ABSTRACT

Observations:

Becker's nevus is a relatively common acquired focal epidermal melanotic hypermelanosis. The disease is usually characterized by a unilateral, hyperpigmented, hypertrichotic patch on the upper trunk or proximal upper extremities of males. Becker's nevus, bilateral and symmetrical involvement has been reported rarely. Here is presented a rare case of bilateral, symmetrical, giant, non-syndromic Becker's nevus.
