Glossitis
Essentials
- Glossitis may be related to local conditions (infections, irritation) or be a sign of a systemic disease.
- Inflammation of the dorsal aspect of the tongue usually results in the loss of filiform papillae, i.e. atrophy (smooth tongue).
- The tongue may also have sores Oral Mucosal Ulcers or be affected by various diseases of the oral mucosa Viral Infections of the Oral Mucosa Assessment of Oral Mucosal Changes.
- Cancer of the tongue is hardly ever encountered on the dorsal surface of the tongue. Ulcers, leukoplakia and erythroplakia Assessment of Oral Mucosal Changes are an indication for a biopsy if they do not disappear within 2-3 weeks after the removal of potentially irritating factors. The patient should be referred to a dentist for a check-up of the mouth and for biopsy.
Inflammation of the median sulcus
- Atrophy around the median sulcus of the tongue, which affects the filiform papillae located in front of the circumvallate papillae (picture 1)
- A candidal infection, which may also present with other symptoms, including angular cheilitis Cheilitis and erythema of the roof of the mouth.
- The condition is more common in those wearing dentures and in smokers.
- Treatment consists of the removal of predisposing factors and topical antifungal therapy Fungal Infections of the Mouth
- Differential diagnosis
- Median rhomboid glossitis (pictures 2 3), also known as central papillary atrophy, which requires no treatment Benign Lesions of the Tongue
- Ulceration due to sarcoidosis or tuberculosis
Thrush (candidiasis)
- The surface of the tongue is covered with a white coating, which can be scraped off to expose the underlying erythematous mucous membrane.
- Often encountered in infants and elderly individuals in poor general health.
- Differential diagnosis: geographic tongue (pictures 4 5 6)
Atrophic glossitis (smooth tongue)
- The rough structure of the filiform papillae is lost (depapillation), and the tongue becomes smooth (picture 7).
- Erythematous patches may occur on the tongue or on the other mucous surfaces (pictures 8 9).
- Causes
- Treatment in accordance with the underlying disease where it has been identified.
Oedema of the foliate papillae
- Foliate papillae are ridged masses of mucous membrane that cover the sides of the posterior region of the tongue (lingual tonsils).
- The swelling may be caused by
- mechanical or chemical irritation, e.g. rubbing dentures, inflamed wisdom tooth
- upper respiratory tract infections
- Treatment consists of the removal of irritating factors
- Differential diagnosis
- Fibroma
- Ulceration
- Light-coloured lesions on the lateral margin of the tongue should be biopsied.
Granulomatous glossitis
- Chronic inflammation that may lead to permanent macroglossia
- Intermittent swelling of the tongue, which lasts for a few days
- The median sulcus is markedly deep
- A manifestation of the Melkersson-Rosenthal syndrome (see OMIM http://omim.org/entry/155900)
Geographic and fissured tongue
- See Benign Lesions of the Tongue and pictures 4 5 10.
- Unknown aetiology
- Does not require treatment.
- Often associated with psoriasis Psoriasis.
- Differential diagnosis
- Allergy, asthma
- Reiter syndrome
- Candida infection
Strawberry tongue
- A typical sign of scarlet fever
- Fungiform papillae on the tongue surface become erythematous and swollen
- Diagnosis is based on systemic symptoms.
