Abstract
Duodenal malignancies are not frequently encountered. Mostly they are either neuroendocrine tumors or adenocarcinoma, rarely adenosquamous. Periampullary adenocarcinomas are also commonly encountered which can be of either biliary or intestinal morphology. Either primary or metastatic scc to gastrointestinal tract are very rare. Metastasis can be from lung scc. So, here we want to present a rare pure squamous cell carcinoma of duodenum in a 65 yr old male patient without any primary site of malignancy or previous history of malignancy in relation with squamous cell carcinoma.
