Recurrent inflammatory disease of the skin folds — where lesions return to the same sites, drain, and in time build tracts and scar.
The pattern this Centre exists for:
recurrent inflammation → nodules and abscesses → drainage → chronicity → sinus formation and scarring
These conditions share a trajectory, not just a location. What makes them one clinical area is that each follows the same arc: inflammation that recurs at a fixed site, drains, and progressively converts soft tissue into structure. Treating the individual lesion does not interrupt that arc, which is why all of them recur after drainage or excision.
Each remains a separate disease with its own pages, staging and treatment approach. The Centre is how they are organised, not a single protocol.
The flagship condition of this Centre, with the deepest clinical library on the site.
Open the Hidradenitis Suppurativa pages →Recurrent sinus disease of the natal cleft, with the same drainage-and-recurrence pattern.
Open the Pilonidal Disease pages →Abscesses that keep returning to the same site — frequently HS that has not yet been named.
Open the Recurrent Abscesses pages →Also seen in this Centre: Pyoderma · Panniculitis · Erythema Nodosum · Non-healing Wounds & Ulcers
Acne Inversa is the same disease as Hidradenitis Suppurativa, not a separate programme. If you arrived on that term, the HS pages are the ones you want.
