乳头状瘤由于组织表现特异,病名紊乱,但以“内翻性乳头状瘤”(Inverted Papilloma简称IP)为主。该肿瘤来自外胚层的Scheiderian膜,这层膜复盖在鼻腔外侧壁、鼻甲和鼻窦。据近年来报道,本病在儿童极少见,多见于50～60岁成年男性,男女之比为3～10:1,发病率0.5～4％之间不等。易复发,易恶变。 Papilloma is characterized by a specific tissue and disordered disease, but it is mainly referred to as Inverted Papilloma (IP). The tumor is derived from the ectoderm Scheiderian membrane, which covers the lateral wall of the nasal cavity, turbinates and sinuses. According to reports in recent years, the disease is rare in children, more common in adult males aged 50 to 60 years, the ratio of male to female is 3 to 10:1, and the incidence rate varies from 0.5 to 4%. Easy to relapse, easy to change.
