the disease.

CASE: A 61-year-old woman with lower back and radicular leg pain underwent minimally invasive spinal fusion at L5-S1. By postoperative day 6, she exhibited erythema, wound dehiscence, and necrotic changes. Although a necrotizing infection was initially suspected, multiple debridements and antibiotic therapy failed to improve her condition. The patient was eventually diagnosed with pyoderma gangrenosum (PG) and was managed with immunosuppressants and extended wound care. CONCLUSION: PG is a rare dermatosis that is often misdiagnosed, leading to inappropriate treatment, debridements, and additional complications. Prompt identification and multidisciplinary collaboration are key to preventing unnecessary interventions and achieving the best outcomes.

BACKGROUND: Pyoderma gangrenosum (PG) is a reactive, noninfectious, neutrophilic dermatosis. Diagnosis of PG is based on exclusion, due to lack of availability of a confirmatory test. PG is not caused by infection or gangrene. Misdiagnosis or delayed diagnosis of PG can lead to devastating results. CASE PRESENTATION: In this report, we present a patient with a delayed diagnosis of PG lesion on right hand. Despite initial surgical treatment, the wound was aggravated, and amputation was considered; however, it was eventually treated successfully with an autologous split thickness skin graft. CONCLUSIONS: Knowledge of the PG is essential to actively consider PG in early stage to help facilitate immediate treatment and avoid unnecessary interventions that may worsen the outcome.

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.

INTRODUCTION: Pyoderma gangrenosum (PG) is an uncommon inflammatory skin disease that is characterized clinically by the development of painful pustules that subsequently progress to large cutaneous ulcers. There is no universally effective treatment for PG, and a combination of local and systemic therapies is often used to manage it. Biologically active, cryopreserved human skin allograft (BSA) has become a standard part of the treatment algorithm for complex nonhealing wounds. These allografts facilitate the wound healing cascade by delivering the essential biologically active compounds of fresh skin to the wound bed and promoting wound bed revascularization. OBJECTIVE: The purpose of this case series was to illustrate how the use of human split-thickness allografts positively contributes to wound healing in patients with PG. CASE PRESENTATIONS: Five cases highlighting the efficacy of a BSA in achieving clinical wound healing in patients with complex PG ulcerations are presented. Clinical findings appear to indicate that the positive effect of BSA in combination with systemic therapies on wound beds in patients with PG is because of a combination of both the unique alterations in the patient's immune system in addition to the possible delays in clearance of cellular components of the allograft, which promote the strong inosculation and revascularization necessary for wound healing. CONCLUSIONS: The BSA studied herein appears to aid in wound healing because it has natural components found in human skin that facilitate wound healing, and it eliminates the potential for pathergy because no graft harvesting from the host is performed. These allografts can be applied numerous times, and each has the major essential components of human skin wound healing for a more rapid and complete epithelialization.

INTRODUCTION: Pyoderma gangrenosum (PG) is a relatively uncommon necrotizing and ulcerative cutaneous disorder. It is often associated with a systemic inflammatory disease but may also present following trauma to the skin due to pathergy. Given its rare occurrence and nonspecific histology, PG is primarily a diagnosis of exclusion, which often results in delayed treatment. Very few cases of PG following autologous breast reconstruction have been reported in the literature, particularly in the absence of systemic disease. CASE REPORT: Presented is the case of a 62-year-old female with a history of ductal carcinoma in situ who underwent a left breast mastectomy with immediate deep inferior epigastric perforator flap breast reconstruction complicated by fever and leukocytosis as well as erythema, edema, and bullae involving the mastectomy flaps. Initially, necrotizing soft-tissue infection was suspected, and 2 debridements were performed. A diagnosis of PG was made on postoperative day 7, and the patient responded favorably to high-dose prednisone. Reconstruction was performed with a bilayer wound matrix and delayed skin grafting. Despite significant loss of mastectomy skin flap, the free flap was preserved. CONCLUSIONS: Although PG is a rare complication, it should be considered in the differential diagnosis for patients with atypical presentation of infection following breast reconstruction, even in the absence of systemic inflammatory disease. Early diagnosis and multidisciplinary management may prevent unnecessary surgical intervention and enable flap preservation. Furthermore, bilayer wound matrix placement may be useful as an intermediate reconstruction to determine if it is safe to proceed with skin grafting to avoid further pathergy. The findings in this case suggest that final reconstruction may be safely performed sooner than noted in the literature.

We herein report a case of penile pyoderma gangrenosum that was successfully treated with prednisolone and by urethrocutaneostomy without penectomy. A man in his 50s visite dour department because of painful urination. Pyuria and redness of the external urethral meatus were present. Treatment for urethritis with antibiotics did not improve his symptoms, and a painful ulcer and fistula formation between the glans and urethra subsequently developed. Microbiological cultures revealed no growth, and punch biopsy showed only nonspecific inflammation, leading to a diagnosis of penile pyoderma gangrenosum. We initiated prednisolone (PSL) at 40 mg once daily following placement of an indwelling suprapubic cystostomy tube for dysuria. However, the treatment was ineffective. Therefore, the dosage of PSL was increased to 65 mg once daily. The ulcer disappearedï¼ but urethral stricture remained. Six hundred days after PSL treatment, we performed urethrocutaneostomy. The patient became free of the cystostomy and was able to urinate spontaneously. In recent years, there has been an increasing number of reports of penile preservation in the treatment of penile pyoderma gangrenosum, but knowledge regarding which patients require urethral surgery is lacking. Urologists should keep in mind increased susceptibility to infection, pathergy and possible recurrence, when considering urethral surgery for penile pyoderma gangrenosum.

Pyoderma gangrenosum is a diagnosis of exclusion. It occurs rarely and is frequently misdiagnosed. It can result in severe tissue loss, particularly in surgical units with little experience. Nevertheless, surgical treatment might be necessary for reconstruction, once the progression of these wounds is controlled. We aimed to characterize medical findings in Pyoderma patients with extensive defects to assess the surgical procedures and their outcome. A retrospective study was conducted at our centre over an 18-year period. Inclusion criteria were the diagnosis of Pyoderma gangrenosum and at least one surgical intervention. Descriptive statistics were used to analyse the data. Sixteen patients were included. The mean size of the lesions was noted with 12 × 8 cm. Surgical procedures comprised debridements/necrectomies, allograft conditioning, negative pressure wound therapy, skin grafts, and microvascular free flaps. Seven patients were discharged with healed wounds, six with minor wound healing disturbances. Three patients succumbed to their underlying diseases. Drug-based therapy can stop the progress of Pyoderma, but severe tissue loss can be a persistent problem. According to our data, reconstructive-surgical treatments (debridement, autologous and allogenous skin transplantation and microvascular free flaps) act as an integral component of the therapy and can be safe options for selected patients. Furthermore, we provide an algorithm that we follow at our department in severe cases.

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.

CASE: We present a case of a 60-year-old polytraumatized man who developed postoperative pyoderma gangrenosum (PG) after his initial stabilization procedures, mimicking a postoperative infection. This caused a delay in diagnosis, leading to progression of his wounds and a delay in initiation of the appropriate treatment. Once his PG was appropriately treated, his clinical status and wounds improved. He underwent successful wound coverage by plastic surgery and has been recovering from his injuries. CONCLUSION: Prompt identification and initiation of treatment for postoperative PG is critical to avoid exacerbation of wounds and subsequent morbidity to the patient.

INTRODUCTION: Pyoderma gangrenosum (PG) is a rare skin disease that often presents as a uniquely painful and necrotic ulceration of the lower extremity. Pyoderma gangrenosum is often misdiagnosed and can have deleterious consequences to the patient, as there is no gold standard treatment and it can be difficult to manage. Surgery for these wounds is controversial, as pathergy can develop, worsening the ulceration. Advanced wound care products such as cellular- and/or tissue-based products (CTPs) are effective in helping stagnant chronic wounds reach full closure. Amnion/chorion-based skin substitutes that have been cryopreserved and contain viable cells have been shown to promote more cell recruitment and reduce inflammation. OBJECTIVE: This case series presents evidence of using a cryopreserved umbilical cord tissue with living cells in adjunctive treatment of wounds associated with PG. MATERIALS AND METHODS: This report presents 3 different clinical scenarios of lower extremity PG treated surgically with viable cryopreserved umbilical tissue (vCUT). RESULTS: All 3 patients were successfully treated with vCUT and resulted in complete healing. CONCLUSIONS: To the best of the authors' knowledge, this is the first case series demonstrating the ability of vCUT to heal these difficult-to-treat ulcers. In addition, it may be an effective modality to adjunctive management of PG.

Pyoderma gangrenosum (PG) classically presents with an acute inflammatory stage, characterized by rapid evolution of painful ulcerations. The pathergy associated with PG lesions complicates disease management. Although PG is commonly treated with immunosuppression, some patients have refractory noninflammatory ulcers. In this subpopulation, there are case reports of successful surgical treatment. However, there is no consensus on optimal perioperative treatment for patients with PG undergoing surgery of any kind, PG related or otherwise. Therefore, we conducted a comprehensive literature review describing perioperative management practices and risk factors that may predict response to surgical intervention. We identified 126 cases of surgical intervention in patients with active PG; among these, only 16.7% experienced postoperative disease progression. No perioperative treatments or clinical risk factors were identified as statistically significant predictors of disease recurrence. Although limited by case series design and publication bias, this study is a valuable means of hypothesis generation for this rare condition.

BACKGROUND: Pyoderma gangrenosum is a rare ulcerating skin disease of unknown etiology, making its coincidence with orthopedic trauma a rare challenge. Patients are at risk of progression of the existing lesions and development of new lesions upon skin injury when surgical procedures are performed. To our knowledge, this is the first report in the literature of disease unrelated surgery during active pyoderma gangrenosum. CASE PRESENTATION: We present a case of femoral neck fracture in a Caucasian patient with concurrent pyoderma gangrenosum localized in the axilla. Hemiarthroplasty was safely performed after disease activity was reduced with systemic corticosteroids. Tissue-protective wound closure was used together with perioperative corticosteroids and antibiotics. No signs of pyoderma gangrenosum developed at the surgical wound site, and the axillary lesions showed constant improvement until healing with scar tissue. CONCLUSIONS: In our patient, the preoperative steroid treatment, perioperative antibiotics, and soft tissue protective surgical technique led to successful management of this rare coincidence.
