Introduction: Melanoma is a malignant neoplasm associated with excessive ultraviolet (UV) radiation exposure [1]. Although it accounts for 5% of malignant skin cancers, it is responsible for more than 75% of global deaths related to these neoplasms [2,3]. Considering the importance of case reporting for understanding this disease, this study aimed to analyze the distribution of melanoma across the five geographic regions of Brazil. Methodology: Data were collected from DATASUS between 2 April 2025 and 3 June 2025, extracting notifications recorded between 2013 and 2023. Variables considered were geographic region, sex, age group, and skin color/race. Results: During the study period, 20,087 cases were reported. The Southeast concentrated 8771 (43%), followed by the South with 6731 (34%), the Northeast with 2916 (15%), the Midwest with 1193 (6%), and the North with 537 (2%). There was a predominance among males, with 11,550 (57.5%) compared to 8537 (42.5%) in females, with the Southeast and South together accounting for 76% of cases in both sexes. The incidence increased progressively with age, particularly among individuals aged ≥80 years, with 4604 cases (22.92%). Regarding race/skin color, the majority of cases occurred among white individuals (81.8%), followed by brown individuals (15.4%) and black individuals (2.5%) [4]. Conclusions: Melanoma shows an uneven distribution in Brazil, possibly related to phenotypic risk factors and unequal access to specialized care. These findings underscore the need to reconsider strategies focused on prevention, early diagnosis, and health education, focusing on higher-risk groups [5].
