The histological study of a painful cutaneous nodule located in the interscapular region, which had been present for 20 years in a 59-year old male patient has show typical features of dermal myxoma of the nerve sheaths. This was a lobulated myxomatous tumour with fusiform and dendritic cells plus a few epithelioid and multinucleate cells. Immunostaining was positive for the S100 protein and negative for factor XIIIa and EMA. These data suggest that this tumour was of schwannian origin.
对一名59岁男性患者肩胛间区出现20年的疼痛性皮肤结节进行组织学研究，结果显示为神经鞘膜真皮黏液瘤的典型特征。这是一个分叶状黏液瘤性肿瘤，含有梭形细胞和树枝状细胞，以及少数上皮样细胞和多核细胞。免疫染色显示S100蛋白呈阳性，而因子ⅩⅢa和上皮膜抗原呈阴性。这些数据表明该肿瘤起源于施万细胞。
