目的 分析鼻咽癌临床误诊的原因从中吸取教训。方法 回顾性分析 6例病例。结果 误诊原因为 6例病人中 2例未及时作鼻咽部活检 ;2例因病灶位置隐蔽 ,经多次鼻咽部检查方才确诊 ;有 2例鼻咽部虽然经多次检查仍为阴性而取颌下肿块作了活检证实为转移癌灶。结论 鼻咽癌诊断困难原因主要有医生对此病警惕性不够和症状及体征不典型 ,活检取材位置不正确和深度不够。对面颈部包括腮腺区及颌下、颏下肿块患者要仔细检查鼻咽部 ,多次、多部位深取材活检才能得出正确的诊断。以及对鼻咽部多次检查阴性而腮腺区、颌下、颏下肿块增大迅速及时进行肿块组织学检查
Objective To analyze the causes of misdiagnosis of nasopharyngeal carcinoma (NPC) from which to draw lessons. Methods Retrospective analysis of 6 cases. Results The cause of misdiagnosis was that 2 of the 6 patients did not make nasopharyngeal biopsy in time; 2 patients were hidden by the location of the lesion and had been confirmed by multiple nasopharyngeal examinations. Although nasopharyngeal biopsies were still negative in 2 patients Submandibular mass was taken biopsy confirmed metastatic foci. Conclusions The main reasons for the difficulties in the diagnosis of nasopharyngeal carcinoma are the insufficient vigilance of doctors, the atypical symptoms and signs, the incorrect location of the biopsy and the insufficient depth. Opposite the neck, including the parotid gland area and submandibular, submental mass of patients to carefully examine the nasopharynx, multiple, multi-site deep drawn biopsy can arrive at the correct diagnosis. And multiple negative nasopharyngeal examination of the parotid gland area, submandibular, submental mass rapidly and timely mass histological examination
