Irregular Red Patches on the Dorsum of the Tongue: Benign Migratory Glossitis

Abstract

Depapillation which leads to pink or red areas of the tongue can occur due to many conditions. The fundamentals of arriving at a diagnosis depend on a good history and examination. The location, colour and shape of the depapillated area and associated symptoms are useful information to narrow down the diagnosis. Benign migratory glossitis (BMG) is unique as it is mostly asymptomatic, and the depapillated pink/red areas change its colour, shape and location. The red areas are surrounded by a well-defined elevated margin and are located mostly towards the lateral margins of the dorsum of the tongue. BMG does not require treatment as it is a benign condition which is not associated with other medical conditions. As the appearance can cause concern to the patient, reassurance and patient education are of prime importance. Rare symptomatic cases may be managed with mild anti-inflammatory agents, topical steroids and antifungals.
