Paratesticular Leiomyosarcoma Report of Two New Cases and Literature Review

High-frequency, real-time ultrasonography has an established role in the evaluation of scrotal masses.' Intratesticular or extratesticular location of masses can be difficult to determine by palpation alone. Sonography can also characterize lesions as fluid filled or solid. Recent studies of nontesticular intrascrotal masses suggest that a homogeneously echogenic sonographic appearance indicates a benign p r o c e~s .~,~ While extratesticular masses, which can arise from the epididymis, spermatic cord, or scrotal tunics, are usually benign,4 our recently encountered case of a pleomorphic myosarcoma is an exception. Its homogeneous echogenicity challenges the reliability of these sonographic criteria to exclude malignancy. CASE REPORTA 46-year-old black male was referred for ultrasound examination to evaluate a right scrotal mass that had been slowly enlarging over a period of one year. It was nontender and nonerythematous. No fever or leukocytosis was present. There was no history of trauma. On physical examination, a hard mass was palpated in the inferior right scrotum. The lesion did not transilluminate. Serum alpha-fetoprotein (AFP) and beta human chorionic gonadotropin were negative. The chest radiograph was normal.Hand-held real-time scrotal sonography, performed with a linear array 5.58-MHz transducer (Acuson-128, Mountain View, California), demonstrated a large, homogeneously echogenic From the
