Primary testicular sarcoma: a report of two cases

The clinical and pathologic features of two primary pure testicular sarcomas are reported. One tumor was an osteosarcoma and was found in a 30-year-old man; the other was a fibrosarcoma from an 86-year-old man. The patients were treated with orchiectomy and high ligation of the spermatic cord and received no postoperative therapy. Both of them were alive and well with no evidence of disease 6 months and 5 1/2 years, respectively, after orchiectomy. Most testicular sarcomas arise from a teratoma or, less commonly, originate from a spermatocytic seminoma, but our two cases and rare previously reported cases illustrate that pure sarcomas occur occasionally and may be associated with a favorable prognosis.
