A case report of BIA-ALCL: Diagnostic, treatment, and mammary reconstruction.

ABSTRACT

INTRODUCTION AND IMPORTANCE BIA-ALCL is a non-Hodgkin lymphoma occurring primarily in women with textured breast implants, typically presenting as late seroma. Diagnosis involves ultrasound-guided fine-needle aspiration or core needle biopsy, followed by cytologic and immunohistochemical evaluation. Positive results show CD30 cell expression and lack ALK expression. Treatment includes removing breast implants and the periprosthetic capsule. If the lymphoma has spread, en bloc capsulectomy, immunotherapy, and chemotherapy are required. Reconstruction can be done with smooth implants or autologous tissue. PRESENTATION OF CASE We present here the case of a woman with a 12-year history of microtextured breast implants, without any cancer family background, who presented with peri-implant effusion in the left breast, which tested positive for BIA-ALCL at stage IA. The patient underwent breast implant removal with total capsulectomy and posterior successful autologous tissue reconstruction, demonstrating that outcomes can be satisfactory when properly treated. CLINICAL DISCUSSION: Paying attention to signs in women with breast implants, beyond imaging tests, can aid in the early diagnosis of BIA-ALCL and ensure a not aggressive treatment. This approach allows the reconstruction with autologous tissue without the need of further implants. CONCLUSION: BIA-ALCL is a rare disease, further studies about this lymphoma can help with early diagnosis and potential prevention.
