====== Residual masses after radiotherapy for seminoma ======

* '''Patients should undergo biopsy and histologic confirmation of the suspected lesion before management decisions are made.'''
** '''Although rare, seminoma may transform into NSGCT elements, and this should be considered in patients with metastatic seminoma who fail to respond to conventional therapy.'''
** Either an open or a robotic/laparoscopic biopsy of the para-aortic mass is an acceptable approach if CT-guided biopsy is not feasible or the result is non-diagnostic.
** RPLND should not be performed without histologic confirmation of NSGCT pathology.
