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.

BACKGROUND: Pyoderma gangrenosum, acne, and suppurative hidradenitis (PASH) syndrome is a rare condition characterized by clinical features of all three dermatologic conditions. The management of PASH syndrome is difficult, with no consensus on treatment guidelines. Since PASH syndrome can increase morbidity and adversely impact quality of life, better characterization of effective therapies is needed.
METHODS: A retrospective cohort study was conducted to identify all patients with pyoderma gangrenosum (PG) treated at The Ohio State University Wexner Medical Center between 2015 and 2021. PG diagnosis was confirmed via PARACELSUS score. Subsequent chart review identified eight patients with concomitant hidradenitis suppurativa (HS) and acne who were clinically diagnosed with PASH syndrome.
RESULTS: Eight patients were clinically diagnosed with PASH syndrome based on their clinical presentation at our institution. Seven patients had failed some type of medical therapy prior to presentation, including topical corticosteroids, oral corticosteroids, oral antibiotics, and biologics. One patient had also tried surgical drainage at an outside institution. Six patients were effectively treated with biologics, usually in combination with other therapies. One patient experienced improvement of her skin lesions after diagnosis and treatment of her underlying hematologic malignancy.
CONCLUSIONS: Medical management with biologics in combination with corticosteroids and/or antibiotics was effective in the management of most patients. Diagnosis and treatment of an underlying condition should be prioritized in refractory cases. If workup is negative, surgical management may be considered. Further investigation with a greater number of patients is required to develop management guidelines for PASH syndrome.

Pyoderma gangrenosum (PG) is a sterile inflammatory skin condition that is frequently associated with immune-related diseases, including inflammatory bowel disease (IBD). PG causes noninfectious ulcers. Facial PG is uncommon while PG usually occurs on the trunk and lower limbs. Herein, we report a case of a male teenager with fever, pustules, ulcers, and necrosis on both cheeks. He was initially diagnosed with complicated acne with bacterial infection, but the condition progressed to subcutaneous ulcers despite treatment. Biopsy revealed inflammatory lesions in dermal and subcutaneous tissue with neutrophil infiltration, consistent with PG. Although lacking typical IBD symptoms, blood tests revealed anemia and positive fecal occult blood. Sigmoidoscopy revealed inflammation, ulcers, and pseudopolyps in the colon and rectum, thereby diagnosing ulcerative colitis (UC). After treating PG and UC with prednisolone and skin grafts, golimumab was prescribed. The patient is now in remission. Necrotic tissue buildup can complicate closure in PG cases;this emphasizes the need for effective IBD treatment to facilitate procedures such as skin grafts.

BACKGROUND: 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.
METHODS: 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.
CONCLUSIONS: HBOT should be more readily considered as a treatment option for those with PG.

Pyoderma gangrenosum (PG) is a rare disease characterized by ulcerative cutaneous lesions that can occur postoperatively and is often associated with autoimmune disorders. PG is diagnosed by excluding other conditions that can cause ulcerations, such as infections, which may also result in immunosuppressive treatment delays and suboptimal wound care. Operative debridement of wounds has traditionally been avoided in the acute setting secondary to pathergy. This article presents a case of extensive breast PG that was successfully treated with surgical debridement, porcine-derived extracellular matrix, and negative pressure wound therapy while on systemic immunosuppressive therapy.

UNASSIGNED: Postsurgical pyoderma gangrenosum (PSPG) is a highly uncommon and unpredictable wound healing complication. Rapid progression of ulcers at incisions can cause unfettered dehiscence. Most commonly, PSPG involves breast procedures; however, in this work, we detail a case of a patient who developed PSPG 10 days postoperatively after penile inversion vaginoplasty.
UNASSIGNED: The patient in this case underwent a penile inversion vaginoplasty with orchiectomy in the standard fashion. She had no risk factors for PSPG. Following an uncomplicated hospital stay, the patient developed difficulty with pain control and increasing serous drainage on the 10th postoperative day. On readmission, the patient was found to have developed large, mildly purulent ulcers throughout the perineal wound edges. On exam under anesthesia, the neovaginal canal was found to be patent and intact. The dehisced portions of the incisions were left open and redressed with occlusive bismuth-petrolatum dressing. Dermatology was promptly consulted with suspicion for PSPG. The patient was started on an 18-day prednisone taper with cyclosporine, along with doxycycline and ciprofloxacin.
UNASSIGNED: After 5 days of immunosuppressive treatment, the ulcers visibly converted to healthy granulation tissue and were no longer actively purulent. Following another washout, the dehisced wound edges were reapproximated. At follow-up, the patient had no evidence of PSPG recurrence and continued dilating on schedule. Our patient recovered from PSPG without further complications and a satisfactory aesthetic result.
UNASSIGNED: This unique case highlights the importance of prompt dermatological consultation, immunosuppression, and avoidance of further pathergy in the setting of suspicion for PSPG.

We report a case of a 54-year-old female diagnosed with HIV and antiretroviral therapy (ART) for the same. Seven years ago, she suffered from fever, cough and weight loss, was diagnosed with pulmonary tuberculosis and also seropositive for HIV. She suffered from Herpes Zoster infection, after which her ART regimen was changed to TLD (tenofovir, lamivudine and dolutegravir). The patient presented with two episodes of pyoderma gangrenosum (PG), which were biopsy-proven, corresponding to a rise in CD4 counts above 500. She responded to glucocorticoids, both systemic and topical.
