We present the case of a 60-year-old man who was referred with a 1-year history of a slow-growing right scrotal lump. Following surgical excision together with a radical orchidectomy, the histological diagnosis was of a paratesticular dedifferentiated liposarcoma. Radiological staging showed no metastatic disease. Six months later the patient presented with a new left scrotal lump, which was felt to be separate from the testis. Owing to the previous history of a liposarcoma and indeterminate ultrasound findings, this was surgically excised without orchidectomy. Histological analysis showed this to be an angiolipoma. The patient remained on clinical and radiological surveillance. Paratesticular tumours are rare neoplasms and liposarcomas of the spermatic cord only represent 7% of these lesions. Any link between lipomatous tumours and liposarcomas remains controversial and is still under investigation. This is the first case to report a paratesticular liposarcoma and a contralateral angiolipoma in the same patient.
我们报告一例60岁男性患者，因右侧阴囊缓慢生长的肿块就诊，病史1年。手术切除并进行根治性睾丸切除术后，组织学诊断为睾丸旁去分化脂肪肉瘤。影像学分期显示无转移病灶。6个月后，患者出现左侧阴囊新肿块，该肿块被认为与睾丸不相连。鉴于既往有脂肪肉瘤病史且超声检查结果不明确，此次未行睾丸切除，直接将肿块手术切除。组织学分析显示为血管脂肪瘤。患者继续接受临床和影像学监测。睾丸旁肿瘤是罕见的肿瘤，精索脂肪肉瘤仅占这些病变的7%。脂肪瘤性肿瘤与脂肪肉瘤之间的任何联系仍存在争议，仍在研究中。这是首例报告同一患者出现睾丸旁脂肪肉瘤和对侧血管脂肪瘤的病例。
