喉部上皮增生指喉粘膜呈白斑病变的疾患,历来将角化、厚皮病、棘皮瘤、白斑症和增殖性喉炎均归入此类,一般认为属癌前状态,因为后来有的发生癌变。所以,对喉部白斑病变须慎重对待。作者们对1971～1978 8年间诊断为本病的63例患者进行了临床分析,其中35例行手术和病理检查。对癌变病例探讨了能否预知癌变的可能性,对喉粘膜白斑病变试行病理组织分类。 Hyperplasia of the laryngeal epithelium refers to a disease of leukoplakia on the laryngeal mucosa. Historically, keratinization, thick skin disease, acanthosis, leukoplakia, and proliferative laryngitis have been classified in this category. They are generally considered to be precancerous conditions because some of them have occurred later. Carcinogenesis. Therefore, the white spot lesions should be treated with caution. The authors performed a clinical analysis of 63 patients diagnosed as the disease during the 8 years from 1971 to 1978, and 35 of them underwent surgical and pathological examinations. The possibility of cancer prediction was explored for cancerous cases, and pathological classification of leukoplakia was performed.
