Identifying Chili as a Risk Factor for the Geographic Tongue: A Case Report

INTRODUCTION: Geographic tongue (GT) is a chronic tongue condition triggered by various factors such as immune reactions, allergies, stress, hereditary factors, and nutritional deficiencies.

The prevalence of GT in the population ranges from 1% to 3%, and its symptoms can cause discomfort to patients.

Spicy foods are popular among Indonesians.

Chili is one such food that can cause allergies and trigger GT.

OBJECTIVE: This report highlights the significance of identifying the risk factors associated with symptomatic GT.

CASE: A 19-year-old female patient complained of a rough and sore dorsal tongue for a year, particularly after consuming spicy food.

Extra-oral examination revealed dry lips.

Intra-oral examination showed red patches with white borders on the dorsal tongue.

A complete blood count and allergy test were performed.

The eosinophil count was 4%, the total IgE level was 698 IU/mL, and the skin prick test for chili was positive.

The diagnosis of chili-induced GT was made.

CASE MANAGEMENT: The patient was advised to avoid chilies, and benzydamine hydrochloride mouthwash was administered.

One week after treatment, clinical improvement was observed.

Severity decreased on the Geographic Tongue Area and Severity Index (GTASI) from 12 (moderate) to 0.4 (mild).

Pain decreased from 6 to 0 on the numerical rating scale (NRS).

CONCLUSION: Management of symptomatic GT includes the avoidance of allergens such as chilies and appropriate pharmacological therapy.

The identification of risk factors is required for effective management.
