BackgroundAlthough recent hidradenitis suppurativa studies have shown that early-onset disease is associated with a positive family history and more widespread disease, research in pediatric hidradenitis suppurativa is limited.MethodsThirty-three children diagnosed with hidradenitis suppurativa during an 18-month period were included in this institutional review board-approved, retrospective chart review. Information on demographic characteristic, family history, and timing of onset (prepubescent vs postpubescent) was extracted. The Fisher exact test, Cochran-Armitage exact trend test, and chi-square test were used to examine the association between prepubescent or postpubescent onset of hidradenitis suppurativa and sex, disease severity, and family history.ResultsA significantly higher percentage of patients with postpubescent onset were female (85.7%) than male (14.3%), whereas those with prepubescent onset were more likely to be male (58.3%) than female (41.7%; P = .02). Associations between disease onset and positive family history of hidradenitis suppurativa (P = .47) or higher Hurley stage of disease (P = .15) were not statistically significant.ConclusionBoys are more likely to have prepubescent onset of hidradenitis suppurativa and girls to have postpubescent onset. This shift in sex distribution is unexplained, but we hypothesize that, whereas the role of ovarian hormones in the pathogenesis of HS may underlie much of adult-onset disease, it is less important in prepubescent disease.© 2018 Wiley Periodicals, Inc.
