Hidrosadenitis Suppurativa is a chronic skin condition characterized by swollen, painful, inflamed lesions in the axillae, groin, buttocks and other parts of the body that contain apocrine glands. It is more commonly found in women and can be present under the breasts.

 

The hallmark of Hidrosadenitis Suppurativa is sinus tracts (which can become draining fistulas) in the apocrine gland body areas.
