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.
转移至鼻腔和鼻窦的肿瘤远比该部位的原发性癌症少见。消化系统恶性肿瘤转移至鼻部则更为罕见。转移瘤的临床表现与原发性肿瘤相似，常见症状包括反复鼻出血、鼻塞和面部疼痛。鼻部和鼻窦转移瘤通常对治疗反应不佳，预后较差。
