Primary testicular osteosarcoma

Abstract

Primary testicular osteosarcoma is an extremely rare type of malignant tumor, and to our knowledge, only two other cases have previously been reported in the medical literature. A 63-year-old man, who presented with a large painless left inguinal and scrotal mass, underwent radical orchiectomy. Pathological examination was suggestive of testiscular osteosarcoma. The patient received no adjuvant therapy and after 12months of follow-up, the patient remains free of disease.
