One condition that often leaves post- inflammatory hyperpigmentation (PIH) is acne. Notice the PIH ranging from pink to dark brown. The dermal deposition of melanin can cause PIH for several months or longer.

PIH appears with a wide range of dark discoloration and the level of hyperpigmentation often depends upon the intensity of preceding inflammation or injury. As a physician you might have significant management challenges, but it is important to note that pigment disorders can cause even more distress to the patient.
