[Papillomatosis coronae glandis. Frequency of occurrence and clinical picture].

The clinical picture of pearly penile papules (PPP) is described on the basis of the literature and the authors' own investigations. Although symptomless and without functional significance, PPP may lead to damaging therapeutic measures if not recognized as such by physician and patient. The incidence of PPP has been investigated in 642 19-year-old Swiss men originating from the same geographical region. PPP were found in 33%, in 9.2% as the major variant and in 23.8% as the minor variant.
