Pearly penile papules. A statistical study of incidence

Pápulas Perláceas Penianas: Apresentação Clínica Atípica em Criança

“…Tipicamente são assintomá-ticas. Glicksman et al 10 relataram um único caso com sensibilidade intermediária das lesões; porém, o autor afirma que as sensações podem ser subjetivas. No caso clínico descrito, o paciente queixava-se de prurido e, apesar de ser uma sintomatologia subjetiva, não foram encontrados relatos equivalentes em nossa busca.…”

Pearly penile papules: a review

“…Pearly penile papules (PPP) 1 have been called Tyson glands, 2 hirsutoid papillomas, 3 papilla in the corona glandis, 4 hirsutis papillary corona of the penis, 5 corona capilliti, 6 and pink pearly papules 7 by different workers.…”

Variations in Penile Anatomy and Their Contribution to Medical Mischief

“…4) is the most extensive I have seen, and it can be seen that the papules not only cover the corona, but also extend over much of the dorsal surface of this man's glans; this must be rare, as I have not seen any others like it nor read any other account of such a spread. While Buschke reported an incidence of 6% prominent and 8% total papules in 435 subjects in 1909, 24 later papers have found much higher incidences; e.g., 14% in Singapore, 26 20% of 229 subjects in Texas, 22 30% in 840 clinic patients in Detroit, 27 33% in 642, 19-year-old Swiss men, 28 and 48% in 200 clinic patients in Cambridge. 25 The last series in Cambridge was also counted by the extent of coverage of the corona: few and small, 35%; small and extending around the corona, 9%; moderate to large and extending around the corona 4%.…”

“…It is, therefore, strange that, in spite of their entering the medical literature in a report by Littre and Morgagni in 1700, 20 their histological nature was resolved 300 years later. 5,21,22 Since that time, they have appeared from time-to-time in reports making simple observations in man and speculations such as their being a nerve organ. 23 The prominent neuroanatomist Bielschowsky was able to show in 1909 that no nerve structures were associated with them in man and this has been confirmed.…”

“…23 The prominent neuroanatomist Bielschowsky was able to show in 1909 that no nerve structures were associated with them in man and this has been confirmed. 22 Buschke 24 seems to have been the first anatomist to have compared their infrequent occurrence in man with their normal appearance in other mammals, such as felines, pigs and primates. We have shown that, in the chimpanzee, these papules are a normal feature (spine-like) and are associated with nervous structures.…”
