We read with interest the article “Rare Cancer on the Rise: An Educational Review of Breast Implant-associated Anaplastic Large Cell Lymphoma,” published on June 26, 2020 (1). We want to congratulate the authors for an excellent review regarding the diagnosis, imaging findings, and management of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL).

Since 2017, we have started a study protocol to evaluate breast implants and their complications. And we agree with the authors that knowledge about BIA-ALCL etiology remains poorly understood, as there is a large variance in incidence in such cases. However, our group believes that through this letter, we can contribute two important points:

The SIGBIC consists of silicone-induced granuloma formation in the breast implant fibrous capsule without signs of implant rupture and without malignant cells on histology. We described the three breast MRI findings as (1) a black-drop sign, (2) a mass with hyperintense signal on T2, and (3) late contrast enhancement (2–5).
