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. Here we report a case of nonseminomatous GCT of the testis with a synchronous, symptomatic, solitary pubic bone metastasis that was completely controlled by systemic chemotherapy and locoregional radiation therapy. Solitary bone metastases from GCTs seem to be chemosensitive and radiosensitive, but we do not know their prognostic value. We reviewed the literature where 3 similar cases have been reported. We propose individualized management for symptomatic GCT patients including bone scintigraphy and/or PET examination at diagnosis and a combined cytotoxic approach with chemotherapy and radiation therapy.
