Introduction: The worldwide incidence of melanoma has increased in the last 40 years. Our aim was to describe the clinic-pathological characteristics and outcomes of three cohorts of patients diagnosed with melanoma in a Latin-American cancer institute during the last 20 years. Methods: We evaluated three retrospective patient cohorts diagnosed with melanoma at Instituto Nacional de Enfermedades Neoplasicas (INEN), a public hospital in Lima, Peru, for the years 2005–2006, 2010–2011, and 2017–2018.
