Epidemiology

Etiology

Pathophysiology

Blockage of hair follicle → dilation and rupture → spilling of follicular contents into dermis → inflammatory response → abscess formation and destruction of the pilosebaceous unit

Clinical features

• Localized in intertriginous areas containing apocrine glands (most commonly the axillae, groin, inner thigh, perineal and perianal areas)
• The first lesion is usually a solitary painful inflammatory nodule that progresses to an abscess that may open or regress spontaneously.
• Sinus tracts may form between multiple recurrent nodules and drain foul-smelling, seropurulent discharge.
• Development of open and closed comedones
• Scarring ranges from small, individual acneiform scars to thick scarred plaques that affect larger areas of skin.
