We report a case of intraneural perineurioma, developed in the left cubital nerve, in a five-year old girl. This intraneural tumor is rare and shows a typical histologic appearance: concentric whorls of perineurial cells EMA+, PS100-, around nerve fibers. This tumor must be distinguished from extraneural or soft tissue perineurioma, also composed of perineurial cells, with distinct clinical presentation and histological appearance.
我们报告了一例发生在一名5岁女孩左侧尺神经的神经内神经束膜瘤。这种神经内肿瘤很罕见，具有典型的组织学表现：围绕神经纤维的神经束膜细胞呈EMA阳性、PS100阴性的同心性漩涡状排列。这种肿瘤必须与同样由神经束膜细胞组成的神经外或软组织神经束膜瘤相鉴别，它们具有不同的临床表现和组织学外观。
