Sclerosing variant of well-differentiated testicular liposarcoma: a case report

ABSTRACT Testicular cancers are classified in germ cell and non-germ cell tumors, as well as, liposarcomas. We report the case of a patient with a large testicular liposarcoma, submitted to surgical treatment with excision of scrotal pouch and segment of the spermatic cord, and the left testicle, showing a good evolution. This report presents one of the first cases of a sclerosing variant of well-differentiated testicular liposarcoma, large in size and with no association with another cancer. Due to their location, the diagnosis is difficult and unusual. Complete tumor resection and regular medical follow-up show a good prognosis, less recurrence, and little cellular differentiation.摘要：睾丸癌（Testicular cancers）可分为生殖细胞肿瘤（germ cell tumors）、非生殖细胞肿瘤（non-germ cell tumors）及脂肪肉瘤（liposarcomas）三类。本研究报告1例巨大睾丸脂肪肉瘤患者，该患者接受阴囊囊（scrotal pouch）、精索（spermatic cord）节段及左侧睾丸（left testicle）切除术治疗，术后恢复良好。本次报道为首批伴硬化亚型（sclerosing variant）的高分化（well-differentiated）睾丸脂肪肉瘤病例之一，该肿瘤体积巨大且未合并其他恶性肿瘤。由于该肿瘤发病部位特殊，临床诊断颇具难度且较为罕见。完整切除肿瘤（Complete tumor resection）并辅以规律医学随访（regular medical follow-up）可获得良好预后（prognosis），复发（recurrence）率较低，且肿瘤细胞分化程度良好。
