MYC Amplification in Epithelioid Angiosarcoma of the Urinary Bladder and Prostate Following Prostate Radiotherapy: A Case Report with a Novel Molecular Alteration
Epithelioid angiosarcoma is a rare variant of angiosarcoma. Radiation-associated epithelioid angiosarcoma of the urinary bladder and prostate is an exceedingly rare tumor and there are only 8 cases of epithelioid angiosarcoma of the urinary bladder and prostate associated with previous radiotherapy in the literature. To the best of our knowledge, MYC gene amplification has not been previously reported in epithelioid angiosarcoma of the urinary bladder and prostate following radiotherapy, although it is observed in radiation-associated angiosarcoma of other anatomic sites. Here we report the first case of epithelioid angiosarcoma of the urinary bladder and prostate with MYC gene amplification detected by fluorescence in situ hybridization (FISH) analysis in a 70-year-old male patient 10 years after receiving radiation and hormonal therapy for prostate cancer.
