Bronchioloalveolar carcinoma is classified as a subset of lung adenocarcinoma, but has a distinct clinical presentation, tumor biology, and favorable prognosis.
细支气管肺泡癌虽被归为肺腺癌的一个亚型,但它有自己独特的临床表现、肿瘤生物学特征和预后。

Results72 cases of bronchioloalveolar carcinoma of the CT findings, can be broadly classified into three types: Type isolated lesions, accounting for 75% (54/72);
结果从72例细支气管肺泡癌的CT表现,大致可分为以下三型:孤立病灶型,占75%(54/72);
细支气管肺泡癌是肺腺癌的一个特殊亚型,约占整个非小细胞肺癌的3% ~ 30%。与其他非小细胞肺癌的亚型相比,细支气管肺泡癌具有独特的临床表现、组织生物学行为、流行病学特点及特殊的治疗反应及预后。随着人们认识的不断深入,此概念逐渐明确完善。直到1999年,世界卫生组织将细支气管肺泡癌严格定义为:沿着肺泡结构鳞片状扩散,没有基质、血管和胸膜侵犯的肺癌,即单纯的细支气管肺泡癌。此定义一直沿用至今。在实际病例中,细支气管肺泡癌常与其他类型的腺癌成分混合存在。
