A 42 year-old man presented with a localized germ cell tumor (GCT) of the left testicle in February 2010.
Serum tumor markers were normal. After orchiectomy the tumor was staged pT2 N0 M0 L0 V1 S0, clinical stage IB according to UICC criteria. Histopathological examination revealed seminoma and embryonal carcinoma, but no immature teratomatous components were present. Two cycles of adjuvant cisplatin-based chemotherapy were applied. Eighteen months later, he relapsed with enlarged thoracic and abdominal lymph nodes, malignant pleural effusion, liver metastases, and elevated LDH. A liver biopsy showed poorly differentiated carcinoma, which was positive for SALL4 as the only marker indicating a germ cell origin1.
