摘要

Morphology of non-solid nodules samples obtained through CT-guided biopsy. Cell-block of CT-guided biopsy with neoplastic epithelial cell with secretive features, arranged in strains and micro-papillae (H&E, 100×). Adenocarcinoma of the lung with prevalent lepidic growth. Invasive features are focally present in the neoplasia (H&E, 100x)
