Pulmonary small cell carcinoma in bronchial brushings shows small, hyperchromatic cells (about twice lymphocyte size) with scant cytoplasm, nuclear molding (where nuclei conform to each other's shapes), finely granular 'salt-and-pepper' chromatin, and inconspicuous nucleoli. The cells are fragile, leading to crush artifact (smudged nuclear material) and apoptotic debris. They may be arranged in loose clusters, linear streams, or singly. Bronchial brushings provide excellent cellular preservation and are highly sensitive for diagnosing small cell carcinoma due to direct sampling of visible lesions. Immunocytochemistry (synaptophysin, chromogranin, CD56) can confirm neuroendocrine differentiation.
