摘要
食管表皮样化生又称食管角化症,是一种罕见的病症,其发病机制尚不明确,缺乏特征性临床表现,内镜下主要表现为黏膜白斑,病理特征显示增生上皮、突出的颗粒细胞层和局部角化不全症。迄今为止,国内外发表有关食管表皮样化生的研究文献甚少,现就食管表皮样化生的流行病学、临床特征及相关鉴别诊断作一综述。
Esophageal epidermoid metaplasia, also known as esophageal keratosis,is a rare disease. Its pathogenesis is still unclear and lacks characteristic clinical manifestations. Endoscopic manifestations are mainly mucosal leukoplakia.Pathological features show proliferative epithelium, prominent granular cell layer and local keratosis imperfecta. Up to now,few literatures have been published on esophageal epidermoid metaplasia at home and abroad. This article reviews the epidemiology,clinical features and differential diagnosis of esophageal epidermoid metaplasia.
