The presence of human papilloma virus (HPV) DNA sequences of types 6, 11, 16, and 18 was determined by in situ hybridization under stringent conditions on archival paraffin-embedded tissue sections in eight condylomata acuminata observed in children below the age of 12 years. Viral sequences were detected in seven of eight cases: all of them contained HPV 6, four contained also HPV 11, and one contained HPV 16 and 18. Papilloma virus common antigen was detected in only three of eight cases, all of them being positive also by in situ hybridization. We conclude that most condylomata acuminata in children are associated with the same types found in anogenital lesions in adults. Since little is known about the long-term significance of genital condylomas in children the identification of the papilloma virus type may prove to be important as a prognostic tool particularly in patients infected with HPV types 16 and 18, thought to have high oncogenic potential.
