Paratesticular liposarcomas are rare tumours which account for 12% of all liposarcomas. Probably there are about 186 cases which have been reported till date. They must be differentiated from tumours of testicular origin which have extension to the spermatic cord. We are reporting a case of a 50-year-old male who had presented with a painless swelling in the right hemiscrotum, which was of 20 years' duration. Inititally, a clinical diagnosis of testicular tumour was made; however, CT of the scrotum revealed paratesticular tumour? liposarcoma and testis being normal and displaced postero-inferiorly. Metastatic work-up, which included CT of the abdomen and pelvis, thorax and whole body scan, did not reveal any distant metastasis. Patient underwent high orchidectomy, hemiscrotectomy. Histopathological studies confirmed the diagnosis of well-differentiated liposarcoma (atypical lipomatous tumour of sclerosing type).
睾丸旁脂肪肉瘤是罕见肿瘤，占所有脂肪肉瘤的12%。迄今为止，可能已报道约186例病例。它们必须与起源于睾丸并延伸至精索的肿瘤相鉴别。我们报告一例50岁男性，其右侧阴囊出现无痛性肿胀，病程20年。最初临床诊断为睾丸肿瘤；然而，阴囊CT显示为睾丸旁肿瘤——脂肪肉瘤，睾丸正常且向后下移位。包括腹部和盆腔CT、胸部及全身扫描在内的转移灶检查未发现任何远处转移。患者接受了高位睾丸切除术及半阴囊切除术。组织病理学研究证实为高分化脂肪肉瘤（硬化型非典型脂肪瘤性肿瘤）。
