title: Ossifying seminoma of the testis.
abstract: A 55-year-old Hispanic man presented with a large testicular mass with metastases to pelvic and retroperitoneal lymph nodes and bones. Computed tomographic scans revealed calcifications in the testis and lymph nodes. The orchiectomy specimen showed a seminoma with extensive ossifications. The amount of bone formation, believed to represent a degenerative phenomenon, is extremely unusual and, to the best of my knowledge, has not been presented in the literature.
