Pyoderma gangrenosum (PG) is an inflammatory condition characterized by chronic cutaneous ulcerations. There are three proposed PG diagnostic frameworks (Su, PARACELSUS, Delphi); however, they lack consensus, and their performance has not yet been validated in a well-defined cohort of patients with PG. In this cross-sectional retrospective cohort study, we sought ... Read more >>

<h4>Introduction</h4>Pyoderma gangrenosum (PG) is a rare, ulcerating neutrophilic dermatosis often associated with inflammatory bowel disease, rheumatoid arthritis, and myeloproliferative disorders. The classic description of PG includes irregularly shaped ulcers with undermined edges with a gun-metal gray or violaceous hue. The etiology remains unclear but appears to be related to genetically ... Read more >>

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, ... Read more >>

<h4>Background</h4>Pyoderma gangrenosum (PG) is a chronic, ulcerative neutrophilic dermatosis. PG presents a diagnostic challenge, largely due to the many mimicking diseases, the lack of confirmatory laboratory or biological markers, and the absence of widely accepted diagnostic criteria. In particular, PG is often mistaken for necrotizing soft tissue infections (NSTI).<h4>Methods</h4>We reviewed ... Read more >>

<b>Background:</b> Pyoderma gangrenosum (PG) is a neutrophilic disorder which classically presents as chronic, painful ulcers on the lower extremities. There is evidence supporting a potential role for intravenous immunoglobulin (IVIG) as adjuvant therapy for treatment-resistant cases; however, it is unclear which patients will most benefit from this modality of treatment ...

Pyoderma gangrenosum (PG) is a rare, ulcerative inflammatory skin disease that most commonly occurs in patients with inflammatory bowel disease, rheumatologic diseases, or hematologic diseases. Successful treatment of PG often requires immunosuppression and appropriate wound care. Systemic corticosteroids and cyclosporine are the first-line treatments for PG. However, chronic use of ...

<h4>Importance</h4>Pyoderma gangrenosum and necrotizing Sweet syndrome are diagnostically challenging variants of neutrophilic dermatosis that can clinically mimic the cutaneous and systemic features of necrotizing fasciitis. Improved characterization of these rare variants is needed, as improper diagnosis may lead to inappropriate or delayed treatment and the potential for morbidity.<h4>Objective</h4>To determine the ...

Reports detailing the acute formation of aluminum granulomas, which can cause persistent, intensely pruritic nodules secondary to the administration of aluminum-containing vaccines, are infrequently described in medical literature. To our knowledge, this is the first report describing the development of an aluminum granuloma causing a persistent, pruritic nodule at the ... Read more >>
