Abstract
The presence of human papillomavirus (HPV) DNA of types 6, 11, 16, 18, 31 and 33 was determined by in situ hybridization on archival paraffin-embedded tissue sections in 21 condylomata acuminata observed in patients aged 20 or less. HPV DNA was detected in 17 of 21 cases: all of these contained HPV 6, five also contained HPV 11, and one also contained HPV 16 and 18. HPVs 31 and 33 were not observed. Among 21 cases, 4 cases were in children under 6 yrs one of whom had a history of sexual abuse. The hybridization data indicate that condylomata acuminata in young people are associated with the same HPV types found in anogenital lesions in adults.
