An analysis of clinical presentation and misdiagnosis in patient with nasopharyngeal carcinoma

Objective: To investigate the clinical presentation and misdiagnostic causes of 507 patients with nasopharyngeal carcinoma. Methods: The analysis was performed in 507 cases of the nasopharyngeal carcinoma treated from January 1996 to the end of 1999. Results: The clinical presentation of patients with nasopharyngeal carcinoma includes epistaxis, nasal obstruction, ear pain, hearing loss, headache, cervical lymph node involvement, cranial nerve involvement and horner's syndrome. At the time of initial diagnosis, the rate of misdiagnosis was 86.98% for all cases. The duration before getting pathologic document was longer in patient with mild symptoms such as epistaxis, nasal obstruction and/or ear pain than that with headache, cranial involvement and/or cervical lymph node involvement. Conclusion: Our results demonstrate that it is an important procedure for patients with symptoms linking to nasopharyngeal carcinoma to receive careful examination for the ear, nasopharynx and nose.
