Liposarcoma of the spermatic cord is an extremely rare urological malignancy, with fewer than 300 cases reported in the literature worldwide, and it is often difficult to distinguish from inguinal hernias and epididymal cysts. Typically, it presents as an asymptomatic, slow-growing paratesticular mass.
The case described herein involves a 59-year-old man who presented to our hospital with a painless mass in the left scrotum. Physical examination revealed a fixed, firm mass in the left scrotum. Ultrasonography of the scrotum demonstrated an inhomogeneous echogenic mass measuring approximately 113 x 83 x 62 mm on the left side. Testicular MRI showed a mass in the left scrotum measuring approximately 67 x 56 x 98 mm, exhibiting isointence T1 mixed with high T2 signals. The patient then underwent surgery and pathology confirmed a liposarcoma of the spermatic cord. Currently no signs of tumor recurrence on follow-up.
Liposarcoma of the spermatic cord is an exceedingly rare condition, for which surgical intervention is the preferred treatment option. While there is no definitive evidence supporting the use of adjuvant radiotherapy following surgery, it remains necessary in cases where surgical margins are uncertain.
精索脂肪肉瘤是一种极为罕见的泌尿系统恶性肿瘤，全球文献报道的病例不足300例，且常难以与腹股沟疝和附睾囊肿相鉴别。通常，它表现为无症状、生长缓慢的睾丸旁肿块。
本文所述病例为一名59岁男性，因左侧阴囊无痛性肿块前来我院就诊。体格检查发现左侧阴囊有一个固定、质地坚硬的肿块。阴囊超声显示左侧有一个不均匀回声肿块，大小约为113×83×62毫米。睾丸磁共振成像显示左侧阴囊有一个大小约为67×56×98毫米的肿块，T1加权像呈等信号，T2加权像呈高信号。该患者随后接受了手术，病理证实为精索脂肪肉瘤。目前随访未发现肿瘤复发迹象。
精索脂肪肉瘤极为罕见，手术干预是首选的治疗方法。虽然没有确凿证据支持术后使用辅助放疗，但在手术切缘不确定的情况下仍有必要进行。
