title: [Digestive system carcinoma metastatic to the nasal cavity: two case report].
abstract: Metastatic tumors to the nasal cavity and paranasal sinuses are far less common than primary cancer in this location. The digestive system malignant tumor metastasis to the nose is rarer. The clinical presentation of metastases is similar to that of primary tumors and common symptoms include recurrent epistaxis, nasal obstruction and facial pain. Metastases to the nose and paranasal sinuses usually respond poorly to treatment and have a poor prognosis.
