About pyoderma gangraenosum (PG)

Ulcerative PG is a rare, non-infectious, neutrophilic dermatosis recurrent skin disorder characterized by painful, necrolytic, cutaneous ulcers that can rapidly progress. An estimated up to 50,000 patients in the US and Europe are affected. PG is considered an autoimmune disease of the skin, but the underlying cause of PG is not known in detail. PG lesions are histologically characterized by pronounced infiltration of neutrophils, and activated neutrophils surrounding the ulcers are believed to be disease drivers. PG typically occurs in patients between the ages of 40 and 60, and PG patients often also suffer from other autoimmune disorders, such as inflammatory bowel disease and rheumatoid arthritis. There are currently no approved drugs for the treatment of PG in the U.S. or in Europe, and there is no established standard of care based on controlled studies.
