Median Rhomboid Glossitis: A Rare Oral Condition

Median rhomboid glossitis (MRG) is a rare and benign oral condition characterized by a smooth, red, flat or raised nodular area on the top part (dorsum) of the middle or back of the tongue [8][10]. This condition affects approximately 0.01% to 1.0% of the population [3][13], with males being primarily affected [2-4].

Key Features

• MRG is a well-demarcated area of depapillation on the dorsum of the tongue, typically anterior to the circumvallate papillae [6][7].
• The affected area may appear smooth and glossy due to the loss of lingual papillae [4].
• It can be located in the middle or back of the tongue, with a characteristic rhomboid-shaped erythematous patch in the center of the tongue's dorsum anterior to the circumvallate papillae [11].

Symptoms and Treatment

MRG is often asymptomatic, but some people may experience a burning sensation when eating [1]. In symptomatic cases or if patients desire treatment, topical anti-yeast treatments such as nystatin suspension or clotrimazole troches can be tried for a 2-week period [12].

Important Notes

• MRG is not a malignant lesion and is often associated with fungal infections like candidiasis [5].
• A biopsy should be done after a round of antifungal therapy has been completed if there's any doubt regarding its nature [1][3][4].

Median Rhomboid Glossitis: Signs and Symptoms

Median rhomboid glossitis, also known as central papillary atrophy or Hunter glossitis, is a condition characterized by the loss of lingual papillae on the top part (dorsum) of the middle or back of the tongue. The signs and symptoms of median rhomboid glossitis can vary from person to person, but here are some common ones:

• Redness: A red, smooth, flat or raised area is often visible on the dorsum of the tongue.
• Loss of lingual papillae: The tiny bumps on the tongue that contain taste buds (lingual papillae) may be lost, giving the tongue a smooth appearance.
• Pain and discomfort: Some people may experience mild burning or itching sensations in the affected area.
• No other symptoms: In most cases, median rhomboid glossitis is asymptomatic, meaning there are no other signs or symptoms.

Key Features

• Median rhomboid glossitis affects up to 1% of the population and is more prevalent in men, immunosuppressed patients, patients with diabetes, and patients taking broad-spectrum antibiotics.
• The condition typically presents as a well-demarcated area of depapillation (loss of lingual papillae) on the dorsum of the tongue.

Causes and Risk Factors

Median rhomboid glossitis is often caused by a Candida yeast infection. Other risk factors include:

• Immunosuppression: Weakened immune systems can increase the risk of developing median rhomboid glossitis.
• Diabetes: People with diabetes are more likely to develop this condition.
• Broad-spectrum antibiotics: Taking broad-spectrum antibiotics can disrupt the balance of good and bad bacteria in the mouth, leading to an overgrowth of Candida.

Diagnostic Tests for Median Rhomboid Glossitis

Median rhomboid glossitis (MRG) is a rare developmental condition of the tongue, and its diagnosis can be challenging. While there are no specific tests to confirm MRG, several diagnostic approaches can help identify this condition.

• Clinical Diagnosis: In most cases, median rhomboid glossitis can be diagnosed clinically by a dentist or an oral medicine specialist based on its characteristic appearance (1, 5, 7). The lesion's surface may be nodulated or smooth, and it is usually located in the middle or back of the tongue.
• Laboratory Tests: Laboratory tests are not typically required for diagnosing MRG. However, if there is a suspicion of an underlying infection or nutritional deficiency, laboratory tests such as blood tests or a swab of saliva may be ordered (13, 14).
• Imaging Studies: Imaging studies such as radiographs or ultrasound may be used to rule out other conditions that can cause similar symptoms.
• Biopsy: In some cases, a biopsy may be performed to confirm the diagnosis and rule out other conditions. However, this is not typically necessary for diagnosing MRG (8).

Key Points

• Median rhomboid glossitis is usually diagnosed clinically by a dentist or oral medicine specialist based on its characteristic appearance.
• Laboratory tests are not typically required for diagnosing MRG.
• Imaging studies and biopsy may be used to rule out other conditions.

Treatment Options for Median Rhomboid Glossitis

Median rhomboid glossitis (MRG) is a condition characterized by an area of redness and loss of lingual papillae on the central dorsum of the tongue. The treatment options for MRG are similar to those for oral candidiasis, which is a fungal infection that can cause symptoms such as pain or burning sensation in the mouth.

Antifungal Medications

The primary treatment for MRG involves the use of antifungal medications to kill the yeast and reduce symptoms. Some common antifungal agents used to treat MRG include:

• Nystatin: This is a polyene antifungal agent that can be used to treat MRG.
• Fluconazole: This is an azole-group antimycotic that can be used to treat MRG.
• Miconazole: This is another azole-group antimycotic that can be used to treat MRG.
• Clotrimazole: This is a topical antifungal agent that can be used to treat MRG.

Other Treatment Options

In some cases, additional treatment options may be necessary. These can include:

• Biopsy: A biopsy can be performed after a round of antifungal therapy if the symptoms persist.
• Anxiolytics: In some cases, anxiolytics may be prescribed to help manage anxiety or stress related to the condition.

Importance of Accurate Diagnosis

It's essential to accurately diagnose MRG and rule out other conditions that may cause similar symptoms. A correct diagnosis can ensure that the most effective treatment is used, which can improve outcomes for patients with MRG.

Median rhomboid glossitis, also known as central papillary atrophy of the tongue, has a differential diagnosis that includes several conditions that can present with similar symptoms.

Conditions to Consider:

• Erythroplakia: A condition characterized by red patches on the mucous membranes, including the tongue. It is often associated with dysplasia or cancer.
• Geographic tongue: A benign condition where the papillae on the surface of the tongue appear as if they are "geographically" arranged, with areas of smoothness and roughness.
• Granular cell tumor: A rare, benign tumor that can occur on the tongue, often presenting as a painless, firm nodule.
• Candida infection: A fungal infection that can cause redness, swelling, and white patches on the mucous membranes, including the tongue.
• Chemical burns: Burns caused by exposure to chemicals or other substances that can damage the mucous membranes.
• Syphilis patches: Patches of skin-like lesions that can occur in the mouth, including the tongue, as a sign of syphilis infection.
• Lingual thyroid: A rare condition where thyroid tissue is present on the surface of the tongue.
• Tertiary gummatous syphilis: A complication of untreated syphilis that can cause gum-like lesions to form in the mouth.

Key Points:

• Median rhomboid glossitis should be considered in the differential diagnosis for patients presenting with redness and loss of lingual papillae on the central dorsum of the tongue.
• The condition is often associated with chronic atrophic oral candidiasis, but other conditions such as hematinic deficiency and diabetes should also be excluded.
• A thorough clinical examination and medical history are essential to differentiate median rhomboid glossitis from other conditions.
