Clinical Characteristics and Risk Factors of Geographic Tongue: A Retrospective Analysis of 100 Polish Patients

<b>Background/Objectives:</b> We aimed to evaluate the clinical course, demographic characteristics, and risk factors in Polish patients with geographic tongue (GT). <b>Methods:</b> The analysis was based on medical records of 100 patients with GT referred to the outpatient clinic of Poznań University of Medical Sciences (PUMS) from 2013 to 2023. Data regarding age, gender, medical history, habits, subjective complaints, clinical features, localization, histology, and treatment were considered. <b>Results:</b> Patients with GT constituted 11.3% of 887 individuals admitted to the outpatient clinic in the analyzed period. The female-to-male ratio was 52:48. The average age at diagnosis was 51.6 years. Thirteen patients reported smoking, and 2.0% admitted to consuming alcohol excessively. Subjective complaints were reported by 85.0% of patients and mainly included a burning sensation (57.0%), pain (39.0%), xerostomia (22.0%), bleeding (4.0%), and taste disturbance (3.0%), while 15.0% of GT patients were asymptomatic. Comorbidities were found in 76.0% of subjects with GT, and included cardiovascular disorders (37.0%), gastrointestinal and thyroid gland diseases (24.0% and 18.0%), and type II diabetes (15.0%). Psoriasis was observed in one case only. <b>Conclusions:</b> The frequency of GT in a Polish cohort of patients was high and comparable in both genders. The majority of participants reported subjective complaints, and most of the patients were non-smokers. Comorbidities were found in 76.0% of subjects with GT and mainly included cardiovascular and gastrointestinal diseases. GT was often accompanied by other oral conditions, like candidiasis, recurrent aphthous stomatitis, and lichen planus. GT screening should include cardiovascular and gastrointestinal evaluation.
