细支气管肺泡细胞癌是一种少见的特殊型原发性肺腺癌。作者等曾通过手术及尸检材料结合临床随访观察对本病的病理形态学改变及病理类型与予后的关系等问题作了报告。本文在上述研究的基础上,观察了本癌的细胞超微结构变化,并结合这种变化的特点,探讨本癌的细胞起源,报告如下: Bronchioloalveolar cell carcinoma is a rare type of primary lung adenocarcinoma. The authors reported on the pathological and pathological changes of the disease and the relationship between the pathological type and the post-mortem. Based on the above studies, this article observed the ultrastructural changes of the cell and combined the characteristics of this change to explore the cell origin of this cancer. The report is as follows:
