What is high risk hpv
In order to find out the HPV type that your son has, a sample of the papilloma would have to be tested. Generally, RRP patients have HPV types 6 & 11, and more rarely type 16 (1-2%). Type 16 is usually very rare. Although 18 is mentioned in some of the literature, no HPV researcher that RRP ISA talked to has ever seen type 18 RRP. Usually, children exhibit a more aggressive disease & adult on-set patients exhibit non-aggressive disease, but this is not always the case. While I do not have a definite definition of aggression, some view aggressive cases as requiring 4 or more surgeries per year. Tom Broker, PhD presented data at the last RRP meeting confirming that HPV 11 tends to be more aggressive than 6.
