Nasopharyngeal masses in adults—A retrospective analysis of 255 patients to evaluate symptoms, clinical findings, and histological results

Abstract

AbstractBackgroundNasopharyngeal tissue hyperplasia is generally associated with adenoids in childhood. In adults, nasopharyngeal masses are occasionally found, but data on symptoms, clinical findings, and histologic results are limited.Material and MethodsA 10‐year retrospective study was conducted, analyzing data from adult patients who underwent nasopharyngeal biopsies. The study included information on case history, preoperative suspected diagnosis, and histology type. Statistical analysis was performed.ResultsTwo hundred and fifty‐five patients were included, most of them complaining of nasal obstruction, ear pressure, and hearing loss. Biopsy revealed adenoid tissue (64.7%), solid malignancies (15.7%; dominant undifferentiated carcinoma), lymphomas (9.0%), cysts (7.8%), and other benign tumors (2.7%). Malignant neoplasms were predominantly found in male and in elderly patients (P < 0.0001). If a malignant tumor was suspected initially, histological examination confirmed this in 75% of the cases. 45% of patients with a malignant nasopharyngeal mass had a unilateral seromucous tympanum.ConclusionsPersistent nasopharyngeal masses in adults—particularly in elderly men, smokers and those with simultaneous unilateral seromucous tympanum—should undergo a histological examination.
