Abstract
Cutaneous carcinomas are tumors with a potential occupational etiology due to exposure to established carcinogens such as polycyclic aromatic hydrocarbons (PAH), ionizing radiation, ultraviolet (UV) radiation and arsenic. The occupational origin of such neoplasms is hugely underestimated in Italy.To asses the proportion of Squamous Cell Carcinomas (SCC) cases with a previous occupational exposure to carcinogens.We systematically evaluated occupational exposure in a series of consecutive cases, discharged in the period 2010-11 from the Dermatology Unit of Varese Hospital, Italy, with a histological diagnosis of SCC. Through a structured telephone interview we identified patients with a potential exposure to skin carcinogens. As a second-level step, an extensive evaluation by an occupational physician was performed to assess the occupational etiology in those selected cases.105 patients were identified (65 men). 15 male cases out of a total of 85 patients who did the telephone interview, revealed a potential occupational exposure; 7 cases were confirmed as occupational cancers after second-level evaluation (proportion of male occupational cases = 13.2\%). UV radiation and PAH were recognized as major causal agents. Applying those results to the national incidence data, we estimated a number of 700 annual occupational cases, 100-fold more than the cases currently evaluated by the Italian National Workers Compensation Authority.Our results revealed that occupational SCC is still at present a substantially "lost disease" in Italy. Greater attention and enhanced collaboration between specialists is thus needed to overcome this tendency.
