title: Esophageal polypoidal mass: presentation of an uncommon pleomorphic carcinoma.
abstract: Pleomorphic carcinomas are primary malignant tumours that are known to arise in the lungs, pancreas, gall bladder and intestine. A patient with polypoid tumour of the esophagus is described in this report. The patient presented with dysphagia. Diagnostic and therapeutic intervention required endoscopic evaluation and treatment. Benign esophageal tumours are rarely seen and originate from the upper third of esophagus. We observed an esophageal tumour which was interpreted as spindle cell carcinoma of the esophagus that caused obstruction. We present the clinical picture and histopathological findings of the tumour. To our knowledge this is the first local report of spindle cell carcinoma occurring in the esophagus and describes its endoscopic and histopathological features with distinctive biphasic morphology.
