Endoscopic surgery has enabled performing multiple types of minimally invasive surgical approaches, including breast surgery. This technique is commonly used in Asian countries. Surgical options include single-port nipple and skin sparing surgery, which is reported to be oncologically safe and well tolerated. We present the first report in Peru on this surgical procedure in a patient with breast cancer treated with neoadjuvanttherapy, where we describe the surgical technique and the anatomopathological and aesthetic results.

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. Survival rate differences were assessed using the Log-rank test. Results: Overall, 584 patients were included (only trunk and extremities); 51% were male, the mean age was 61 (3–97) years, and 48% of patients resided in rural areas. The mean time to diagnosis was 22.6 months, and the mean Breslow thickness was 7.4 mm (T4). Lower extremity was the most common location (72%). A majority o...
