Objective: To describe the characteristics of male breast cancer in patients treated at Clínica Alemana de Santiago and to relate the observed reality with the available evidence. Materials and Methods: A retrospective descriptive study. All male patients treated for breast cancer at our center between January 2014 and April 2024 were included. Data were collected from the institution’s authorized REDcap database. Results: Ten patients met the search criteria. The main reason for consultation was a retroareolar nodule. All patients underwent mammography and breast ultrasound. The majority of cases were diagnosed at stages 0, I, and II (80%), although one case of metastatic disease was observed. The most common type was invasive ductal carcinoma of the luminal B subtype (80%). Nine patients underwent therapy with curative intent, and most underwent total mastectomy with sentinel lymph node biopsy. Seven patients received adjuvant hormone therapy, three received radiotherapy, and four received chemotherapy. Dis-cussion: In our series, some advanced-stage cases were noted, contrasting with European and American series, reflecting lower awareness in the region. We also observed a deficit in conducting recommended genetic studies. Treatment follows guidelines used in women, but key differences must be considered. Conclusion: Given the lack of large studies in Latin America, case series like this help study this patholo-gy in our population. Concordance with international studies was observed, but it is essential to increase awareness and improve access to genetic testing.
