OBJECTIVES: Neoplasms associated with human papillomavirus (HPV) infection occur at increased frequency in patients with HIV infection/AIDS. Although laryngeal squamous cell carcinomas (LSCCs) in HIV-positive patients are uncommon, a higher incidence of this malignancy in HIV-positive patients than in the general population has been reported. As a proportion of LSCCs are associated with HPV in the general population, the clinicopathological features of a series of LSCCs developing in HIV-positive patients were evaluated to investigate the possible relationship with HPV infection, and infection with other oncogenic viruses. METHODS: All HIV-positive patients with LSCC diagnosed at a single institution from 1998 to 2007 were retrospectively evaluated. The clinicopathological features were analysed and tissues were tested by polymerase chain reaction (PCR), using the short PCR fragment 10 (SPF10) primer, a highly sensitive method for HPV DNA detection. Immunohistochemical studies for HIV p24, p16(INK4a) and p53 were performed. Epstein-Barr virus (EBV) and human herpes virus 8 (HHV-8) were also investigated. RESULTS: Six out of 4987 HIV-infected patients seen in this period in the Infectious Diseases Department developed LSCC (median age 41.5 years; male to female ratio 1:1). All patients were heavy smokers and the tumours presented at an advanced clinical stage. HPV was not detected in any tumour, not even in two patients with coexisting HPV-associated gynaecological neoplasm. Staining for HIV p24 and p16(INK4a) was negative, whereas p53 was positive in half the cases. EBV and HHV-8 were also negative. CONCLUSION: LSCC developing in HIV-positive patients is an infrequent neoplasm, not usually associated with HPV infection. It develops in young, heavy smokers and presents at an advanced clinical stage.
