Twelve cases of epithelioid sarcoma have been reviewed, illustrating the diagnostic problems for which this rare tumor has become notorious and demonstrating varied rates of tumor progression. The histological features most helpful to the distinction of epithelioid sarcoma from other nodular skin lesions, including benign conditions such as rheumatoid nodule and granuloma annulare, are discussed. The ultrastructural appearances of two cases were similar to immature mesenchymal tissue.
回顾了12例上皮样肉瘤病例，阐明了这种罕见肿瘤恶名远扬的诊断难题，并展示了不同的肿瘤进展速率。讨论了对于将上皮样肉瘤与其他结节性皮肤病变（包括类风湿结节和环状肉芽肿等良性病变）相区分最有帮助的组织学特征。2例的超微结构表现类似于未成熟间充质组织。
