Hidradenitis suppurativa , also known as acne inversa, is a chronic skin disease characterized by recurrent boil-like lumps nodules under the skin. The nodules become inflamed and painful. They tend to break open rupture , causing abscesses that drain fluid and pus. As the abscesses heal, they produce significant scarring of the skin.

A boil , also called a furuncle , is a deep folliculitis , infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus , resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. Almost any organ system can be infected by S. Boils are bumpy, red, pus -filled lumps around a hair follicle that are tender , warm, and very painful. They range from pea-sized to golf ball-sized. A yellow or white point at the center of the lump can be seen when the boil is ready to drain or discharge pus.
Pimples tend to be skin problems most associated with the face, though they can form on your back, pubic area, and just about anywhere on the body — including the anus. That can lead to infection and other complications. The bump you feel may also be a different health concern, including a hemorrhoid or a cyst that will require treatment by a healthcare professional. There are different types of pimples, including pustules , which are small raised pink or red bumps that contain pus. Larger papule -like bumps embedded in the skin are called nodules , while larger, pus-filled lumps are called cysts.
