我们在此描述一个罕见的情况下，梭形细胞肿瘤发生在外耳道。一位38岁男性因左外耳道入口处进行性肿胀而就诊。病人接受了肿瘤切除手术。光镜下可见梭形细胞增生，胶原基质和鹿角状血管。肿瘤细胞呈波形蛋白和CD 34免疫化学阳性。该肿瘤随后被诊断为孤立性纤维瘤（SFT）。SFT最常发生在胸膜，并且被认为起源于中皮下结缔组织。虽然有数个胸膜外的SFT病例报告，但在文献中从未报道过发生在左外耳道入口处的SFT。作为一个基本上良性的肿瘤，它偶尔复发或转移后切除，因此，仔细随访是必要的。(C)2003年由Elsevier爱尔兰有限公司出版
We herein describe a rare case of a spindle-cell neoplasm arising in the external auditory canal. A 38-year-old man presented with a progressive swelling of the entrance of left external auditory meatus. The patient underwent a surgical removal of the tumor. A light microscopic study showed a spindle-cell proliferation with a collagenous stroma and a staghorn-like vascular pattern. The tumor cells were immunohistochemically positive for vimentin and CD34. The tumor was thereafter diagnosed to be a solitary fibrous tumor (SFT). SFTs most commonly occur in the pleura and are supposed to originate from submesothelial connective tissue. Although, several cases of extrapleural SFT have been reported, no SFT arising in the entrance of left external auditory canal have ever been reported in the literature. As a basically benign tumor, it occasionally relapses or metastasizes after excision, and therefore a careful follow up is necessary. (C) 2003 Published by Elsevier Ireland Ltd.
