嗜酸细胞性筋膜炎 Eosinophilic Fasciifis(EF),是近年来新认识的一种结缔组织疾病。自1974年 Shulman 首先报导以来,国际文献已陆续报导了100多例,国内亦报导了25例,大多数作者认为 EF 是一个独立的疾病,并强调深筋膜改变是唯一的病理基础。本文对 EF 标本进行观察,并辅以正常人肌肉标本进行对照,目的在于①了解正常人深筋膜和肌衣在光镜下的分布特点。②弄清 EF 的确切病变部位。 Eosinophilic fasciitis Eosinophilic Fasciifis (EF), a newly recognized connective tissue disease in recent years. Since Shulman first reported in 1974, more than 100 cases have been reported in international literature and 25 cases reported in China. Most authors consider EF as an independent disease and emphasize that deep fascia changes are the only pathological basis. In this paper, EF specimens were observed and supplemented with normal human muscle specimens for control, the purpose is to ① understand the normal deep fascia and muscle clothing under light microscopy distribution. ② clarify the exact location of EF lesions.
