Epidemiology, clinical features, and outcomes of peripheral T-cell lymphoma in Latin America: an international, retrospective, cohort study.

Background: Peripheral T-cell lymphomas represent a rare and heterogeneous group of mature T-cell neoplasms characterised by aggressive behavior. Previous studies evaluating peripheral T-cell lymphoma epidemiology across Latin America have been restricted in their representation of most countries in the region. In this study, we aimed to describe peripheral T-cell lymphoma epidemiology across Latin America.
