What is stomatitis?

Stomatitis is inflammation of the mucous membrane of the mouth, including the inner aspect of the lips, cheeks, gums, tongue, and throat. It is a type of mucositis. It can be acute or chronic, mild or serious.

What investigations should be undertaken?

Relevant investigations depend on the likely cause of stomatitis and whether it is accompanied by other symptoms internally or skin rashes.

They may include:

  • Bacterial swabs
  • Viral swabs
  • Tissue scrapings for mycology
  • Biopsy for histology and direct immunofluorescence
  • Blood tests
  • Patch tests to identify contact allergy

What is the treatment of stomatitis?

Treatment for stomatitis depends on the cause. If it is due to allergy to a medication, the medication must be promptly stopped. However, it may be necessary to continue a causative medication when stomatitis arises as an expected adverse reaction to chemotherapy.

Infections may require specific treatment such as antibiotics for streptococcal pharyngitis, topical antifungal or oral antifungal agent for candida infection.

Nutritional deficiencies should be identified and corrected, for example, folic acid can reduce methotrexate-induced stomatitis.

Immunobullous diseases may be treated with systemic corticosteroids or other immunosuppressive treatments.
