Lichen planus.

Hello,
One possibility that presents with annular lesions on the penis is of lichen planus. Lichen planus is an inflammatory disease that affects the skin and the oral mucosa, and presents itself in the form of papules(flat spots) or rashes. Treatment is available only on prescription and consists mainly of steroids, retinoids, hydroquinone and phototherapy.
