case_images: Metastatic classic seminoma was verified through pathologic investigation and IHC (Figure 2).
case_images: A chest-abdominal and pelvis CT in coronal view (a) and axial view (b) showing a residual mass of about 11 x 7 x 4 cm with a partial response to radiotherapy, without distant metastasis.
