OBJECTIVE
Sarcomas arising from the urinary tract are rare, representing less than 2% of all urologic tumors. The paratesticular region is one of the most unfrequent locations. Leiomyosarcoma, rhabdomyo-sarcoma, liposarcoma, malignant fibrohistiocytoma, etc. and the combination of two or more histological types has exceptionally been reported. We describe the case of a patient with a mixed paratesticular sarcoma and perform a bibliographic review.
METHODS
The patient underwent right radical orchyectomy and the surgical specimen was sent to pathologic study.
RESULTS
There are no previous case reports in the literature of paratesticular mixed tumor with liposarcoma and rhabdomyosarcoma.
CONCLUSIONS
Sarcomas of the spermatic cord are rare neoplasias and should be considered on the differential diagnosis of scrotal masses. The treatment of choice is surgical and adjuvant treatment must be individualized depending on tumor aggressiveness.
目的
起源于泌尿道的肉瘤很罕见，占所有泌尿系统肿瘤的比例不到2%。睾丸旁区域是最不常见的发病部位之一。平滑肌肉瘤、横纹肌肉瘤、脂肪肉瘤、恶性纤维组织细胞瘤等，以及两种或更多组织学类型的组合情况曾有过罕见报道。我们描述了一例睾丸旁混合性肉瘤患者的病例，并进行了文献回顾。
方法
患者接受了右侧根治性睾丸切除术，手术标本送去做病理研究。
结果
文献中此前尚无睾丸旁脂肪肉瘤与横纹肌肉瘤混合肿瘤的病例报告。
结论
精索肉瘤是罕见的肿瘤，在阴囊肿物的鉴别诊断中应予以考虑。首选治疗方法是手术，辅助治疗必须根据肿瘤的侵袭性进行个体化选择。
