Breast implant anaplastic large cell lymphoma (ALCL) is a T-cell neoplasm arising around textured breast implants. Our host discusses with Drs. Medeiros and Miranda their recent report on eight cases of Epstein–Barr virus (EBV)-positive large B-cell lymphoma associated with breast implants. Their data suggest a pathogenetic role for breast implants (as well as EBV) in the pathogenesis of this type of implant-associated lymphomas. Study by Medeiros and Miranda et al. Epstein–Barr-virus-positive large B-cell lymphoma associated with breast implants: an analysis of eight patients suggesting a possible pathogenetic relationship. Modern Pathology, 34, 2154–2167.
