What are Folliculitis and Furuncle (Boil) ?

What are the presenting features of Folliculitis ?
- The folliculitis usually affect the scalp, face, trunk and legs. The hair follicles are surrounded by either small pockets of pus or small red lumps.
- Sometimes, many adjacent hair follicles are affected at the same time giving rise to what is commonly known as boil or furuncle. In such instances, surgical drainage of the pus may have to be carried out besides antibiotic tablets.
- Carbuncle: There are many infected follicular openings in contrast to a furuncle
