Leiomyosarcoma of the scrotum, not involving the testis, epididymis, or spermatic cord, is a very rare type of tumor. A 36-year-old male presented with a slowly growing right scrotal mass (size: 3 × 2 cm). An ultrasound examination revealed a hypoechoic, subcutaneous, solid mass. Laboratory investigations detected normal levels of serum alpha-fetoprotein, beta-human chorionic gonadotropin, and lactate dehydrogenase. The mass was slowly growing and surgically resection was performed diagnosing leiomyosarcoma with histological examination. Wide local excision with a 2-cm margin around the operative scar and right orchiectomy were performed as second surgery. The patient has not suffered recurrence for 28 months.
阴囊平滑肌肉瘤，不累及睾丸、附睾或精索，是一种非常罕见的肿瘤类型。一名36岁男性患者出现右侧阴囊缓慢生长的肿块（大小：3×2厘米）。超声检查显示为低回声、皮下实性肿块。实验室检查发现血清甲胎蛋白、β-人绒毛膜促性腺激素和乳酸脱氢酶水平正常。肿块生长缓慢，通过手术切除并经组织学检查诊断为平滑肌肉瘤。第二次手术进行了在手术瘢痕周围2厘米切缘的广泛局部切除及右侧睾丸切除术。该患者28个月未复发。
