L66: Cicatricial alopecia [scarring hair loss]

L66.4: Folliculitis ulerythematosa reticulata

Small, lacy or striped dents are visible on the skin of both your cheeks. This is a long-term, but usually harmless condition. The cause is unknown.

Other skin changes, such as calluses, can often be found in other parts of the body. These callused areas are on the surface of the skin. As a result, the skin often feels rough. The extensor sides of the arms or legs, for example the elbows or knees, are often affected.
