Becker nevus, first described by Samuel William Becker in 1949, is a focal epidermal hypermelanotic disorder. It commonly presents as a unilateral hyperpigmented patch that is predominantly distributed on the upper trunk and proximal extremities and frequently associated with hypertrichosis. There have been few reports in the literature of Becker nevus with bilateral involvement; multiple Becker nevi is also unusual. Herein, we report a young man with two bilateral symmetrical giant Becker nevi, one on the trunk with extension to both arms and the second on the abdomen.
