title: Expectoration of bronchogenic carcinoma.
abstract: A case of expectoration of primary squamous cell bronchogenic carcinoma is reported. Only two previous cases of expectoration of grossly visible fragments of primary bronchogenic carcinoma have been reported. Interestingly enough these were also squamous cell carcinomas. Patients suspected of having pulmonary neoplasm should be instructed to save any grossly visible expectorated tissue fragments.
