食管梭形细胞鳞状细胞癌占食管癌的2.4%,1904年由Ｈａｎｓｅｍａｎｎ首先描述,曾用过假肉瘤、癌肉瘤、假肉瘤样癌等多种名称。近年来随着电镜及免疫组化方面的研究,支持了这类肿瘤上皮源性的假设,目前归于食管鳞状细胞癌(ＳＣＣ)的一个特殊亚型。作者用Ｋｉ67及图象分析仪研究
Esophageal spindle cell squamous cell carcinoma accounts for 2.4% of esophageal cancer, first described by Hansemann in 1904, and pseudomyosarcomas, carcinosarcomas, pseudosarcoid carcinomas, and other names have been used. In recent years, with the study of electron microscopy and immunohistochemistry to support the hypothesis of epithelial origin of such tumors, now attributed to a special subtype of esophageal squamous cell carcinoma (SCC).
