Erythema Dyschromicum Perstans

Ashy dermatitis is a skin condition characterized by grayish or bluish flat patches that appear mainly on the trunk, neck, and arms. It is also known as erythema dyschromicum perstans.

How it is recognized: the patches are usually symmetrical, with borders that are sometimes somewhat defined, and they generally cause no pain or itching. Their distinctive color is what stands out the most.

Usual course: it tends to progress slowly and chronically, with gradual changes in color over time.

Which specialist evaluates it? The dermatologist is the one who examines this type of patch and distinguishes it from other pigmentation changes. If you notice persistent changes in the color of your skin, the best thing to do is bring it up during a visit.
