Epidemiological Analysis of Tongue Lesions in a Tertiary Health Facility in Tanzania

Abstract

Background: The tongue is susceptible to a multitude of conditions that can be of developmental, neoplastic, or inflammatory nature,  whose occurrence varies globally by age, sex, and ethnicity. The objective of the present study was to determine the incidence of tongue  lesions among cases managed in a tertiary hospital in Tanzania.

Methods: This study analyzed histological results of patients with tongue lesions diagnosed between 2016 and 2021. Data on the age and  sex of the patients and histological diagnosis were collected. Data analysis was done using Statistical Package for the Social Sciences version 27.

Results: A total of 190 samples of tongue lesions were studied and 18 different histological diagnoses were observed. Generally, a  majority (84.2%) of the biopsied tongue lesions were malignant. The most common (74.7%) lesions diagnosed were squamous cell  carcinoma followed by hemangioma (5.3%). A significant association was noted between the nature of the lesions and the age group and  sex of the patients.

Conclusion: This analysis depicts that tongue lesions are frequently encountered in patients managed in tertiary  health facilities in Tanzania. A majority of these lesions are malignant tumors. The sex and age of the patients are determining factors for  the occurrence of tongue lesions.
