In the 1970s, human papillomaviruses (HPV) were ascertained as the aetiologic agents of cervical carcinoma. Subsequently, an association with HPV was established in other epithelial tumours, including squamous cell carcinoma of the head and neck (HNSCC). HPV has demonstrated a high potential for inducing oropharyngeal tumours, with HPV-16 infection posing a significant oncogenic risk. People living with HIV (PLWH) are identified as being at a higher risk of HPV infection and the subsequent development of HPV-associated tumours of the oropharynx. We present two patients under the care of the Department of AIDS with long-term HIV infections who were newly diagnosed with HPV-associated carcinomas of the tonsils. Both patients had been on antiretroviral therapy (ART) for over 15 years, achieving optimal viral suppression for more than 10 years. Chemotherapy and radiation therapy were employed in the treatment of the carcinomas. Throughout the neoplastic disease treatment, both patients maintained optimal viral suppression for HIV. The presented cases underscore the fact that despite achieving long-term optimal viral suppression of HIV, people living with HIV remain susceptible to the development of HPV-associated neoplasms.
