Abstract:
Low-grade myofibroblastic sarcoma (LGMFS) is a rare type of sarcoma, and its manifestation as a radiotherapy (RT)-induced sarcoma following RT for breast cancer is even more unusual. To date, only one case of RT-induced mammary myofibroblastic sarcoma (MFS) has been reported. Here we present the case of a 49-year-old woman with LGMFS after undergoing breast-conserving surgery for invasive ductal carcinoma (IDC), and with a history of RT 16 years prior. Due to the rarity of this disease, previous studies have focused primarily on the pathological findings of MFS. In this report however, we present the clinical and radiological features of LGMFS in the retro pectoral area as a rare type of RT-induced sarcoma.
