The Hidradenitis Suppurativa Foundation, Inc. (HSF) is a 501(c)(3) nonprofit public benefit corporation, dedicated to improving research, education, and the quality of life and care for individuals and families affected by Hidradenitis Suppurativa (HS).

HS is an inflammatory skin disease affecting an estimated 1-4% of the world population. The main features of HS include painful and chronically recurring, deep-seated follicular nodules, papules, pustules and abscesses, scarring, sinus tracts and recurrent discharge. The areas most commonly affected are under the arms, groin, buttocks, and under the breasts. The disease is variable and recurrent. It may occur as solitary or multiple lesions in one area, or in many areas. In more severe cases, there may be large areas of skin affected by recurrent, draining lesions.

The disease is often undiagnosed or misdiagnosed, with many patients experiencing substantial delay until a correct diagnosis is established. These issues compound the high morbidity and disabling nature of the disease. The challenges of timely diagnosis, quality research, community and patient education and improvements in patient care are all elements of the focus of the Hidradenitis Suppurativa Foundation.

Founded in 2005 and incorporated in the state of California, USA, the success of the Hidradenitis Suppurativa Foundation depends on financial support from research and development grants and from individual gifts and corporate/industry sponsorships. For more information on how you can support the HSF, please refer to the support section. Together with your help, the HSF hopes to make a difference in the lives of those who suffer with hidradenitis suppurativa. Your charitable donations to the HSF are tax deductible as allowed by law.
