Abstract

In this article, we report a very rare case of secondary angiosarcoma in a young woman with no prior history of breast cancer who had bilateral prophylactic mastectomies with autologous reconstruction due to a strong family history of breast cancer and BRCA1 gene variant of uncertain significance. The surgery was complicated by recurrent fat necrosis requiring several excisions and additional reconstruction followed by the development of localized lymphedema and subsequent angiosarcoma in the reconstructed breast 10 years later. The angiosarcoma was high grade with prominent epithelioid features associated with abundant tumor-infiltrating lymphocytes. Amplification of C-MYC locus 8q21.24 was demonstrated by fluorescence in situ hybridization study. We postulate that chronic trauma from several surgeries including tissue hypoxia and impaired lymphatic drainage may have provided a milieu for angiogenesis and mutagenic transformation. Amplification of C-MYC locus 8q21.24 was most likely a strong oncogenic driver of angiosarcoma. To the best of our knowledge, this is the first report of its kind in the literature.
