Median Rhomboid Glossitis: A Case Study

Abstract

A smooth, red, oval, or rhomboid patch on the dorsal midline is the classic presentation of median rhomboid glossitis (MRG), a rare and benign lesion of the tongue. MRG is still not fully understood, which presents diagnostic hurdles and calls for additional clinical investigation. It is frequently associated with candidal infections. We describe a case of a 42-year-old man who initially appeared to have either mechanical irritation or thermal injury related to a painless patch on the dorsum surface of the tongue. We document a case of MRG that was consulted for a standard dental examination in this case report. This article also highlights a dentist's need to identify the lesion and provide appropriate education for the patient.
