In 2016, the World Health Organization added Breast Implant-Associated Anaplastic Large Cell lymphoma as a provisionally recognized lymphoma to the family of existing Anaplastic Large Cell lymphomas. Current estimates of the lifetime risk of the disease in women with textured breast implants range from 1:1,000 to 1:30,000. The mean interval from implant placement to diagnosis is 10.7 ± 4.6 years and the most common clinical symptom at presentation is breast swelling. A high level of clinical suspicion is recommended in patients presenting with breast symptoms and/or peri-implant fluid collection occurring more than 1 year after breast implant placement. Ultrasound is the imaging modality of choice, with a high sensitivity for peri-implant fluid and a high specificity for peri-implant mass. When ultrasound is inconclusive, breast MRI is indicated. As of today, all confirmed cases have tested positive for CD30 immunohistochemistry and the disease has shown to have an excellent prognosis when it is diagnosed earlier (localized disease), and when complete surgery, consisting of explantation, capsulectomy, and removal of any associated capsule mass, is performed. This overview summarizes the available epidemiological and clinical data of Breast Implant-Associated Anaplastic Large Cell lymphoma, with an emphasis on imaging features.
