An Unexpected Late Recurrence of Breast Irradiation-Induced Angiosarcoma Following Autologous Microvascular Breast Reconstruction

Abstract

The authors present the case of a 68-year-old female who developed recurrent angiosarcoma, a rare but recognized complication after breast irradiation therapy in the treatment of breast cancer. Microvascular breast reconstruction was performed after the completion of 10 years of disease-free clinical surveillance. Abdominal tissue was harvested and transferred onto the chest wall with restoration of its blood supply using microsurgical techniques to recreate the breast. Unexpectedly, local recurrence of irradiation-induced angiosarcoma was confirmed in the reconstructed breast 12 years later, a unique finding, given the long latent period and recruitment of tissues from a distant site. It is vital to consider the potential of late recurrence before embarking on complex reconstructions, and this should be discussed with patients who have a history of angiosarcoma. This further emphasizes the importance of long-term surveillance in such a rare, yet aggressive tumor at specialist centers.
