Abstract:ImportancePyoderma gangrenosum (PG) is a rare neutrophilic dermatosis. Few studies have evaluated the mortality outcomes of patients with PG.ObjectiveTo investigate all-cause and cause-specific mortality in patients with PG.Design, Setting, and ParticipantsThis retrospective population-based cohort study used data from the National Health Insurance Service database of Korea and the National Death Registry of Korea from patients with incident PG (≥3 documented visits with an International Statistical Classifica… Show more
“…The addition of negative pressure wound therapy, such as VAC dressing, can help accelerate wound closure and healing [ 15 ]. PG has been associated with a higher mortality risk when compared to the general population, and the prognosis can be improved with a multidisciplinary approach [ 16 ]. Although our patient lost follow-up and did not undertake treatment at our center, wound coverage could have been subsequently achieved using a skin graft and a muscle flap if required, with excellent outcomes over subsequent follow-ups [ 4 - 12 ].…”
Introduction: Pyoderma gangrenosum (PG) following a primary total knee arthroplasty (TKA) surgery is extremely rare, with very few cases reported in the literature. Case Report: We report our clinical experience of a 65-year-old female who developed PG following a primary TKA surgery. Corticosteroids and local wound care with vacuum-assisted closure dressing helped achieve rapid improvement in the wound condition. Conclusion: Post-surgical PG in TKA can be challenging with limited evidence for its definitive treatment. A high degree of suspicion and a multidisciplinary management approach will help in the timely diagnosis and optimization of treatment for this condition. Keywords: Wound breakdown, pyoderma gangrenosum, knee, total knee arthroplasty.

“…While the causes of this increase remain unclear, the mortality risk for PG patients is estimated to be three times higher than the general population [1]. A recent population-based cohort study by Lee et al [2] supported that PG patients have an elevated all-cause mortality risk. PG patients included in this study were shown to have a higher mortality risk from a multitude of conditions including infection, hematological disorders, neoplasm, and respiratory disease as compared to controls.…”
Introduction: Pyoderma gangrenosum (PG) is a rare ulcerative skin condition with an increased risk of mortality compared to the general population. The causes of this increased risk are not well understood. Misdiagnosis is common in pyoderma gangrenosum, and many studies are limited by the inclusion of misdiagnosed cases. The goal of this study is to review autopsy findings, identify causes of death, and identify factors that may worsen outcomes among deceased patients confirmed to have PG.
Methods: Data was retrospectively reviewed from the electronic medical records at five academic hospitals. A search was conducted for deceased patients with a diagnosis of PG who had autopsy performed between 2010 and 2020. We report a descriptive analysis of eleven patients and their clinical characteristics, causes of death, and autopsy findings.
Results: The average age of death was 62.9 years. Seven patients had at least one underlying condition known to be associated with PG including inflammatory bowel disease, inflammatory arthritis, or a hematologic disorder. The most common cause of death was infection (n = 6, 54.5%) followed by pulmonary embolism (n = 3, 27.3%) and myelodysplastic syndrome (n = 2, 18.2%). Six patients (54.5%) were taking systemic steroids at the time of death.
Conclusion: The development of PG may shorten life expectancy among those with underlying conditions associated with PG, and common treatments for PG may contribute to the risk of fatal complications. Awareness of the risk of infection, thrombosis, and malignancy among those with PG is necessary for proper management. Further research is needed to explore the relationship between pyoderma gangrenosum and thromboembolism.
