PSTPIP1 is a cytoskeletal adaptor and F-BAR protein that has been implicated in autoinflammatory disease, most notably in the PAPA syndrome: pyogenic sterile arthritis, pyoderma gangrenosum, and acne. However, the mechanism by which PSTPIP1 regulates the actin cytoskeleton and contributes to disease pathogenesis remains elusive. Here, we show that endogenous PSTPIP1 negatively regulates macroph...

Pyoderma gangrenosum (PG) is a challenging cutaneous manifestation associated with Dubowitz syndrome, rare genetic disorder characterized by multiple congenital anomalies, developmental delay, and distinctive facial features. This review article aims to provide comprehensive overview of the association between syndrome pyoderma gangrenosum, emphasizing clinical presentation, challenges in diagn...

We present the cases of 2 regular cocaine users aged 30 and 37 years who developed a cutaneous condition with an identical presentation and a similar clinical course. The lesions first appeared as eruptions on the back and then spread to other parts of the body. They consisted of painful inflammatory nodules that developed into abscesses and ulcers that grew outwards. They had a granulomatous b...

BACKGROUND Pyoderma Gangrenosum (PG) is a cutaneous condition, its diagnosis suggested by the presence of a painful cutaneous ulcer showing rapid progression. Pyoderma gangrenosum is associated with a concomitant systemic disease in 50 to 70 % of cases, including inflammatory bowel disease (IBD), rheumatoid arthritis, and lymphoproliferative disorders. Although PG has also been reported with vi...

Here, we report the unusual case of an ulcerative colitis female patient presenting together with cytomegalovirus infection, pyoderma gangrenosum and a noncaseating lung granuloma, both resistant to immunomodulatory drugs which dramatically obtained a clinical stable remission after restorative proctocolectomy.

Among the extraintestinal manifestations of inflammatory bowel disease (IBD), pyoderma gangrenosum (PG) often poses a therapeutic challenge. We describe two cases of PG associated with inflammatory bowel disease, who responded to treatment with Infliximab.
