What are the small white bumps growing inside the foreskin?

Small white bumps on the foreskin are commonly indicative of pearly penile papules. These lesions typically appear as white, acne-like bumps beneath the coronal sulcus of the glans penis. Characteristically, they are flat, pinhead-sized papules that do not significantly elevate above the skin surface; they occur in clusters and are usually pale yellow, though occasionally pale white. They generally cause no pruritus (itching) and have no adverse effect on health or fertility. If necessary, they can be removed using laser therapy. Treatment should be undertaken only under the guidance of a qualified physician.
