Milky Red Areas (MRA) in Lichen Planopilaris

The Milky Red Areas (MRA) in LPP



Trichoscopy (scalp dermoscopy) involves the use of a hand held dermatoscope to better assess the scalp. It has proven helpful for managing a plethora of scalp diseases. 

The field of trichoscopy is filled with bizarre terms. This photo shows the milky red areas of lichen planopilaris. These milky red areas correlate with disease activity. The more milky red areas that are seen the more activity the patient has.
