Hidradenitis Suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition affecting areas of the body where skin rubs together, including the armpits, groin, buttocks and under the breasts. HS is more common in women and typically begins after puberty. At Define Clinic, our dermatologists assess and manage hidradenitis suppurativa with evidence-based treatment approaches tailored to each patient’s individual needs.

What are the symptoms of hidradenitis suppurativa?

HS may present as:

  • Painful, deep lumps or nodules under the skin
  • Recurring abscesses in affected areas
  • Scarring and sinus tracts over time
  • Persistent inflammation in the armpits, groin or buttocks

Symptoms vary in severity between individuals. Early assessment by a dermatologist is recommended to discuss appropriate management options.

How is hidradenitis suppurativa diagnosed?

HS is diagnosed through clinical assessment by a dermatologist. There is no single test for HS — diagnosis is based on the pattern, location and history of lesions. If you have been experiencing recurring painful lumps in typical HS locations, a consultation with one of our dermatologists at Define Clinic is recommended.
