A<unk>  is where a<unk>  infection drains onto the surface of the skin of the face or neck. This is uncommon as usually<unk>  infections drain into the mouth, typically forming a parulis ("gumboil"). Cutaneous<unk> es of<unk><unk>  tend to occur under the chin or mandible. Without elimination of the source of the infection, the lesion tends to have a relapsing and remitting course, with healing periods and periods of purulent discharge. Cutaneous<unk>  tracts may result in fibrosis and scarring which may cause cosmetic concern. Sometimes minor surgery is carried out to remove the residual lesion.
