<unk>  (PPPs) are normal small bumps on the human penis or human clitoris. They vary in size from 1–4 mm, are<unk>  or flesh-colored, smooth and dome-topped or filiform, and appear in one or several rows around the corona, the ridge of the head of the penis and sometimes on the<unk>  shaft. They are painless, non-cancerous and not harmful. PPPs are a type of angiofibroma. Their function is not well-understood. They are sometimes described as vestigial remnants of<unk>  spines, sensitive features found in the same location in other primates. PPPs secrete oil that moistens the glans of the penis. They do not spread and often spontaneously regress. Diagnosis is by visualisation. On dermoscopy, the white-pink<unk>  appear in a cobblestone-like pattern and contain a central dotted or comma-shaped blood vessels. Cryotherapy or laser therapy are options for removal of PPP's. PPPs are common and occur in 14% to 48% of young males. They are more common in uncircumcised males. PPPs were first described in 1700 and the term<unk>  was coined in 1964. Some men find PPPs distressing to look at, owing to their resemblance to some sexually transmitted infections.
