We report on a 69 year-old patient with a leiomyoma of the seminal vesicle who presented with dysuria and pollakiuria. The rectal examination revealed a large, hard mass in an area corresponding to the seminal vesicle. The prostate was suspicious of malignancy, but transrectal needle biopsy specimens were negative. We managed the patient by prostatovesiculectomy. The pathological findings and the immunohistochemical staining pattern of smooth muscle with antibodies against beta-actin and desmin confirmed the diagnosis of a leiomyoma of the left seminal vesicle. To our knowledge, this kind of tumour is exceedingly rare, with only a few cases reported in the literature.
我们报告了一名69岁患有精囊平滑肌瘤的患者，其表现为排尿困难和尿频。直肠检查发现精囊对应区域有一个大的硬块。前列腺怀疑有恶性病变，但经直肠穿刺活检标本为阴性。我们对该患者进行了前列腺精囊切除术。病理检查结果以及用抗β-肌动蛋白和结蛋白抗体对平滑肌进行的免疫组化染色模式证实了左侧精囊平滑肌瘤的诊断。据我们所知，这种肿瘤极为罕见，文献中仅报道了少数病例。
