transitional papillomas of the sinonasal region and 9 maxillary
squamous cell carcinomas. "Thirteen (68%) of the papillomas and none of
the carcinomas contained HPV genome. Six (32%) of the papillomas and 4
(44%) of the carcinomas had an aneuploid DNA content. The relative DNA
content (DNA index) of the aneuploid maxillary carcinomas was larger
than that of aneuploid papillomas (p = 0.004). Three of the papillomas
underwent malignant transformation, all three of which contained HPV
type 16 DNA; two were also aneuploid. Data indicate that papillomas
containing HPV type 16 DNA have a tendency (p = 0.06) to undergo
malignant transformation, and that this tendency is greater if DNA
aneuploidy or HPV type 11 DNA is also present (p = 0.02)."

HPV infections in benign and malignant sinonasal lesions.
Syrjšnen KJ. J Clin Pathol 2003;56:174–81. Review. "To date, 33.3%
of sinonasal papillomas and 21.7% of sinonasal carcinomas analysed have
been shown to be positive for HPV. Many elements of the data parallel
the observations made in HPV lesions at other mucosal sites, such as
malignant transformation and frequent recurrence after radical
treatment; the fact that low risk HPV types 6 and 11 are usually
confined to benign lesions, whereas the reverse is true for the
oncogenic HPV types 16 and 18; and the presence of squamo–columnar
junctions and squamous cell metaplasia in the sinonasal system. The
discrepancies reported by several studies might result in part from
technical reasons, but it is also possible that sinonasal lesions have
a heterogeneous aetiology (HPV related and non-related) and/or that
some novel (yet unidentified) HPV types exist in these lesions, which
are detected by some studies but not by others."

patients with SCC, HPV sequences were detected in two patients, whereas
one patient was negative for the oligoprobes tested. Of the 11 patients
diagnosed only with IP, 1 patient was positive for HPV DNA (HPV type
11)... and the relative level of E7 to E5 transcripts indicates
integration of the viral genome. These findings are suggestive of HPV
having an active role in the lesion."

"HPV detection was performed in only 22 of the 115 cases of PSCC (19%),
and 11 of the 22 cases (50%) are related to this virus. The majority of
cases related to HPV are produced by low-risk HPV type 6 followed by
high-risk HPV type 16. Today, the association of HPV with PSCCs seems
unclear because in the majority of patients tests were not performed
for the detection of the HPV. This association should be clearly
established to make a correct diagnosis and propose the best
therapeutic strategies, such as new vaccines."
