Abstract：
Paratesticular leiomyosarcoma is a rare urologic cancer that arises from undifferentiated smooth muscles of the spermatic cord or epididymis. Few accounts of this cancer have been reported but previous reports have identified radiation and anabolic steroids as possible risk factors. We report a case of an 83-year-old man with a previous history of radiation therapy for prostate cancer, who presented with a painless left scrotal mass. Given the nonspecific presentation, a histopathological classification was warranted for a definitive diagnosis. The tumor was resected via simple orchiectomy and was diagnosed as a paratesticular grade III leiomyosarcoma without any further treatment. Patient had a follow-up CT scan of the abdomen and pelvis that was normal without metastasis. The patient\'s history of previous external beam radiation and now development of a secondary tumor sums to the few cases that have been previously reported with this association.
摘要：
睾丸旁平滑肌肉瘤是一种罕见的泌尿系癌症，起源于精索或附睾的未分化平滑肌。这种癌症的报道很少，但以前的报道已经确定辐射和合成代谢类固醇是可能的危险因素。我们报告了一个83岁的男性，有前列腺癌的放射治疗史，出现无痛的左阴囊肿块。鉴于非特定的演示，对于明确的诊断,需要进行组织病理学分类.通过简单的睾丸切除术切除肿瘤，并被诊断为睾丸旁III级平滑肌肉瘤，无需任何进一步治疗。患者的腹部和骨盆的随访CT扫描正常，无转移。患者的既往外照射史和现在继发肿瘤的发展总结为先前报道的少数病例。
