The incidence of human papillomavirus (HPV) DNA in archival formalin-fixed, paraffin-embedded tissue sections from verrucous carcinoma of the larynx was determined using polymerase chain reaction (PCR) with consensus primers and by in situ hybridization designed to detect HPV types 6/11, 16/18, 31/33/35. HPV DNA was detected in 17 (85%) of 20 tissue samples by PCR; none of the 20 samples were positive for the seven genotype types tested by in situ hybridization. PCR is a valuable tool to detect HPV and therefore will significantly clarify the importance of HPV in squamous mucosal disorders.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D002291	Carcinoma, Papillary	A malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. (Stedman, 25th ed)	Carcinomas, Papillary,Papillary Carcinoma,Papillary Carcinomas

D005784	Gene Amplification	A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.
