Relationship between the clinical course and HPV typing of recurrent laryngeal papillomatosis. The Red Cross War Memorial Children's Hospital experience 1982-1988.
During the period 1982-1988, 20 new cases of laryngeal papillomatosis in children were seen at The Red Cross War Memorial Children's Hospital. HPV typing of biopsy specimens was performed. Their clinical course was reviewed and age at presentation ranged from 1 to 10 years. There was no correlation between age and either aggression or a prolonged clinical course. HPV DNA was identified in all 20 cases (100%). Fifteen (75%) were HPV Type 11 and 5 (25%) were HPV Type 6. There were no mixed infections. HPV Type 6 infection was more clinically aggressive than HPV Type 11 infection. The intensity of the virus signal in the biopsy specimens was not in general indicative of the clinical behavior of the disease, although two children with particularly strong intensity exhibited aggressive disease. It is suggested that identification of HPV type 6 infection has prognostic significance.
