Inflammatory changes related to active tuberculosis: confusion with oat cell carcinoma of the lung on cytology specimens.
One case of small cell lung carcinoma diagnosed on cytology specimens could not be confirmed histologically. We feel this likely represents cytopathologic changes induced in response to the patient's active tuberculosis. To avoid aggressive systemic therapy in such cases, patients with localized lesions should have further diagnostic procedures to confirm the cytologic diagnosis histologically.
