What this trial studies

This observational study aims to gather comprehensive clinical and biological data on hidradenitis suppurativa (HS), a debilitating skin condition that is not well understood. By enrolling participants diagnosed with HS, the study will create a registry that characterizes the disease's features and outcomes. The collected data will help in developing a clinical classification system and identifying potential treatment options for HS. The study will include individuals aged 10 and older who can provide informed consent.
