Bronchiolar adenoma (BA) is a rare lung tumor that has recently been clearly named, including the previous ciliated muconodular papillary tumor (CMPT) and the so-called nonclassical CMPT. The most prominent histological feature of BA is a double-layer cell structure composed of a continuous basal cell layer and a luminal cell layer. BA lined purely by mucinous luminal cells is very rare, and only one case has been reported in the English literature. This type of BA can easily be misdiagnosed as early mucinous adenocarcinoma. This article analyzes the clinicopathological characteristics of a newly discovered case of BA lined purely by mucinous luminal cells and fully integrated with the literatures.
细支气管腺瘤（BA）是一种罕见的肺肿瘤，最近才被明确命名，包括之前的纤毛黏液结节状乳头状瘤（CMPT）和所谓的非典型CMPT。BA最显著的组织学特征是由连续的基底细胞层和管腔细胞层组成的双层细胞结构。纯由黏液性管腔细胞内衬的BA非常罕见，英文文献中仅报道过1例。这种类型的BA很容易被误诊为早期黏液腺癌。本文分析了1例新发现的纯由黏液性管腔细胞内衬的BA的临床病理特征，并结合文献进行全面分析。
