轴外软组织脉络膜炎是罕见的。我们报告一位87岁男性，右手腕部轴外软组织脉络膜瘤，肿瘤很大，切面呈多结节状及黏液样。显微镜下，粘液样基质中可见上皮样细胞和梭形细胞巢。还观察到了凋亡细胞。免疫组化显示肿瘤细胞呈短尾及细胞角蛋白19弥漫阳性，提示肿瘤为轴外软组织脉络膜增生。轴外脉络膜是与Laskowski和Dabska提出的脉络膜周围（副脉络膜）相同的实体。(c)2011年Elsevier GmbH。All rights reserved.
Extra-axial soft tissue chordoma is rare. We report a case of extra-axial soft tissue chordoma of the right wrist in an 87-year-old man. The tumor was large, and the cut surface showed multinodular and myxoid appearance. Microscopically, nests of epithelioid and spindle cells were observed in the myxoid matrix. Vacuolated cells were also observed. The tumor cells were diffusely positive for brachyury and cytokeratin 19 on immunohistochemistry, suggesting that the tumor was extra-axial soft tissue chordoma. Extra-axial chordoma is the same entity as chordoma periphericum (parachordoma), as proposed by Laskowski and Dabska. (c) 2011 Elsevier GmbH. All rights reserved.
