Four patients diagnosed with PPPs were treated with PDL. Each patient reported little to no discomfort during the procedure. Minimal bruising was found in all 4 patients, which diminished over time. One patient stated slight discomfort after the procedure; this however, resolved in a weeks' time. Complete clearance of the papules was noted after 2 to 3 treatments in 2 patients and a reduction of the papules in 2 patients.
The incidence of pearly penile papules reportedly ranges from 8-48%. [2] Several reports suggest an increased incidence of pearly penile papules in uncircumcised versus circumcised men (22% vs 12%, respectively). One study found an increase in frequency in black versus white men, in those circumcised (21% vs 7%, respectively) and uncircumcised (44% vs 33%, respectively).
