ABSTRACT

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of non-Hodgkin T-cell lymphoma, recently defined in the 2016 World Health Organization (WHO) classification of lymphoid neoplasms. It occurs more commonly when textured implants are used and appears clinically as a late seroma. Cytologically, these lesions are composed of large atypical cells with pleomorphic nucleus and an immunophenotype positive for T cell markers and CD30, and negative for ALK1. We report a 56-years-old woman with breast implants who developed a periprosthetic seroma three years after surgery. A fine needle aspiration of the lesion was carried out. Cytology and the immunocytochemical study revealed cells compatible with BIA-ALCL. The flow cytometric study was negative. Excisional biopsy of the capsule was performed, observing that the neoplastic cells were confined to the inner surface of the capsule. Imaging studies did not find evidence of disseminated disease. The present case demonstrates the importance of the study of any late periprosthetic effusion, which can be performed using fine needle aspiration.

ABSTRACT

O linfoma anaplásico de grandes células associado ao implante de mama (Breast Implant Associated Anaplastic Large Cell Lymphoma - BIA-ALCL) é uma doença maligna recentemente descoberta, rara e possivelmente associada aos implantes mamários texturizados. Essa revisão da literatura teve como objetivo trazer novas atualizações acerca da epidemiologia, fisiopatologia e fatores de risco para desenvolvimento do BIAALCL. Foi realizado o levantamento de dados do período de dezembro de 2018 a fevereiro de 2019, através das bases de dados PUBMED, LILACS e Scielo sendo selecionados 10 artigos publicados entre 2016 e 2018. Foi encontrada uma incidência variando entre 2,8:100.000 a 1:3 milhões de pacientes com implantes mamários. Os dados coletados corroboram para a teoria de que não há uma relação direta de causa e efeito entre os implantes mamários, mormente os texturizados, e o desenvolvimento do BIA-ALCL, podendo esses ser considerados somente como fatores de risco e não agentes causadores. A teoria fisiopatológica mais aceita é a de que os implantes mamários com maior área de superfície levariam a formação de maior biofilme por maior adesão bacteriana gerando inflamação crônica mais proeminente, levando ao gatilho para a transformação maligna das células T. As informações explicitadas nessa revisão devem auxiliar na ampliação de estudos acerca da doença e criação de políticas públicas para a prevenção e diagnóstico precoce de tal enfermidade. Pelos dados encontrados há necessidade de que cirurgiões plásticos realizem acompanhamento mais próximo de seus pacientes, assim como orientem os pacientes antes das cirurgias sobre a existência da doença.


Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a newly discovered and rare cancer possibly associated with textured breast implants. This literature review investigates its epidemiology, pathophysiology, and risk factors. PubMed, LILACS, and SciELO databases were searched from December 2018 to February 2019, and 10 articles published between 2016 and 2018 were selected. The incidence of BIA-ALCL ranged from 2.8:100,000 to 1:3 million breast implants. The obtained data corroborate the hypothesis that there is no direct cause and effect relationship between breast implants, especially textured implants, and BIA-ALCL, and these implants can be considered risk factors but not causative factors. The most accepted hypothesis on disease pathophysiology is that breast implants with larger surface areas may promote bacterial adhesion and biofilm formation, leading to severe chronic inflammation, triggering the malignant transformation of T cells. This review provides knowledge on BIA-ALCL and helps develop and implement public policies for disease prevention and timely diagnosis. The data highlight that long-term follow up is necessary and that surgeons should advise patients of the potential risk of developing BIA-ALCL before performing the implant surgery.

ABSTRACT

O linfoma anaplásico de células grandes (ALCL) associado a implantes mamários é um distúrbio linfoproliferativo das células T que foi recentemente reconhecido como uma entidade independente na classificação de linfomas da Organização Mundial de Saúde (OMS). Apesar do pequeno número de descrições, o número de casos está crescendo rapidamente. Das poucas centenas de casos que foram publicados até agora, muito poucos vieram do Brasil e nenhum foi relatado às autoridades locais. Encontramos um caso recentemente, e acreditamos que seu relato à comunidade local de cirurgia plástica poderá chamar a sua atenção para essa patologia emergente. O prognóstico é muito bom na maior parte dos casos diagnosticados. Contudo, ainda se sabe pouco sobre como e por que os implantes de silicone poderiam desencadear uma resposta linfoide, culminando num ALCL.


Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a T-cell lymphoproliferative disorder that has recently been recognized as an independent entity in the World Health Organization (WHO) classification of lymphomas. Despite the small number of reports to date, the number of cases is rapidly increasing. Of the few hundred cases that have been reported so far, very few came from Brazil and none have been reported to the local authorities. We encountered a case of BIA-ALCL and believe that its report to the local plastic surgery community could raise awareness to this emerging pathology. The prognosis is very good in most of the diagnosed cases. However, little is known about how and why silicone implants could trigger a lymphoid response that results in ALCL.
