Male urethral sarcoma: a case report and literature review

Urethral tumors are rare and aggressive. They usually affect men (2:1) and occur more commonly in white (85% of cases). Soft tissue sarcomas are a heterogeneous group of tumors that arise from embryonic mesoderm. It represents 1% of all cases of urinary tract malignancies and rarely primary affect the ureter. We report a case of male urethral sarcoma. To date, only two similar cases have been published in literature.

尿道肿瘤（Urethral tumors）较为罕见且具有侵袭性。其好发于男性，男女患病比例约为2:1，且85%的病例发生于白种人群中。软组织肉瘤（Soft tissue sarcomas）是一类起源于胚胎中胚层的异质性肿瘤群，占所有泌尿系统恶性肿瘤（urinary tract malignancies）的1%，且极少原发于输尿管。本文报告1例男性尿道肉瘤病例，截至目前，全球仅在公开文献中报道过2例同类病例。
