Breast-implant-associated anaplastic large-cell lymphoma.

Breast-implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is an uncommon, recently recognized disease that seems to occur only in relation with implants with textured surfaces. Most cases present with late-onset peri-implant effusion or fluid collections that develop more than 12 months after insertion of the implant. The diagnosis is reached by cytological analysis of fluid samples obtained by ultrasound-guided fine-needle aspiration. These patients usually have a good prognosis after surgical removal of the implant. A small percentage of patients present with a nodule or mass adjacent to the implant that usually develops late. In these cases, the diagnosis is reached by the histological analysis of core-needle biopsy specimens. These patients have a worse prognosis and require a combination of surgery and systemic chemotherapy. The main immunophenotypic characteristics of this lymphoma are intense expression of CD30 and a lack of expression of anaplastic lymphoma kinase (ALK). Here we present a case of BIA-ALCL in a patient with implants with a textured surface that presented with peri-implant effusion and incipient formation of a millimetric nodule and was treated with removal of the implant and bilateral capsulectomy. It is important to point out that the disease requires multidisciplinary management and that the Spanish Agency of Medicines and Medical Devices (AEMPS) should be notified when the diagnosis is confirmed.
