Pigmentary demarcation lines (PDL), also known as Futcher lines or Voigt lines. Physiological (natural) abrupt transition lines from areas of deeper skin color to areas with lighter color. They present sharp demarcation lines that occur on different parts of the body. Considered as an ancestral remnant, where the back skin is pigmented more than the front, providing better protection from the sun. Eight pigmentary demarcation lines have been described and categorized according to the letters A-H. Three of them are facial patterns and the rest are body types. Pigmentary demarcation lines are very common nonpathological pigmentations in dark skin which is usually under diagnosed by dermatologists.
