PSTPIP1-associated myeloid-related proteinemia inflammatory (PAMI) syndrome: A case report and review of the literature.

PSTPIP1-associated myeloid-related proteinemia inflammatory (PAMI) syndrome is a rare autoinflammatory disorder often arising in pediatric patients. We present a case of an 18-year-old female with a past medical history of growth failure, immunoglobulin A nephropathy, and inflammatory arthritis who presented to a pediatric dermatology clinic with findings of acne, psoriasiform dermatitis, and hidradenitis suppurativa, whose clinical, genetic, and laboratory findings were most consistent with PAMI syndrome. We conducted a literature review to better characterize this rare condition in the context of dermatologic findings. Recognition of the distinctive skin findings seen in PAMI syndrome can help distinguish it from other inflammatory disorders, enabling expedited diagnosis and treatment.

Ulcerative erythematous papules and plaques on the face and lower legs of a man living with HIV: a clinicopathological challenge.

A 44-year-old male presented with a 2-month history of erythematous ulcerative papules and plaques on the scalp, face, and bilateral lower legs. He had a 5-year history of well-controlled HIV on antiretroviral therapy and recurrent syphilis infections. His face had violaceous plaques, while bilateral ankles and calves had ulcerative lesions with necrotic centers and purple borders. The morphologies clinically mimicked pyoderma gangrenosum on the lower extremities and cutaneous lymphoma on the face. Biopsy and reactive rapid plasma reagin confirmed a diagnosis of lues maligna, and the patient was successfully treated with penicillin G benzathine.

Disseminated Cutaneous Mucormycosis Developing in Peristomal Pyoderma Gangrenosum.

A patient on long-term glucocorticoid therapy for peristomal pyoderma gangrenosum (PPG) who developed mucormycosis (MM) of the wound with dissemination was presented. The importance of skin biopsy, together with clinical evaluation in patients with PPG who are resistant to conventional therapy or who develop new symptoms related to their PPG is stressed. The risk and pathogenesis of invasive fungal infections with long-term corticosteroid therapy were explored. The epidemiology and detection of mucormycosis is discussed in this article.

Episodic Presentations of Pustular Pyoderma Gangrenosum in PLHIV: A Case Report and Brief Review of Literature.

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.

Pyoderma gangrenosum, acne, and suppurative hidradenitis (PASH) syndrome: a single-institution case series with a focus on management.

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.

Postsurgical Pyoderma Gangrenosum After Penile Inversion Vaginoplasty: Case With Review of Diagnostic and Management Strategies.

Background: 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. Methods: 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. Results: 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. Conclusions: This unique case highlights the importance of prompt dermatological consultation, immunosuppression, and avoidance of further pathergy in the setting of suspicion for PSPG.

Novel Treatment of Pyoderma Gangrenosum With Porcine-Derived Extracellular Matrix Following Bilateral Latissimus Dorsi Breast Reconstruction: A Case Report.

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.

Adjunctive hyperbaric oxygen treatment for challenging pyoderma gangrenosum cases.

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.

The role of split-thickness skin grafting in the treatment of vasculitic and pyoderma gangrenosum ulcers in a multidisciplinary wound centre.

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.

Janus kinase inhibitors in the treatment of pyoderma gangrenosum: case report and review.

Pyoderma gangrenosum (PG) is a rare inflammatory dermatologic condition with neutrophilic infiltration of the skin that causes pustules and ulcerations. Janus kinase (JAK) inhibitors are immunomodulating agents that have been recently described in the literature as an effective treatment for PG. We describe a patient with PG on the lower extremities successfully treated with baricitinib. We also conducted a narrative review of the literature of PG patients treated with JAK inhibitors who were refractory to other treatments.

Monoclonal gammopathy in the setting of Pyoderma gangrenosum.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis characterized by ulcerative painful lesions with violaceous undermined borders. Up to 75% of PG cases develop in association with an underlying systemic disease. Monoclonal gammopathy is reportedly a concomitant condition with PG, with studies indicating immunoglobulin (Ig) A gammopathy as the most common. Whether gammopathy is associated with PG or is an incidental finding has been debated. We sought to investigate the association and characteristics of gammopathy in patients with PG. We retrospectively identified PG patients at our institution from 2010 to 2022 who were screened for plasma cell dyscrasia. Of 106 patients identified, 29 (27%) had a gammopathy; subtypes included IgA (41%), IgG (28%), and biclonal (IgA and IgG) (14%). Mean age was similar between those with and without gammopathy (60.7 vs. 55.9 years; P = .26). In addition, hematologic or solid organ cancer developed in significantly more patients with vs. without gammopathy (8/29 [28%] vs. 5/77 [6%]; P = .003). Among the subtypes of gammopathy, IgG monoclonal gammopathy had the highest proportion of patients with subsequent cancer development (4 of 8 patients, 50%). Study limitations include a retrospective, single-institution design with a limited number of patients. Overall, our data show a high prevalence of gammopathy in patients with PG; those patients additionally had an increased incidence of cancer, especially hematologic cancer.

Pyoderma Gangrenosum Presentation After Abdominoplasty and Augmentation Mastopexy.

Pyoderma gangrenosum is a rare ulcerative skin disease of uncertain etiology, which in some cases can be misdiagnosed as an infectious process. In even more unique cases, this can occur in the postoperative period. Termed postsurgical pyoderma gangrenosum, this type of inflammatory skin condition requires a high index of suspicion to be able to appropriately treat and reduce complications. We present a 55-year-old female who presented with multiple wounds following mastopexy and abdominoplasty. With a prompt diagnosis and a multidisciplinary approach, we could accurately care for the patient and minimize poor aesthetic sequela.

Pyoderma Gangrenosum: A Case Highlighting the Importance of Timely Diagnosis.

Pyoderma Gangrenosum (PG) is a distinctive dermatologic condition characterized by recurrent inflammatory ulcers, often manifesting with violaceous borders and undermined edges. We describe a 40-year-old male who presented with acute on chronic necrotic ulcer of the left index finger following foreign body penetration. Despite multiple emergency department visits and treatments for presumed recurrent cellulitis, including various debridements, his condition persisted without symptomatic relief. A high index of clinical suspicion, due to recurrent presentations and potential pathergy, prompted an excision biopsy which confirmed Pyoderma Gangrenosum (PG). Regrettably, due to delays in appropriate management, the patient chose amputation because of intolerable pain, highlighting the critical importance of timely diagnosis for optimal patient outcomes.

Analysis of clinical characteristics and factors affecting treatment responses in patients with pyoderma gangrenosum: a multicenter study of 239 patients☆.

BACKGROUND: Pyoderma Gangrenosum (PG) is a chronic disease characterized by recalcitrant skin ulcers. OBJECTIVE: We aimed to evaluate the demographic, clinical characteristics, treatments and factors affecting the treatment responses of patients with PG. METHODS: We performed a multicenter study of 12 tertiary care centers. We analyzed the data of the patients who were followed up with a diagnosis of PG between the years 2012‒2022 retrospectively. RESULTS: We included a total of 239 patients of whom 143 were female and 96 were male, with an average age of 54.2 ±â€¯17.4 years. The most common treatment was systemic steroids (n = 181, 75.7%). Among these patients, 50.8% (n = 92) used systemic steroids as the sole systemic agent, while 49.2% (n = 89) used at least one adjuvant immunosuppressive agent. The independent factors determined in regression analysis to influence response to systemic steroids positively were disease onset age ≥ 30-years, negative pathergy, absence of leukocytosis, negative wound culture, presence of a single lesion, and absence of upper extremity involvement. Biological agents were used in 18.4% (n = 44) of the patients in the present study. We also analyzed pathergy positive PG and early onset (onset age < 30) PG separately due to their distinct clinical features which were revealed during statistical analysis. STUDY LIMITATIONS: Retrospective nature of the present study. CONCLUSIONS: Analyses of the factors influencing treatment responses are addressed in this study. Also, we concluded that investigation for accompanying autoinflammatory diseases of pathergy positive PG and early onset PG is necessary and the patients in these two groups are more resistant to treatment, necessitating more complicated treatments.
