鼻咽癌容易与哪些疾病混淆?

来源:华人健康网 | 发布时间:2012-12-14 00:00:25 | www.chinesejk.com

  1、鼻咽部淋巴肉瘤

  淋巴肉瘤好发于青年人原发肿瘤较大常有较重鼻塞及耳部症状该病淋巴结转移不单局限在颈部全身多处淋巴结均可受累颅神经的损伤不如鼻咽癌多见最后需要病理确诊

  2、增生性病变

  鼻咽顶壁顶后壁或顶侧壁见单个或多个结节隆起如小丘状大小约0.5~1cm结节表面粘膜呈淡红色光滑多是在鼻咽粘膜或腺样体的基础上发生亦可由粘膜上皮鳞状化生后角化上皮潴留而形成表皮样囊肿的改变部分是粘膜腺体分泌旺盛形成潴留性囊肿当结节表面的粘膜出现粗糙糜烂溃疡或渗血需考虑癌变的可能应予活检以明确诊断

  3、鼻咽部结核患者多有肺结核病史除鼻阻涕血外还有低热盗汗消瘦等症检查见鼻部溃疡水肿颜色较淡;分泌物涂片可找到抗酸杆菌可伴有颈淋巴结核;淋巴结肿大呈马铃状粘连无压痛颈淋巴结穿刺可找到结核核菌CT试验强阳性X线胸片常提示肺部活动性结核灶

  4、咽粘膜炎症 表现为粘膜粗糙尤其是重度炎症时鼻咽粘膜滤泡增殖表面凹凸甚至可呈桑椹样表面附有脓性分泌物常需与粘膜浸润性癌相鉴别

  5、过敏性鼻炎 鼻咽粘膜苍白光滑呈水肿样

  6、萎缩性鼻炎 鼻咽顶前粘膜有浅在性溃疡周围有脓性分泌物需与溃疡型鼻咽癌鉴别
