混合瘤是来自腺体上皮的肿瘤,含有外胚和中胚层成分。混合瘤大部分发生于涎腺,尤好发于腮腺。发生于鼻部者少见。国内文献中有74例鼻及鼻窦混合瘤记载,其中发生于鼻腔者24例,发生于鼻中隔者多见,其次为鼻腔外侧壁。我院于1999～2002年收治了两例鼻腔混合瘤患者,均在鼻内镜下经前鼻孔切除。现报道如下。 Mixed tumors are tumors from the glandular epithelium that contain both ectodermal and mesodermal components. Most of the mixed tumors occur in the salivary gland, especially in the parotid gland. Occurred in the nose are rare. There are 74 cases of nasal and sinus mixed tumor recorded in the domestic literature, of which 24 cases occurred in the nasal cavity, occurred in the nasal septum more common, followed by the nasal lateral wall. In our hospital from 1999 to 2002, two cases of nasal mixed tumor were treated, all under nasal endoscopic anterior nostril resection. Report as follows now.
