Hidradenitis suppurativa (hidradenitis) is a condition marked by small and often painful lumps under the skin that appear red or darker than one’s natural skin color. People with hidradenitis suppurativa usually notice flare-ups in areas of skin that contain hair follicles, oil glands and sweat glands that react to infection, inflammation and/or swelling. Most often found in the armpits, the groin and the anal area, hidradenitis can also occur in folds of skin where skin rubs together, such as between and below the breasts, between and below the buttocks, and on inner thighs.

Because of the extreme appearance and associated discomfort of hidradenitis suppurativa, people who experience occasional, frequent or chronic flare ups can learn about a variety of treatment options from the licensed professionals at California Skin Institute. Hidradenitis suppurativa is also known as acne inversa, which refers to large acne flare ups that can occur under the skin in an inward or downward direction.

The exact cause of hidradenitis suppurativa is not known definitively. Although smoking and obesity are known to be associated with hidradenitis suppurativa, risk factors include age and gender (most common among women 18-29 years old) and family history.

Your board-certified physician or advanced practitioner at California Skin Institute can help you understand what triggers your hidradenitis suppurativa and can inform you of various treatments that range from topical and laser applications to surgery
