We describe the first case of a spindle cell/pleomorphic lipoma of the seminal vesicle. A 6.2cm large mass originating from the left seminal vesicle was incidentally detected on imaging for peripheral arterial disease. A transrectal ultrasound-guided biopsy was negative for malignancy. We proceeded with a robotic tumor resection due to the size of the mass and sarcomatoid features present on MR imaging. The final pathological work-up revealed a spindle cell/pleomorphic lipoma, immunohistochemical staining was performed with no malignant features detected, in particular no signs of an atypical lipomatous tumor. Ejaculatory function was preserved with reduced volume at 6-weeks follow-up.
我们报告首例精囊梭形细胞/多形性脂肪瘤病例。一名因外周动脉疾病行影像学检查时偶然发现起源于左侧精囊的一个6.2厘米大的肿块。经直肠超声引导下活检未发现恶性肿瘤。由于肿块大小及磁共振成像显示的肉瘤样特征，我们进行了机器人辅助肿瘤切除术。最终病理检查显示为梭形细胞/多形性脂肪瘤，免疫组化染色未发现恶性特征，尤其未发现非典型脂肪瘤性肿瘤的迹象。6周随访时射精功能得以保留，但其容量有所减少。
