Hidradenitis suppurativa (HS) is a disease that usually begins as pimple-like bumps on the skin. The pimple-like bumps tend to develop in places that everyday pimples do not appear. HS is most common on the underarms and groin.
Sometimes hidradenitis suppurativa is confused with other similar-looking skin conditions such as common boils, collections of pus (abscesses), skin infections and ingrowing hairs. Other diseases can cause tunnels (channels) known as sinus tracts-for example, Crohn's disease.idradenitis suppurativa is a long-term (chronic) skin condition. The cause is unknown. Inflammation of the apocrine sweat gland-bearing areas leads to painful and recurrent boils and abscesses.
