细支气管—肺泡细胞癌属肺腺癌亚型。约占肺癌2.5％。本组16例,男:女为13∶3。年龄为36～63岁。半数为体检时发现肺部阴影。15例为孤立结节型,1例为弥漫型,肿瘤大小从2～15cm。右肺11例,左肺5例。组织学上肺泡型(10例),裂隙型(3例),乳头型(1例),粘液型(2例)。2例透射电镜观察见胞浆内有大量均质状电子密度增加颗粒和分泌泡,微绒毛突起。随访9例生存,7例死亡。
Bronchiolar-alveolar cell carcinoma is a lung adenocarcinoma subtype. About 2.5% of lung cancer. The group of 16 patients, male: female 13:3. Age is 36-63 years old. Half of the lungs were found to be shadowed during physical examination. 15 cases were solitary nodules and 1 case was diffuse. The tumor size ranged from 2 to 15 cm. There were 11 right lungs and 5 left lungs. Histologically alveolar type (10 cases), fissure type (3 cases), papillary type (1 case), mucinous type (2 cases). In 2 cases of transmission electron microscopy observations, there were a large number of homogenous electron density-increasing particles and secretory vesicles in the cytoplasm and microvillus protrusions. Nine patients survived and 7 patients died.
