Median Rhomboid GlossitisMedian rhomboid glossitis is the term used to describe a smooth, red, flat or raised nodular area on the top part (dorsum) of the middle or back of the tongue. Median rhomboid glossitis is the term used to describe a smooth, red, flat or raised nodular area on the top part (dorsum) of the middle or back of the tongue. The affected area of the tongue is missing its normal coating of finger-like projections called filiform papilla, which normally cover the entire top surface of the tongue. The name of this lesion reflects its location and describes it. Median implies that the affected area is located near the center of the tongue, rhomboid refers to the shape of the affected area, and glossitis means inflammation. Median rhomboid glossitis is present in about 1% of the population and most often affects men between the ages of 30 – 50 years of age. It typically presents as an ovoid area about 2 – 3 centimeters long in its longest dimension (see Right). As most cases of median rhomboid glossitis are without symptoms, it is often first noticed by the dentist during a routine examination. However, some patients may experience a burning sensation when eating certain foods. Median rhomboid glossitis is currently thought to represent a chronic fungal (candidiasis) infection in this area of the tongue (see PATIENT INFORMATION SHEET - Oral Yeast Infections). Sometimes a “kissing” lesion develops on the palate, directly opposite from the tongue lesion. This is more common in people whose immune system is suppressed and is believed to result from the fungal organisms on the top of tongue being transferred to the palate during swallowing and similar movements.
