Most patients were presented with nasal blockage and difficulty in breathing. Occupational exposure to dust was present in the majority of patients. Tumors were composed of papillae or acini lined by dysplastic intestinal type columnar epithelium with interspersed goblet cells. There were 13 well differentiated (low grade) and 35 poorly differentiated (high-grade) tumors. CDX2 and SATB2 were expressed by the tumor cells in most tumors. Follow-up was available in 24 patients (range 3 months to 10 years). Most of the patients received chemo and\/or radiotherapy. Metastases occurred in 19 out of 24 patients. Brain metastases were very common. All patients with metastases died of their disease.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Clinical and morphological features in our series were similar to published studies.
