Key result
Therapeutic irradiation for testicular seminoma is linked to paravertebral angiosarcoma 10 years after treatment.
Why the study?
Tumor induction by therapeutic irradiation after treatment for testicular seminoma remains a likely etiology for subsequent angiosarcoma, but other causes are possible.
Therapeutic irradiation for testicular seminoma may be associated with the development of secondary malignancies such as paravertebral angiosarcoma.
Alerts to rare radiation-associated sarcoma after seminoma; leaves open causal confirmation and surveillance needs in survivors.
We report a case of paravertebral angiosarcoma 10 years after treatment for testicular seminoma. The patient underwent irradiation treatment to areas including the mediastinum. Tumor induction by therapeutic irradiation remains the most likely etiology. Other possibilities include a natural association between seminoma and angiosarcoma, and perhaps the use of chemotherapy.
