'Pearly penile papules are multiple, small (about 1-3mm) papules running around the circumference of the crown of the glans (glands) penis. They typically develop in men aged 20 to 40, and around 10 per cent of all men are affected. They may be mistaken for warts, are not infectious and require no treatment.'
'Fordyce spots are small (1-5mm) bright red or purple papules that can appear on the glans (glands), shaft or scrotum and usually affect younger men. They may occur as a solitary lesion, but frequently appear in crops of 50 to 100. They are painless and not itchy, but may cause embarrassment because of their appearance, or a fear that they might be sexually transmitted. '
