Abstract
Extraosseous osteosarcoma (EOO) is a rare mesenchymal malignancy representing 4% of all osteosarcomas and 1% of soft tissue sarcomas. The testes, its supporting structures, that is, paratestes, and the spermatic cord are among the rarest sites for EOO, with only 11 published English language reports to date. We report our experience with a 73-year-old male presenting with left hemiscrotal swelling, noted to have extensive amorphous intratumoral calcification on imaging. He underwent left high inguinal orchidectomy with en bloc hemiscrotectomy, with a final pathologic diagnosis of primary paratesticular osteosarcoma. Our literature review corroborates this distinctive, hitherto overlooked imaging feature.
