Hidradenitis suppurativa (HS), sometimes known as acne inversa or Verneuil's disease, is a long-term dermatological condition characterized by the occurrence of inflamed and swollen lumps. [ 2 ] [ 3 ] These are typically painful and break open, releasing fluid or pus . [ 3 ]
Hidradenitis suppurativa is a chronic inflammatory skin condition, considered a member of the acne family of disorders. [6] It is sometimes called acne inversa. The first signs of HS are small bumps on the skin that resemble pimples, cysts, boils, or folliculitis.
In general, the disease often causes skin to darken near the affected area and raised bumps or papules to appear. [3] In addition, hair follicles can become damaged which cause hair loss. [ 3 ] Hidradenitis is very similar, but tends to have a secondary bacterial infection so that pus-draining sinuses are formed.
An associated skin disease favors recurrence. This may be attributed to the persistent colonization of abnormal skin with S. aureus strains, such as is the case in persons with atopic dermatitis. [16] Boils which recur under the arm, breast or in the groin area may be associated with hidradenitis suppurativa (HS). [17]
Scientists initially hypothesized that acne represented a disease of the skin's hair follicle, and occurred due to blockage of the pore by sebum. During the 1880s, they observed bacteria by microscopy in skin samples from people with acne. Investigators believed the bacteria caused comedones, sebum production, and ultimately acne. [206]
Toxic shock syndrome (TSS) is a condition caused by bacterial toxins. [1] Symptoms may include fever, rash, skin peeling, and low blood pressure. [1] There may also be symptoms related to the specific underlying infection such as mastitis, osteomyelitis, necrotising fasciitis, or pneumonia.
Connective tissue diseases are caused by a complex array of autoimmune responses that target or affect collagen or ground substance.

But, each type of skin infection caused by staph bacteria is different. A few common skin infections caused by staph bacteria are: Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin.
