ABSTRACT
BACKGROUND AND AIMS: Post-inflammatory polyps [PIPs] are considered as indicators of previous episodes of severe inflammation and mucosal ulceration. Inflammatory bowel disease [IBD], namely Crohn's disease [CD] and ulcerative colitis [UC], exhibit a perpetuating, relapsing and remitting pattern, and PIPs are a frequent sequela of chronicity. The aim of this study was to determine whether a high PIP burden is associated with a more severe disease course in patients with IBD. METHODS: This was a multinational, multicentre, retrospective study. IBD patients previously diagnosed with PIPs were retrieved from the endoscopic database of each centre. PIP burden was evaluated and associated with demographic and clinical data as well as factors indicating a more unfavourable disease course. RESULTS: A total of 504 IBD patients with PIPs were recruited [male: 61.9%]. The mean age at IBD diagnosis was 36.9 [±16.8] years. Most patients [74.8%] were diagnosed with UC. A high PIP burden was present in 53.4% of patients. On multivariable Cox regression analysis, a high PIP burden was independently associated with treatment escalation (hazard ratio [HR] 1.35, 95% confidence interval [CI] 1.04-1.75; pâ =â 0.024), hospitalization [HR 1.90; 95% CI 1.24-2.90; pâ =â 0.003], need for surgery [HR 2.28; 95% CI 1.17-4.44, pâ =â 0.02] and younger age at diagnosis [HR 0.99, 95% CI 0.98-0.99; pâ =â 0.003]. CONCLUSION: PIP burden was associated with a more severe outcome. Future prospective studies should focus on the characterization of PIP burden as to further risk stratify this patient cohort.

Superficial granulomatous pyoderma is a relatively rare variant of pyoderma gangrenosum, characterized by superficial ulceration with a vegetative margin and a clean granulating base. Ulcers in superficial granulomatous pyoderma are typically located on the trunk and may follow minor trauma. It may be misdiagnosed as classic pyoderma gangrenosum, despite having distinct characteristics. Here we report a case of superficial granulomatous pyoderma successfully treated with intravenous immunoglobulin (IVIg). LEARNING POINTS: Superficial granulomatous pyoderma is a rare variant of pyoderma gangrenosum.Histopathological and clinical characteristics of superficial granulomatous pyoderma are distinct from those of classic pyoderma gangrenosum.Superficial granulomatous pyoderma is often slow-growing and is only rarely linked to underlying systemic disease.IVIg may be an effective treatment option for superficial granulomatous pyoderma.
