Furunclehttps://en.wikipedia.org/wiki/Boil
Furuncle (boil) is a deep infection of the hair follicle, most commonly caused by the bacterium Staphylococcus aureus. It produces a painful, swollen area on the skin due to an accumulation of pus and dead tissue.

Boils appear as bumpy, red, pus‑filled lumps around a hair follicle; they are tender, warm, and painful. When a boil is ready to drain, a yellow or white point can be seen at its center. In severe cases, fever, swollen lymph nodes, and fatigue may occur.

Boils can develop on the buttocks or near the anus, the back, neck, abdomen, chest, arms, legs, or even in the ear canal. When they occur around the eye, they are called styes.

Squeezing or cutting a boil at home should be avoided, as it can spread the infection. Antibiotic therapy may be recommended for large or recurrent boils, or for boils in sensitive areas such as the groin, breasts, armpits, nostrils, or ears.

  • Antibiotic treatment is needed because the infection can progress to cellulitis.
  • The severe form of folliculitis is called a furuncle.
  • Antibiotic treatment is necessary as it can progress to cellulitis.

A carbuncle is a contiguous collection of two or more furuncles. A carbuncle is an infection of the hair follicle(s) that extends into the surrounding skin and deep underlying subcutaneous tissue. They typically present as an erythematous, tender, inflamed, fluctuant nodule with multiple draining sinus tracts or pustules on the surface. Systemic symptoms are usually present, and regional lymphadenopathy may occur. They can arise in any hair-bearing location on the body; however, they are most common in areas with thicker skin such as the posterior neck, back, and thighs. A carbuncle can start as a folliculitis, which, if left untreated, can lead to a furuncle, and when multiple furuncles are contiguous, it becomes classified as a carbuncle. Carbuncles can be solitary or multiple.
