Medical Definition of Hyperpigmentation
Hyperpigmentation: Dark spots on the skin. Hyperpigmentation is primarily a cosmetic concern that can be covered with makeup, although in some cases (such as the cafe au lait spots associated with neurofibromatosis) it can be a sign of an underlying medical problem.Source: MedTerms™ Medical Dictionary
