Inflammatory Bowel Disease (IBD), including Crohn’s disease (CD), ulcerative colitis (UC), and indeterminate colitis (IC), affects 77/100,000 children in the US. It is estimated that 2-5% of children with UC and 1-10% of children with CD experience a cutaneous manifestation of IBD. The most common cutaneous manifestations of IBD are erythema nodosum (EN) and pyoderma gangrenosum (PG). The purpose of this study was to characterize the relationship between EN and PG and pediatric IBD using the large Improve Care Now network (ICN) database.
