试论述口腔白斑病的诊断与鉴别诊断。

答案

参考答案:口腔白斑病的诊断与鉴别诊断是:(1) 诊断要点:根据好发部位与临床表现进行诊断。病理诊断上皮角化异常,包括过度正角化、过度不全角化及混合过度角化,棘层增生,有上皮不典型增生,是一种癌前病变。固有层炎细胞浸润。由于已公认本病为癌前病变,具有恶变的潜能,应综合考虑下列因素加以警惕:年龄、性别、吸烟、部位、类型、组织病理不典型增生者伴有白色念珠菌感染者易发生癌变。(2) 鉴别诊断:白色角化病与初起的白斑不易鉴别,必要时可做活检。病理检查时,白色角化病的上皮细胞无不典型增生变化,而白斑长伴不典型增生。舌部白斑应与舌部萎缩型扁平苔藓相鉴别。

John Smith was a writer, who wrote detective stories for magazines(杂志), though he never dealt with criminals(罪犯). One evening he could not finish an end for a story. He sat in his study(书房), but he had no ideas. So he decided to go to the cinema.

When he came back, he found that he had had a visitor. Someone had broken into his house. The visitor had had a drink, smoked several of his cigarettes and had read his story. The visitor left him a note. “I have read your story and I don’t think it is very good. Please read my suggestions and you can finish it. By the way, I am a thief. I’m not going to steal anything tonight. But if you become a successful writer, I will return.”

John read the thief’s suggestions. Then he sat down and wrote the rest of the story. He is still not a successful writer, and he is waiting for his “visitor” to return. Before he goes out in the evening, he always leaves a half-finished story in his study.
