Hidradenitis suppurativa (HS) is a chronic skin condition characterized by the following key features:
- Inflammatory nodules and abscesses: These are painful, deep-seated boils that occur in areas with a high density of hair follicles, such as the armpits, groin, and buttocks.
- Scarring: The chronic inflammation can lead to scarring and the formation of tunnels under the skin.
- Recurrence: HS tends to be a recurring condition, with flares and remissions.
- Inverse involvement: The condition often affects areas where skin rubs against skin, such as the armpits, groin, and under the breasts.
- Association with other medical conditions: HS has been linked to other conditions such as obesity, smoking, and Crohn's disease.
