Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) in a young transgender woman: A case report.

[INTRODUCTION] Breast Implant-Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) is a rare T-cell lymphoma occurring after breast implant procedures. As gender confirmation therapy (GCT) in male-to-female transgender (FT), up to 60-70 % of patients require breast augmentation and are at risk for BIA-ALCL. Hence, we report the youngest BIA-ALCL case in the Italian population and the first early-stage BIA-ALCL occurred in FT patients.

[CASE PRESENTATION] A 27-years-old FT was admitted to outpatients' clinics due to swollen left breast. The patient underwent GCT with a macrotextured implant four years before. Clinical examination revealed swollen left breast. Ultrasound and magnetic resonance imaging confirmed left breast periprosthetic effusion. Positron emission tomography-computed tomography scan did not reveal any focal pathological uptake. Fine needle aspiration cytology confirmed BIA-ALCL suspect. The patient underwent bilateral en bloc breast implant removal and periprosthetic capsulectomy. Due to the early stage, adjuvant chemotherapy was omitted. Postoperative follow-up was unremarkable.

[CLINICAL DISCUSSION] BIA-ALCL is a rare, emergent clinical concern after breast implant surgery. GCT leads to improved body satisfaction and quality of life in FT individuals. As for non-trans patients undergoing breast reconstruction or breast augmentation, this clinical case once again demonstrates that FT patients undergoing breast implant surgery are at risk of BIA-ALCL.

[CONCLUSION] Physicians should promote awareness among patients' GCT and tailored postoperative follow-up.
