Hyperpigmentation disorders present as skin that is discolored, blotchy, darker, or lighter than normal – this happens when the body produces too little or too much melanin. These disorders can be localized or can diffusely spread about the entire body. The most common types of genetic hyperpigmentation are birthmarks, macular stains, port wine stains, albinism, piebaldism, and freckles. Not all genetic skin colorations will appear at birth – some, like freckles, appear with sun exposure, while others, like melasma, may appear during pregnancy and in middle-age.
