Giant-cell carcinoma of the lung. A cytologic study

A case of giant-cell carcinoma of the lung, confirmed at autopsy, is presented. The cytologic features seen in sputum samples, bronchial washings and brushings and fine needle aspiration biopsy material as well as the histologic findings are described. The possible relationship to bronchioloalveolar carcinoma is discussed. The cytologic features of giant-cell carcinoma of the lung, when seen in the context of the clinical and radiologic setting, should allow the cytologic identification of the tumor prior to surgical intervention.
