Skin Cancers in People Living with Human Immunodeficiency Virus (HIV) Infection.

The advent of combination antiretroviral therapy has led to significant reductions in HIV-related morbidity and mortality and, conversely, an increasing incidence of chronic diseases, such as cancer. This study aimed to assess the incidence of skin malignancies in a cohort of people living with HIV (PLWH) compared to HIV-uninfected individuals (HUPs). : Between April 2023 and April 2025, PLWH attending the Infectious Disease Unit at Policlinico of Foggia, Italy, were invited for skin cancer screening (cases). During the same period, patients visiting the Dermatology Unit were asked to undergo skin cancer screening and a rapid HIV test. Those who tested negative were included as controls. Suspicious lesions were surgically excised at the Plastic Surgery University Unit and examined by a dermatopathologist. We enrolled 91 cases and 91 controls. Precancerous and cancerous skin lesions were detected at similar rates in PLWH and HUPs (12% vs. 13.2% and 7.6% vs. 8.7%). The total number of cancerous and precancerous lesions was higher in the PLWH group. In both groups, basal cell carcinoma was the most common tumor. Squamous cell carcinoma, basosquamous carcinoma, and dermatofibrosarcoma protuberans were found only in PLWH. : The higher risk of multiple and rare skin cancers in PLWH should be recognized by healthcare providers and patients. PLWH should have regular skin cancer screenings, especially if they have additional risk factors such as a history of extensive ultraviolet radiation exposure.
