食管鳞状细胞乳头状瘤的检出率有所增加,但其仍被视为少见病变。其发病机理和恶变倾向尚不明了。本文旨在通过结合临床与病理检查结果及随访观察资料来阐明这些问题。 材料与方法:受试者为1970至1993年间空军病理研究所诊断为食管鳞状细胞乳头状瘤的患者。同时期全部食管病例用作对照研究。每个病例均作切片HE染色,对个别病例还作加或不加淀粉酶预消化的过碘酸-希夫染色检查。本研究将突起于粘膜表面、衍生于固有层、覆盖在指样隆起的增生性鳞状上皮细胞定
The detection rate of esophageal squamous cell papilloma has increased, but it is still regarded as a rare lesion. The pathogenesis and malignant tendency are still unknown. This article aims to clarify these issues by combining clinical and pathological findings and follow-up observations. Materials and Methods: Subjects were diagnosed with esophageal squamous cell papilloma from the Air Force Pathology Institute from 1970 to 1993. All esophageal cases were used as controlled studies during the same period. Each case was sectioned for HE staining, and individual cases were also checked for periodic acid-Schiff staining with or without amylase pre-digestion. This study will focus on the mucosal surface, derived from the lamina propria, and covered with hyperplasia squamous epithelium
