Clinicopathological analysis of nasopharyngeal tuberculosis.

BACKGROUND

The aim of this study is to examine the clinical and pathological attributes of nasopharyngeal tuberculosis.

METHODS

We conducted a retrospective analysis of the clinicopathologic characteristics of nasopharyngeal tuberculosis in 14 patients. The medical records and imaging data obtained between March 2004 and February 2023 were scrutinized. During the pathological review, we classified the types of granulomatous inflammation and graded the extent of caseation.

RESULTS

Results indicate a 100% female predominance, with chief complaints including hearing loss, postnasal drip, and nasal obstruction. Cervical lymphadenopathy occurred in 21.4% of patients. Chest radiograph abnormalities were found in 58.3%, with three showing active pulmonary tuberculosis. Endoscopic examination revealed three types of lesions, and CT/MRI findings correlated with gross lesions. A statistically significant association was found between lesion characteristics (bulging, ulcerative, necrotic) and pathology patterns (sarcoidosis-like, caseation). Bulging masses exhibited sarcoidosis-like patterns, while ulcerative/necrotic lesions were often associated with caseation. All lesions responded well to over six months of anti-tuberculosis medication, leading to favourable outcomes.

CONCLUSION

We studied 14 cases of nasopharyngeal tuberculosis, mostly in females, with common ear and nose symptoms. Lesions were typically visible on nasopharyngeal endoscopy, and endoscopically bulging mass-like lesions had pathologically sarcoidosis-like granulomas. All patients had favourable outcomes.
