It can be skin-colored (pale yellow) or contain pigment (brown, even black) and be flat or raised. The cause of its appearance is not known; there is a genetic predisposition in certain people. They are benign and not contagious but it is important to go to the dermatologist to diagnose them since they can have pigment and be confused with other skin lesions. They can be removed if they cause discomfort because they become irritated, if they bleed because clothing rubs against them, or simply for aesthetic reasons. Removal is usually simple and there are several methods: freezing with liquid nitrogen (cryotherapy), curettage or curettage (with a special instrument), burning with electrical current (electrocauterization) or vaporizing the lesion with a laser (ablation).
