Abstract

Becker's nevus has been known as a sudden onset of hyperpigmentation on shoulder or arm in the second decade of life with slow peripheral extension and later development of hypertrichosis. We observed two cases of typical Becker's nevus which was confirmed by characteristicclinical and histopathological findings. One was 45-year-old male who has a patch of hyperpigmentation and hypertrichosis on left upper arm at birth, the other was 2()-year-old male who developed on right shoulder after sunburn which is a salient feature by Becker's initial description.
