Postsurgical Pyoderma Gangrenosum After Minimally Invasive Transforaminal Lumbar Interbody Fusion: A Case Report.

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.

Pioderma gangrenoso após mamoplastia redutora: desafios diagnóstico e terapêutico / Pyoderma gangrenosum after reduction mammoplasty: diagnostic and therapeutic challenges

O pioderma gangrenoso (PG) é doença inflamatória da pele, que pode se desenvolver espontaneamente, associado a certas doenças sistêmicas e neoplásicas, ou ao trauma cirúrgico, incluindo os das mamas. Há relatos cada vez mais frequentes, considerando o aumento desse procedimento nos dias atuais. A manifestação clínica das úlceras é característica e deve ser lembrada nas evoluções cicatriciais desfavoráveis com intensa reação inflamatória, perdas teciduais, secreção sanguinolenta e/ ou purulenta, fundo granuloso e bordas elevadas. Relatase o caso de paciente que teve pioderma gangrenoso após mamoplastia redutora. Respondeu ao corticosteroide sistêmico, e vem evoluindo sem recidivas até o momento.

Pyoderma gangrenosum (PG) is an inflammatory disease of the skin that may develop spontaneously. It is associated with certain systemic and neoplastic diseases, including those of the breasts. PG is also associated with surgical trauma. It has been increasingly reported, along with the increase in the incidence of reduction mammoplasty procedures. The clinical manifestation of ulcers is characteristic of PG and it should be considered in cases of poor healing with intense inflammatory reaction, tissue loss, bloody and/ or purulent secretion, granular background, and lesions with high edges. We describe a patient who developed PG after reduction mammoplasty. She has since responded to systemic corticosteroids and has had no relapse to date.

Pioderma gangrenoso em pós-operatório de mamoplastia redutora: relato de caso / Pyoderma gangrenosum following reduction mammoplasty: a case report

O pioderma gangrenoso (PG) é uma dermatose neutrofílica inflamatória, de etiologia desconhecida. O PG é idiopático em 25-50% dos casos. Em aproximadamente 50% dos casos tem sido descrita a associação com doenças sistêmicas, tais como: doença de Crohn, gamopatias monoclonais, artrites soropositivas, colagenoses, doença de Behcet, granulomatose de Wegener, doenças mieloproliferativas e infecciosas, principalmente hepatites e Aids. Clinicamente, apresenta quatro variantes: ulcerada, bolhosa, vegetante e pustulosa. A forma mais frequente é a ulcerativa, que se inicia com pápula ou nódulo e evolui rapidamente para lesões ulceradas e dolorosas. Em até 25% dos casos de PG, o surgimento de novas lesões pode ser desencadeado por traumas, tais como picadas de insetos, injeções intravenosas e biópsia - fenômeno conhecido por patergia. Nesse trabalho, é apresentado um caso de PG extenso das mamas em pós-operatório de mamoplastia redutora, de difícil diagnóstico; iniciado na evolução pós-operatória em outro serviço. Devido à quebra da relação médico-paciente, vem procurar nosso serviço. Apresentou ótima resposta ao tratamento com corticoterapia (corticoterapia intra e perilesionais com triancinolona) no ato do desbridamento, e introdução de corticoterapia via oral (prednisona) em esquema escalonado de desmame.

Pyoderma gangrenosum (PG) is an inflammatory neutrophilic dermatosis of unknown etiology and is idiopathic in 25%- 50% cases. In approximately 50% of PG cases, an association with systemic diseases, such as Crohn's disease, monoclonal gammopathies, seropositive arthritis, collagenosis, Behcet's disease, Wegener's granulomatosis, and myeloproliferative and infectious diseases (mainly hepatitis and AIDS), has been described. Clinically, PG presents four variants: ulcerated, bullous, vegetative, and pustular. The most frequent form is ulcerative, which begins as a papule or nodule and evolves rapidly into ulcerated and painful lesions. In approximately 25% of PG cases, the onset of new lesions can be triggered by traumas such as insect bites, intravenous injections, and biopsy, a phenomenon known as pathergy. Here, we present a case of extensive PG of the breasts following reductive mammoplasty surgery. It was a difficult case to diagnose and was initiated in the postoperative period of another service. Due to the breakdown of the doctor-patient relationship, the patient approached us for assistance. The patient showed an excellent response to corticotherapy (intra and perilesional corticotherapy with triamcinolone) during debridement and oral steroid (prednisone) therapy in the weaning phase.

Pioderma gangrenoso: um desafio para o cirurgião plástico / Pyoderma gangrenosum: a challenge for the plastic surgeon

Introdução: O pioderma gangrenoso (PG) corresponde a uma dermatose autoimune crônica e rara. Sua base etiológica ainda permanece pouco conhecida, sendo idiopático em 25 a 50% dos casos, nos demais está associado com doenças sistêmicas de fundo autoimune, tem uma incidência de 2 a 3 casos em 1 milhão de habitantes por ano. No Brasil, este índice é de 0,38 casos por 10.000 atendimentos, as mais acometidas são as mulheres entre a segunda e quinta década de vida. O quadro clínico é variável, sendo que a forma ulcerosa, que surge sobre uma cicatriz prévia, é a mais prevalente. Relato de Caso: Paciente do sexo feminino, 39 anos de idade, previamente hígida, foi submetida à mamoplastia redutora, evoluiu com úlcera necrótica em cicatriz vertical de mama esquerda. Realizado desbridamento de tecidos desvitalizados, prescrita antibioticoterapia, apresentando piora importante da lesão, sendo considerada a hipótese de PG. Iniciado tratamento com corticoterapia oral e tópica com remissão do quadro. Conclusões: O PG representa um desafio no diagnóstico e, geralmente, demonstra a dificuldade diagnóstica, podendo ser confundido com infecção do sítio cirúrgico.

Introduction: Pyoderma gangrenosum (PG) is a chronic and rare autoimmune dermatosis. Its etiology remains poorly understood, being idiopathic in 25 to 50% of cases; in others, it is associated with systemic diseases with autoimmune background and has an incidence of 2 to 3 cases per 1 million per year. In Brazil, the rate is 0.38 cases per 10,000 clinical visits, and women between the second and fifth decades of life are the most affected. The clinical presentation is variable, and the ulcerous form, which appears on a previous scar, is the most prevalent. Case Report: A 39-year-old, previously healthy female underwent reduction mammoplasty, and later developed a necrotic ulcer on a vertical left breast scar. Debridement of devitalized tissue was performed, with significant worsening despite antibiotic therapy. The appearance suggested PG. Treatment with oral and topical corticosteroids was then initiated with remission. Conclusions: PG represents a diagnostic challenge, and can be confused with surgical site infection.

Application of Viable Cryopreserved Human Placental Membrane Grafts in the Treatment of Wounds of Diverse Etiologies: A Case Series.

There is evidence in the literature that viable cryopreserved human placental membrane (vCHPM) grafts are effective in treating diabetic foot ulcers and venous leg ulcers. OBJECTIVE: This case series presents 3 cases of chronic ulcerations - 1 arterial ulcer (AU), 1 pressure ulcer (PU), and 1 recurrence of a pyoderma gangrenosum ulcer (PGU) - that had failed previous courses of standard wound care and were subsequently treated with vCHPM to determine if the treatment is an effective modality for treating wounds of these etiologies. MATERIALS AND METHODS: This retrospective review describes 3 cases in which patients with chronic wounds that had failed standard of care treatments for more than 4 weeks were subsequently treated with weekly applications of vCHPM. Each wound area was recorded and photographed on a weekly basis and wound area reduction also was charted weekly. RESULTS: The PU and AU both reached full closure in 4 and 5 weeks, respectively, without complication. The patient with the PGU achieved 64% closure after 9 applications of vCHPM. CONCLUSIONS: Viable CHPM is an effective treatment modality for wounds of diverse etiologies and shows better results than have been previously published with standard of care. In patients with PGUs, medical optimization and close management of comorbidities is essential in achieving optimal results.

Pyoderma gangrenosum: Classic and emerging therapies. / Pioderma gangrenoso: terapias clásicas y emergentes.

Pyoderma gangrenosum is an ulceronecrotising dermatosis that represents a challenge for any clinician, not only for its ability to mimic other dermatoses but also for its lack of response to treatment. During the past year, there have been new studies about the efficacy of standard therapies, such as cyclosporine and systemic corticosteroids. These studies showed that classic treatment was comparable, but they are insufficient as monotherapy. That being said, new emerging therapies are becoming important, as the use of corticosteroid-sparing agents, tumour necrosis factor inhibitors or even surgery. This review updates the current evidence for the treatment of pyoderma gangrenosum.

Pioderma gangrenoso em abdominoplastia: relato de caso / Pyoderma gangrenosum in abdominoplasty: a case report

Pioderma gangrenoso é uma doença caracterizada por úlceras dolorosas, com bordos imprecisos, de diversos tamanhos e profundidade. O diagnóstico é eminentemente clínico, sendo muitas vezes de exclusão. O tratamento não é específico. O desbridamento cirúrgico não é indicado devido a seu potencial de patergia. Neste trabalho, relatamos um caso de pioderma gangrenoso em uma paciente submetida à abdominoplastia.

Pyoderma gangrenosum is a disease characterized by painful ulcers, with imprecise borders of various sizes and depth. The diagnosis is essentially clinical and often exclusionary. The treatment is not specific. Surgical debridement is not indicated because of its potential pathergy. We report a case of pyoderma gangrenosum in a patient who underwent abdominoplasty.

Pioderma gangrenoso pós-mamoplastia redutora: relato de caso e discursão / Pyoderma gangrenosum after reduction mammaplasty: case report and discussion

We report the case of a 31-year-old woman who underwent mammoplasty and abdominoplasty and developed a rare and recurrent skin disease, of unknown etiology that was diagnosed as pyoderma gangrenosum. While the diagnosis was clinical, the treatment was empirical. An association between this disease and other systemic diseases was observed, in addition to pathergy (development of a new inflammatory lesion in are as of trauma) and changes in cellular immunity. The patient was empirically treated with antibiotics, sulfone, corticosteroids, and topical agents and experienced complete wound healing with no recurrence.

Neste artigo relata-se o caso de uma jovem de 31 anos de idade, submetida a mamoplastia e abdominoplastia, que evoluiu com uma doença cutânea rara, recorrente e de causa desconhecida: pioderma gangrenoso. O diagnóstico é clínico e o tratamento permanece empírico. Tem-se encontrado relação entre essa afecção e outras doenças sistêmicas, além de evidências do fenômeno de patergia (desenvolvimento de uma nova lesão inflamatóriana área do trauma) e de alterações da imunidade celular. A paciente foi tratada empiricamente com antibióticos, sulfona e corticoide, e com tratamento tópico, evoluindo para o fechamento completo das lesões sem apresentar recorrência.

Synchronous pyoderma gangrenosum and inflammatory bowel disease, healing after total proctocolectomy.

We present a female patient observed with painful violaceous plaques with central bullae and pustules on the lower limbs, rapidly transformed into ulcers, associated with bloody diarrhea, recurrent oral erosions and hyperthermia in the previous 3 months. Cutaneous biopsy was consistent with pyoderma gangrenosum, and intestinal diagnostic procedures revealed a non-classifiable inflammatory bowel disease with high x-ANCA titers. Soon after admission the patient was submitted to total proctocolectomy following colonic perforation. Complete ulcer healing occurred three months after surgery, without recurrence. Pyoderma gangrenosum is a rare dermatosis frequently associated with inflammatory bowel disease. This case is particularly interesting for the synchronic clinical presentation of cutaneous and intestinal diseases, but also for the prompt regression of the former after total proctocolectomy.

Apresentamos uma paciente do sexo feminino observada com múltiplas placas violáceas dolorosas dos membros inferiores, com bolhas e pústulas evoluindo rapidamente para lesões ulceradas, surgindo no contexto de diarreia sanguinolenta, erosões orais recorrentes e febre com três meses de evolução. A biópsia cutânea foi compatível com pioderma gangrenoso; o estudo complementar revelou doença inflamatória intestinal inclassificável com títulos elevados de x-ANCA. Após perfuração cólica, a doente foi submetida a proctocolectomia total, com rápida cicatrização das lesões cutâneas ulceradas em três meses, sem recorrência. O pioderma gangrenoso é uma dermatose rara frequentemente associada a doença inflamatória intestinal. É interessante verificar neste caso a apresentação clínica sincrónica das doenças cutânea e intestinal, bem como a rápida resolução da primeira após proctocolectomia total.

Pioderma gangrenoso vegetante asociado con insuficiencia renal / Pioderma gangrenous vegetante associated with renal inadequacy

Se presentó el caso de un paciente que desarrolló un pioderma gangrenoso vegetante que concomitaba con una insuficiencia renal aguda, esto lo llevó a un estado de gravedad extrema. El paciente recibió tratamiento inicialmente con antibióticos sistémicos por considerarse el cuadro como una piodermitis, pero no se obtuvo una respuesta satisfactoria. Después fue tratado con Levamizol y alfa interferón, y se logró con este tratamiento mejoría de su estado general y de sus lesiones cutáneas. Se realizó entonces exéresis quirúrgica, con autoinjerto de las lesiones de la cara y el pene, con buenos resultados. Las lesiones pioderma gangrenoso fueron recidivantes, se trataron con prednisona y se obtuvo una rápida resolución de las lesiones en cada ocasión que se presentaron(AU)
