Liposarcoma is a malignant neoplasm of the adipose tissue, and dedifferentiated liposarcoma is a relatively rare subtype. Liposarcomas are typically located in the lower extremities or retroperitoneum, but dedifferentiated liposarcoma of the spermatic cord is rare and no case of it with macroscopic ossification has been reported in the literature.
A male presented to our hospital with a painful, palpable, and hard left suprapubic mass, formed over 3 months. The mass was diagnosed as a spermatic cord tumor and was resected using high orchiectomy. Due to the histological diagnosis of dedifferentiated spermatic cord liposarcoma with ossification and positive margins, a second extended resection and adjuvant radiotherapy were performed.
To differentiate spermatic cord liposarcoma preoperatively is difficult. There is no gold standard treatment for it, although surgical complete resection with clear microscopic margins would be the most effective treatment.
脂肪肉瘤是一种脂肪组织的恶性肿瘤，去分化脂肪肉瘤是一种相对罕见的亚型。脂肪肉瘤通常位于下肢或腹膜后，但精索去分化脂肪肉瘤罕见，且文献中未报道过伴有肉眼可见骨化的病例。
一名男性因左耻骨上区出现疼痛、可触及的硬块3个月就诊于我院。该肿块被诊断为精索肿瘤，并通过高位睾丸切除术切除。由于组织学诊断为伴有骨化的精索去分化脂肪肉瘤且切缘阳性，遂进行了二次扩大切除术及辅助放疗。
术前鉴别精索脂肪肉瘤困难。目前尚无针对该病的金标准治疗方法，尽管手术切缘显微镜下清晰完整切除是最有效的治疗方法。
