Constitution of a Prospective Cohort of Patients With Acute Suppurative Hidrosadenitis Followed in the Great West: the COVER Cohort (Verneuil Cohort)

Study Overview
=================
Brief Summary
-----------------
Our primary objective with this cohort will be to define the different phenotypes of acute hidrosadenitis, the characterization of which is essential to define suitable therapeutic approaches. Indeed, our recent data allow us to note that there would be different phenotypes of acute hidrosadenitis and therefore different pathologies inducing different follow-ups and care.
