摘要

原发性肝脂肪肉瘤是一种极其罕见的源自脂肪细胞的恶性肿瘤，属于间充质肿瘤。我们介绍了一例 43 岁的西班牙裔男性患者，他患有多形性肝脂肪肉瘤，且没有 MDM2 基因扩增。术后两年零六个月，患者无任何症状。本病例是首例免疫组化检测 p16、p53、S100、波形蛋白阳性且无 MDM2 基因扩增的此类肿瘤。

Primary hepatic pleomorphic liposarcoma: Case report and literature review

Primary hepatic liposarcoma is an extremely rare malignant tumour derived from adipocytes and is part of the group of mesenchymal tumours. We present the case of a 43-year-old Hispanic male patient with a pleomorphic hepatic liposarcoma and absence of MDM2 gene amplification. Two years and six months after surgery, the patient is asymptomatic. The present case is the first report of this entity with positive immunohistochemical testing for p16, p53, S100, vimentin and absence of MDM2 gene amplification.
