Presentation of nonseminomatous germ cell tumor of the testis with symptomatic solitary bone metastasis. A case report with review of the literature.

Metastatic bone lesions are exceptional at diagnosis in germ cell tumors (GCTs). Bone involvement is usually a late event combined with synchronous metastasis in the retroperitoneal lymph nodes, lung and liver. Bone examination is not considered a standard procedure in the staging of GCTs, and this may contribute to underestimation of the real proportion of bone metastases.
