Abstract

Human papillomaviruses (HPVs) are epithelium-tropic viruses associated with several cutaneous, epithelial, and mucosal lesions. The oncogenic potential varies considerably among the more than 70 different genotypes so far identified. HPV 6 and 11 are generally found in benign genital condilomata or laryngeal papillomas, but they have been sporadically associated with genital malignancies. Polymerase chain reaction (PCR) primed by degenerated consensus oligonucleotides (from a late region of the HPV genome) allows one to amplify a broad spectrum of HPV, whereas the amplification with specific primers is restricted to a limited number of HPVs. Therefore, the restriction fragment length polymorphism assay permits one to identify the HPV type present in the PCR product. We report a case of an invasive verrucous carcinoma of the penis associated with HPV 11, a type previously considered noncarcinogenic.

Case report

A 58-year-old man was referred to the dermatologic clinic of the University of Rome “La Sapienza,” Rome, Italy because of the presence of a genital neoformation. Clinical examination revealed the presence of a large, nodular, exophytic lesion measuring 3 × 5 cm in diameter and involving the entire glans and infiltrating the entire penis. The remaining clinical examination revealed no abnormalities.

The patient attributed the occurrence of the symptomatic disease to about 2 months previous to

Comment

As shown in Figure 1, the verrucous carcinoma sample exhibits the same RFLP pattern as does HPV 11. After digestion with the restriction enzyme AluI (Fig. 1A), it was possible to observe that the sample does not belong in the HPV 16, 18, 31, or 33 group, but in the HPV 6 or 11 group. A second digestion with NsiI (Fig. 1B) allowed us to establish that the verrucous carcinoma HPV corresponds to HPV 11. These results were unexpected: HPV 11 had never before been associated with such an aggressive

    HPV-related precancerous lesions are associated with persistent HPV-16 and HPV-18 infection. Giant condyloma is associated with HPV-6 and HPV-11 [80]. Studies have estimated that approximately 60–100% of in situ (penile intraepithelial neoplasia [PeIN]) lesions are positive for HPV DNA [81–85].

    HPV-related precancerous lesions are often associated with persistent HPV type 16 and 18 infection. Giant condylomas are associated with HPV 6 and 11 subtypes.48 In a large multicenter study of HPV DNA prevalence in penile cancer, HPV DNA was detected in 100% of condyloma cases, 90% of dysplasia cases, and 42% of penile carcinoma cases.

    In penile carcinoma in-situ (figure 2) early carcinogenic changes are largely unknown and P53 alterations have not been seen.4 The papillary variant of squamous-cell carcinoma (SCC; figure 3) and the verrucous variant of penile SCC (figure 4) are HPV-independent neoplasms (or have undetectable HPV)5,6 showing early TP53 mutation7,8 with rapid accumulation of mutagenic events affecting unknown genetic pathways. However, the basaloid variant (figure 5) and warty variant of SCC (figure 6) are HPV-dependent neoplasms7,8 with a strong association between type of SCC and infection with HPV 16 or 18.7
