The goal of this observational study is to learn about the link between work-related sun exposure and a specific type of skin cancer called melanoma in people living in the Modena area, Italy. The main questions it aims to answer are: * Is there a connection between working outdoors and developing types of melanoma that are linked to long-term sun exposure? * Can we use recent criteria from the Italian workers' compensation authority (INAIL) to better identify and report these melanomas as occupational diseases? Participants in this study will: * Be patients of the Modena University Hospital Dermatology Clinic who are already undergoing a skin biopsy for a suspected lesion. * Take part in a one-time interview with a trained healthcare worker. Answer questions about their: * Job history and specific work locations (to calculate local UVR exposure). * Sun exposure habits at work and in their free/holiday time. * Use of sun protection (e.g., sunscreen, protective clothing). * Use of tanning beds. * Natural skin color and tendency to sunburn (and other elements to determine their specific skin phototype). * Other personal and family health factors. Researchers will compare two groups: * Cases: 120 participants who are diagnosed with melanoma after the biopsy. * Controls: 180 participants who screened negative for melanoma but may show another skin condition. By comparing these groups, researchers aim at better understanding the role of outdoor work as a risk factor for specific melanoma subtypes. For participants diagnosed with a melanoma that is likely linked to their job, the study team will promote its reporting as an occupational disease.
