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...

Summary: Breast-implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a non-Hodgkin lymphoma that arises in the space between the surface of a breast implant and the fibrous capsule that grows around the implant. Since its first description 20 years ago, almost 1000 cases of BIA-ALCL have been diagnosed worldwide. Nowadays, guidelines describe the diagnosis, staging, and treatment of this disease. We present the first two cases diagnosed and treated in Peru, demonstrating a wide range of aggressiveness of BIA-ALCL. © Plastic and Reconstructive Surgery - Global Open.All rights reserved.

Erosive adenomatosis is a rare benign neoplasm that affects the nipple. Characterized by erosion, telorrhoea, telorrhagia, nodularity, pruritus and erythema, causing a progressive destructive process of the nipple, which can be confused with Paget's disease; which is why knowledge of this pathology is essential to avoid surgical overtreatment. We present the case of a 35-year-old patient diagnosed and treated with surgery, as well as a review of the literature on this entity. © 2023
