Clinical Dermatology


A boil (colloquially) is an inflammatory nodule of the skin. It is usually created by the bacteria Staphylococcus aureus, which penetrates the skin through the hair follicles. These nodules usually appear at points of friction, at the bends of the joints or at points where the skin causes folds.

The nodule is intensely red, particularly painful and, over the course of the disease, displays a white protrusion corresponding to a collection of pus.

The incipient infection is treated by the dermatologist by administering oral antibiotic treatment and in special cases by opening and cleaning the purulent area for relieving the symptoms fast.
