摘要

目的:探讨上皮样血管肉瘤(epithelioid angiosarcoma,EA)的临床病理学特征,诊断及鉴别诊断要点。方法:分析2010年1月至2019年12月期间蚌埠医学院第一附属医院收治的10例EA患者的临床诊疗资料,并行病理组织学形态和免疫组织化学特征观察分析。结果:在10例EA患者中,男8例,女2例,发生部位分别为颈部(2例)、胸壁(2例)、胰腺(1例)、会阴部(1例)、睾丸(1例)、臀部(1例)、足踝部(1例)、肋骨(1例)。在显微镜下,瘤细胞弥漫成片或聚集成巢状,瘤组织内可见大小不等的不规则血管样腔隙。瘤细胞具有上皮样特征,细胞体积大,呈圆形、梭形或多边形,细胞质丰富,呈嗜酸性,核仁明显。免疫表型示瘤细胞CD31、ERG均阳性,CD34和FLI-1大部分病例阳性。患者均行手术治疗,术后7例获得随访,随访时间2~60个月,6例死亡,1例疾病无进展生存。结论:EA是一种高度恶性的肿瘤,易误诊、漏诊,形态上与转移癌、上皮样血管内皮瘤、恶性黑色素瘤、上皮样肉瘤等具有一定的相似性,免疫组织化学检测有助于鉴别诊断。

Abstract

Objective: To explore the clinicopathological features, diagnosis, and differential diagnosis of epithelioid angiosarcoma (EA). Methods: The clinical diagnosis and treatment data of 10 EA patients admitted to First Affiliated Hospital of Bengbu Medical College from January 2010 to December 2019 were analyzed, and the histopathological morphology and immunohistochemical characteristics were observed and analyzed. Results: Of the 10 cases, 8 were male and 2 were female. The sites were neck (2 cases), chest wall (2 cases), pancreas (1 case), perineum (1 case), testicles (1 case), buttocks (1 case), ankles (1 case) and ribs (1 case). Microscopically, the tumor cells were diffused into sheets or clustered into nests, and irregular vascular-like Spaces of varying sizes were seen in the tumor tissue. Tumor cells have epithelioid characteristics, large cells, round, spindle or polygon, abundant cytoplasm eosinophilic, nucleoli obvious. Immunophenotype showed that CD31 and ERG were positive in tumor cells, and CD34 and FLI-1 were positive in most cases. All patients received surgical treatment, and 7 patients were followed up after surgery for 2–60 months. Six patients died and 1 patient survived without disease progression. Conclusion: EA is a highly malignant sarcoma, which is prone to misdiagnosis or missed diagnosis. It has certain morphological similarities with metastatic carcinoma, epithelioid hemangioendothelioma, malignant melanoma, and epithelioid sarcoma, Immunohistochemical tests are helpful in differentiating the diagnosis.

Keywords: angiosarcoma; epithelioid; immunohistochemistry; diagnosis; differential diagnosis
