Cytomorphological Features of ALK-Positive Lung Adenocarcinomas: Psammoma Bodies and Signet Ring Cells

摘要

BACKGROUNDCorrelation between histology and genotype has been described in lung adenocarcinomas. For example, studies have demonstrated that adenocarcinomas with an anaplastic lymphoma kinase (ALK) gene rearrangement may have mucinous features. The objective of the current study was to determine whether a similar association can be identified in cytological specimens.
