Mammography, ultrasound, and MRI revealed a periprosthetic fluid collection and mass-like enhancement on the left breast at the 4 o'clock region showing sustained peripheral enhancement (Figure 1).
Macroscopy examination: (a) right breast capsulectomy with a mass of 47 g and (b) left breast capsulectomy and implant 294 g.

The PCR product was electrophoresed with the Bio Rad  system. The PCR showed monoclonal bands (Figure 4). The following abnormalities were detected: A-Vbeta+Jbeta1+Jbeta2 regions TCRB; B-VB+Jbeta2 regions TCRB; C-Dbeta+Jbeta1+Jbeta2 regions TCRB; A-Vdelta1-8, Vdelta10, + multiple Jdelta regions TCRG; and B-Vdelta9, Vdelta11+multiple Jdelta regions TCRG.
