title: Pyoderma gangrenosum: associations revisited.
abstract: Fourteen cases of pyoderma gangrenosum were seen over a period of 24 years at the Hull Royal Infirmary Dermatology Department. Several associated conditions were found. Seven cases were associated with rheumatoid arthritis of which five were sero-positive, including one with Felty's syndrome. One case was associated with both ulcerative colitis and psoriasis; one with polycythemia rubra vera; two patients had diverticular disease including one who also had rheumatoid arthritis; one had positive syphilis serology. In three cases there was no significant associated disease identified. Ten out of the fourteen cases were women, indicating a female preponderance by a ratio of about 2F:1M; a figure similar to that stated by Seitzinger. The age of presentation ranged from 30 to 80 years.
