[How I treat...hidradenitis suppurativa].

Hidradenitis suppurativa is a chronic and debilitating inflammatory disease. It presents as recurrent abcesses, sinus tracts and scarring. The condition usually develops in the axillae and groins, and more rarely involves the breasts, perineum and buttocks. There are many myths around hidradenitis suppurativa including its origin and pathomechanisms. Some antibiotics as well as corticosteroids and other immune downregulators are poorly effective in this stubborn condition. By contrast, TNF-alpha antagonists appear promising. Radical surgery is another effective option.
