Primary cytodiagnosis of dually differentiated lung cancer by transthoracic fine needle aspiration.
The cytologic features are described in a case of squamous cell carcinoma and small cell cancer of the lung concurrently diagnosed by a single transthoracic fine needle aspiration specimen. The value of diagnostic cytology in the detection of dually differentiated lung malignancies is discussed, and the importance of identifying the small cell component in order to direct appropriate therapy is emphasized.
