A primary extraskeletal osteosarcoma (EOS) is a rare tumour. An EOS of the seminal vesicle has not been reported in the literature. We describe a case of a seminal vesicle EOS initially detected as a pre-rectal mass on a routine transrectal ultrasound in a 48-year-old man. A computed tomography (CT) scan confirmed the tumour to be arising from the left seminal vesicle. A robot-assisted laparoscopic seminal vesiculectomy was performed to avoid neurovascular bundle injury. Microscopic examination of the resected specimen showed a poorly differentiated osteosarcoma originating from the seminal vesicle. The patient received adjuvant chemotherapy. He is doing well without voiding or erectile dysfunction and he is tumour-free five months after surgery.
原发性骨外骨肉瘤（EOS）是一种罕见的肿瘤。文献中尚未报道精囊的EOS。我们描述了一例精囊EOS病例，该病例最初是在一名48岁男性的常规经直肠超声检查中作为直肠前肿块被发现的。计算机断层扫描（CT）扫描证实肿瘤起源于左侧精囊。为避免神经血管束损伤，进行了机器人辅助腹腔镜精囊切除术。对切除标本的显微镜检查显示为起源于精囊的低分化骨肉瘤。患者接受了辅助化疗。他恢复良好，没有排尿或勃起功能障碍，术后五个月无肿瘤。
