【摘要】 目的:探讨肺乳头状腺瘤的临床病理特点。方法:应用光镜、免疫组化染色等方法对我院一例肺乳头状腺瘤进行分析,并复习文献。结果:肿瘤为分化成熟的肺泡上皮细胞构成腺管,由乳头状、团块状结构及纤维间质构成。腺管和乳头上皮多为单层排列,细胞呈立方状,核淡染,无核分裂。免疫组化示瘤细胞CK(++),TTF-1(++),间质V im entin(++),Actin(+)。结论:肺乳头状腺瘤是一种罕见的良性肿瘤,易与硬化性血管瘤、肺泡性腺瘤、乳头状腺癌混淆。更多还原

【Abstract】 Objective:To investigate the clinicopathology features of papillary adenoma of the lung.Method:Morpholoical observation and immunohistochemistry was applied for one case of papillary adenoma of the lung,and the literatures were also reviewed.Results:The malignant cells were arranged in papillary and adenoma with the well differentiated pulmonary alveolus epithelium,cells grew with a line,the surface cells were cubic,nucles were normally stained and caryokinesis were invisible.Immunohistochemically,the tumor cells were positive for CK and TTF-1,storomal were positive for Vimentin and Actin.Conclusions:Papillary adenoma of the lung is a rare tumor,which is easy to be confused with sclerosing and alveolar adenoma and papillary carcinoma.更多还原
