Obtaining diagnostic material from small pulmonary lesions remains a persistent barrier to early-stage lung cancer diagnosis. Contemporary diagnostic pathways increasingly rely on bronchoscopy techniques and computed tomography (CT)-guided transthoracic needle sampling; however, limited cellularity, obscuring blood, variable smear thickness and other artifacts can compromise both rapid on-site evaluation (ROSE) and downstream classification. This manuscript describes a rapid, ethanol-based liquid preparation that is intended to standardize slide cellular distribution, reduce obscuring background, and generate two complementary cytology slides from minimal sample volume. Immediately after sample acquisition, one to three drops of aspirate or collected material are introduced into a 10 mL ethanol-based preservation vial. Using an F50 filtration device, half of the preserved suspension is processed onto a first slide; the slide is removed approximately 20 seconds after initiation and immediately stained with Diff-Quik or a rapid Papanicolaou (PAP) variant to support ROSE. The remaining suspension is processed in the same manner onto a second slide, which is placed directly into ethanol for subsequent PAP staining and further evaluation. Representative images demonstrate preservation of diagnostic cytomorphology across benign, reactive, and malignant lung cytology categories, including lymphocyte-rich inflammatory backgrounds, macrophage-predominant specimens, atypical epithelial populations, squamous cell carcinoma, and metastatic carcinoma. The workflow is designed to reduce preparation-to-preparation variability and to provide consistent, interpretable slides in settings where tissue acquisition is challenging and time is constrained. Future prospective studies should quantify adequacy, diagnostic concordance, and suitability for ancillary testing within standardized lung cytopathology reporting frameworks.
