Hidradenitis Suppurativa: Insights from pathogenesis to treatment

Hidradenitis suppurativa (HS) is an inflammatory disorder that is characterized by chronic deep-seated nodules, abscesses, fistulae, sinus tracts, and scars in the axilla, inguinal area, submammary folds, and perianal area. This disfiguring condition is accompanied by pain, embarrassment, and a significantly decreased quality of life. Although the mechanism of HS has not been entirely elucidated, lesion formation is believed to center around follicular hyperkeratosis within the pilosebaceous-apocrine unit. Recent research has provided new insight into the role of cytokines in the pathogenesis of HS, helping close some existing knowledge gaps in the development of this condition. This Article Collection brings together the most important recent findings on pathogenesis and treatments for this disease.
