Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare primary malignancy of the breast that has garnered significant attention in recent years. The disease was recognized as a distinct entity in 2016, and evidence-based guidelines for diagnosis and management have since been established. The classic presentation of BIA-ALCL is the spontaneous development of a periprosthetic fluid collection at least one year after breast implant placement. All reported cases have involved textured implants. While most cases are indolent with an excellent prognosis, some are more aggressive and may involve regional nodal or distant metastases.
A 62-year-old female with a history of cosmetic augmentation mammaplasty and prior BIA-ALCL of the right breast presented to the plastic surgery clinic with several months of increasing right breast fullness and discomfort. She had markedly asymmetric breasts but no palpable masses or lymphadenopathy. Diagnostic mammography and targeted right breast ultrasound raised concern for implant-associated malignancy. Given the patient's history of breast lymphoma, concerning physical examination and the available imaging, the patient was taken to the operating room for bilateral breast implant removal via en bloc capsulectomy. The procedure was performed within ten days of the initial consultation. Gross intraoperative examination of the right breast capsule was concerning for malignancy. Microscopic evaluation of the capsule and periprosthetic fluid specimens confirmed the presence of BIA-ALCL associated with the removed right breast implant.
This case highlights the importance of a multidisciplinary approach to diagnosing and treating BIA-ALCL as protocols evolve. While it may be most common for the plastic surgeon to field questions and concerns about BIA-ALCL, patients often initially present to other specialists, such as surgical oncologists and primary care physicians. Clinicians across specialties need to be educated on the current knowledge regarding BIA-ALCL to provide the best possible care for these patients.

A 62-year-old female with a history of cosmetic augmentation mammaplasty and prior breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) of the right breast presented to the plastic surgery clinic with several months of increasing right breast fullness and discomfort. She underwent elective augmentation mammoplasty in 1985 with the placement of a textured saline implant on the right and a smooth saline implant on the left as part of a comparative trial. She was diagnosed with ALCL of the right breast in January 2009, confirmed by a pericapsular solid mass biopsy. She underwent chemotherapy, and the implants were retained. Post-chemotherapy PET/CT scans were negative, and the patient was followed by medical oncology at least annually. Routine mammography in 2018 noted concern for right implant rupture with extravasated, non-resorbed saline within the capsule. The patient was then hospitalized in 2019 for right-sided chest pain and shortness of breath; a chest CT scan obtained at that time showed, again, a collapsed right breast implant with a large surrounding fluid collection suggesting intracapsular rupture, for which the patient was referred to a plastic surgery clinic.
On initial presentation, the patient had markedly asymmetric breasts (Figure 1). There were no palpable masses or lymphadenopathy. Diagnostic mammography and targeted right breast ultrasound raised concern for implant-associated malignancy, with no discrete mass visualized. Given the patient's history of breast lymphoma, concerning physical examination and the available imaging, the patient was taken to the operating room for bilateral breast implant removal via en bloc capsulectomy, defined as gross removal of the entire implant contained within the capsule without performing a capsulotomy. The procedure was performed within ten days of the initial consultation.

Inframammary incisions were made, and en bloc resection was completed bilaterally (Figure 2A). Both implants were in the subglandular plane. The left implant was smooth and saline-filled; the right implant was textured. The left periprosthetic capsule appeared grossly normal with no intracapsular fluid or evidence of thickening or nodules (Figure 2B). In stark contrast, the right capsule was markedly thickened, with yellowish periprosthetic fluid and white caseous material within the capsule without discrete tumor nodules (Figures 2C and 2D). Both surgical sites were thoroughly irrigated prior to closure, and the patient had an uncomplicated postoperative course.

On microscopic examination of the right capsule (Figure 3), there was a thick layer of fibrinonecrotic material on the luminal side of the capsule, corresponding to the gross caseous material. Within the fibrin was extensive tumor necrosis and ghosts of lymphoma cells, with small pockets of preserved large lymphoma cells. Immunohistochemistry showed the neoplastic cells to be positive for CD30, CD4, epithelial membrane antigen, TIA-1, and CD43. The left implant capsule had only reactive changes and no morphologic evidence of lymphoma.

The patient continues to follow regularly with both plastic surgery and medical oncology, and she is doing well. Postoperative PET/CT scans have shown no evidence of local or regional lymph node spread. Unfortunately, due to the chronic seroma with increasing size, there is a significant deflation deformity of the right breast (Figure 4), and she is considering autologous-based reconstruction.

BIA-ALCL is a rare primary malignancy of the breast that has garnered significant attention in recent years. The disease was first described in 1997,1 with the US Food and Drug Administration releasing a warning statement in 20112 and the World Health Organization recognizing the disease as a distinct entity in 2016.3 The National Comprehensive Cancer Network has since established evidence-based guidelines for diagnosis and management.4
The classic presentation of BIA-ALCL is the spontaneous development of a periprosthetic fluid collection at least one year after implant placement. All reported cases have involved textured implants,5 without significant risk differences between silicone- and saline-filled implants.6 Pathologic evaluation of periprosthetic fluid shows a monoclonal proliferation of CD30+ and anaplastic lymphoma kinase-negative T-cells.7 Although the pathogenesis is not yet fully understood, it is generally believed to involve a chronic inflammatory response leading to T-cell dysplasia in patients with genetic susceptibility.7,8 The standard of care for confirmed cases is the removal of the affected implant via en bloc capsulectomy.4 While most cases are indolent with an excellent prognosis, some are more aggressive and may involve regional nodal or distant metastases.9
This case report highlights a unique presentation of BIA-ALCL in a patient with one textured implant and one smooth implant. To the authors' knowledge, no studies to date report "split breast" trials to investigate the incidence of BIA-ALCL in textured versus smooth implants in the same patient. Such a study would be unethical, given the now-known relationship between textured implants and ALCL. However, similar studies have been performed to evaluate capsular contracture formation. In double-blind prospective trials in which patients received one textured and one smooth silicone gel implant, the textured implants were found to be protective against capsular contracture.10,11
The patient received her cosmetic breast augmentation free of charge by enrolling in a study similar to the aforementioned split-breast studies. The patient subsequently developed BIA-ALCL on the side of the textured implant. To the authors' knowledge, this unique presentation has not been described in the literature and emphasizes the increased risk associated with textured implants and the importance of surveillance.
This case is also an unfortunate example of a delay in treatment. Although pathology reports in 2009 showed ALCL, a delay in implant removal and capsulectomy was likely due to both a discontinuity of care and a lack of established guidelines for BIA-ALCL management. This highlights the importance of a multidisciplinary approach to diagnosing and treating BIA-ALCL as protocols continue to evolve. The current recommendation for resectable disease is complete excision by total capsulectomy and implant removal; at this time, sentinel lymph node biopsy is not a part of the treatment algorithm.12 Multidisciplinary care is important for all cases, particularly those with unresectable disease or cases that may benefit from additional therapy aside from surgery.12 While it may be most common for the plastic surgeon to field questions and concerns about BIA-ALCL, patients often initially present to other specialists, such as surgical oncologists or primary care physicians. Clinicians across specialties need to be educated on the current knowledge regarding BIA-ALCL in order to provide the best possible care for these patients.
BIA-ALCL is a primary malignancy of the breast associated with textured breast implants that has garnered attention in recent years, both within the medical and surgical communities as well as the popular media. Most cases are indolent and are associated with good outcomes, but the disease may progress to involve local and regional lymph nodes or distant metastases. This case highlights the importance of a multidisciplinary approach to diagnosing and treating BIA-ALCL. Patients often initially present to specialists such as surgical oncologists, as well as to primary care physicians. Thus, it is paramount for clinicians, particularly surgeons, to be educated on the current knowledge regarding BIA-ALCL and its presentation to promote appropriate surveillance and guide therapy.
BIA-ALCL is a primary malignancy of the breast that is not yet fully understood. All reported cases of BIA-ALCL have been associated with the use of textured breast implants. Surgeons, as well as primary care and other physicians, should be aware of BIA-ALCL and its presentation in patients with breast implants.
