[Looking for "lost occupational cancers": a systematic evaluation of occupational exposure in a case series of cutaneous squamous cell carcinomas in Italy].

Background: 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.

Objectives: To asses the proportion of Squamous Cell Carcinomas (SCC) cases with a previous occupational exposure to carcinogens.
