L57: Skin changes due to chronic exposure to nonionizing radiation

L57.5: Actinic granuloma

This skin condition causes the many small papules to be skin-colored or reddish. The papules can merge with each other and form a kind of ring. The skin in the middle of this ring can cave in and be thinner than usual.

This skin condition is mainly found in areas exposed to a lot of sunlight. This includes the skin on the face or the backs of the hands.
