BACKGROUND: Hidradenitis suppurativa (HS) and pyoderma gangrenosum (PG) are reported to coexist, although the prevalence of PG among patients with HS has not been systematically evaluated. OBJECTIVE: To evaluate PG prevalence among patients with HS. METHODS: Cross-sectional analysis of adults with PG among patients with HS and patients without HS through use of electronic health records data from a population-based sample of 55 million patients. RESULTS: The prevalence of PG among 68,232 patients with HS was 0.18% (125 of 68,232), compared with 0.01% (1835 of 31,435,166) among those without HS (P < .0001). Prevalence was markedly higher among patients with HS and Crohn's disease (CD) (3.68%) than among patients with HS but without CD (0.12%). The odds of having PG were 21.14 (95% confidence interval [CI], 17.51-25.51) times greater among patients with HS than among those without HS. Patients with HS with CD had 12.38 (95% CI, 9.15-16.74) times the odds of having PG than did patients without HS but with CD. Among patients without CD, compared with patients without HS, those with HS had 26.51 (95% CI, 21.07-33.36) times the odds of having PG. LIMITATIONS: We could not establish HS phenotype among those having coexistent PG, nor could we distinguish syndromic from nonsyndromic cases. CONCLUSION: Patients with HS have an increased prevalence of PG, regardless of CD status. Painful ulcerations among patients with HS warrant additional evaluation for PG.
