Epidemiology of hidradenitis suppurativa in Germany - an observational cohort study based on a multisource approach.

This population-based study analyses the prevalence and incidence of HS in Germany. The coding prevalence of 0.03% observed in two independent SHI data sets is lower than expected. The findings of considerable potential misdiagnosis add to the underdiagnosis of HS in general and underline the need for future strategies to early detection and valid diagnosis of HS.
