BACKGROUND
Adenoma of the esophagus is a rare type of esophageal submucosal tumor.
METHODS
An immunohistochemical and histopathologic study is reported of specimen from a patient with adenoma of the esophagus.
RESULTS
The eighth reported case of esophageal submucosal adenoma without Barrett epithelium is described. The patient was a 58-year-old man with an adenoma and carcinoma of the esophagus. The adenoma showed papillotubular structures lined with two layers of cuboidal cells within the submucosa and lamina muscularis mucosae, and the carcinoma was of the superficial squamous cell type confined to the submucosa.
CONCLUSIONS
Morphologic findings suggested that this adenoma had originated from the duct of the esophageal gland proper.
背景
食管腺瘤是一种罕见的食管黏膜下肿瘤。
方法
报告了一例食管腺瘤患者标本的免疫组织化学和组织病理学研究。
结果
描述了第八例无巴雷特上皮的食管黏膜下腺瘤。患者为一名58岁男性，患有食管腺瘤和癌。腺瘤表现为乳头管状结构，由黏膜下层和黏膜肌层内的两层立方细胞构成，而癌为局限于黏膜下层的浅表鳞状细胞型。
结论
形态学表现提示该腺瘤起源于食管固有腺管。
