Positive sputum cytology in upper esophageal carcinoma

Research output: Chapter in Book/Report/Conference proceedingChapter


An unusual cause of positive sputum cytology is described. Upper esophageal carcinoma caused aspiration pneumonia. Examination of the sputum showed malignant cells suggesting the possibility of oat cell carcinoma. However, an esophagogram showed an obstructing carcinoma in the cervical esophagus, which, on endoscopic biopsy, proved to be undifferentiated squamous cell carcinoma. Esophageal carcinoma is an unusual cause of positive sputum cytology.
