Diagnostic Considerations

A Becker nevus on the upper trunk in a peripubertal male is difficult to confuse with other pigmented lesions.

Occasionally, a congenital Becker nevus may simulate congenital melanocytic nevus or nevus spilus, necessitating histologic examination to distinguish between lesions.

A Becker nevus without hypertrichosis may resemble a café au lait patch or postinflammatory hyperpigmentation.
