Disorders of Tongue
• Glossodynia (burning mouth syndrome)- spontaneous burning, discomfort, pain, irritation, or rawness of the tongue, has no identifiable etiology most of the time
Etiology of Glossodynia
• Neurologic– Peripheral nerve
damage– Diabetic neuropathy – Trigeminal neuralgia
• psychiatric– Depression– Anxiety– Cancerophobia
• Systemic disorders– Anemia (iron deficiency,
pernicious)– Nutritional deficiency – Gastroesophageal reflux
disease– Sjogren syndrome– Hypothyroidism– Acquired immunodeficiency
syndrome
Treatment
• Tricyclic antidepressant
Disorders of Tongue…• Glossitis- presents as pain, irritation or burning, hypogeusia,
or dysgeusia
• Atrophic glossitis– Due to filiform de-papillation– Mild patchy erythema to a completely smooth, atrophic,
beefy-red surface
– Etiology - pernicious anemia, protein and other nutritional deficiencies, chemical irritants, drug reactions,, vesiculobullous diseases, oral candidiasis and systemic infections
Disorders of taste dysgeusia
• Viral infections• Candidiasis• Malnutrition• Neoplasms• Xerostomia• Metabolic disturbance• Drugs• Radiation• Zinc deficiency
COMMON LESIONS
Normal variations
Varicosities
Foliate papillae
They are occasionally mistaken fortumors or inflammatory disease
Developmental lesions
Fissured tongue
• normal variant seen in 5-11% individuals
• Numerous small irregular fissures oriented laterally on the dorsal tongue
• Also seen in - Melkersson-Rosenthal syndrome, psoriasis, Down syndrome, acromegaly, Sjogren syndrome
Macroglossia• Congenital or acquired process, tongue is disproportionately
large relative to the patient’s jaw size• Difficulty with mastication and speech and accidental tongue
biting are common• Differential- Down syndrome, hypothyroidism,
haemangioma, neurofibromatosis, infection by mycobacteria, or deep fungus, amyloidosis………
MicroglossiaMacroglossia\Fissured tongue
Hairy tongue• Hypertrophy of filiform papillae
resembling hair-like projections• Associated with - heavy tobacco
use, mouth breathing, antibiotic therapy, poor oral hygiene, general debilitation, radiation therapy, chronic use of antacids.
• White, yellow green, brown, or black color is due to chromogenic bacteria or staining from exogenous sources
Black hairy tongue
Brown hairy tongue
TREATMENT: Treatment consists of brushing the tongue with a soft bristle toothbrush . Surgical scraping.
1. What is the clinical diagnosis
2. What are the predisposing factors?
3. What is the treatment?
Geographic tongue
• Geographic tongue- benign inflammatory condition, due to loss of filiform papillae
• Erythematous plaques with well demarcated white border
• Etiology- idiopathic, psoriasis, Reiter syndrome, atopic dermatitis, idiopathic
Hemangioma of the lateral aspect of the tongue
Lingual thyroid
Other lesions
OraI hairy leukoplakia• Caused by Epstein-Barr
virus.• Presents as asymptomatic,
corrugated, white plaques with accentuation of vertical folds along the lateral borders of tongue
• Predominantly seen in HIV infection, organ transplant recipients and patients on chemotherapy
OraI hairy leukoplakia, Diagnosis
•DNA in situ hybridization•Biopsy
CandidiasisPseudomembranous
• Etiology• Predisposing factors• Classification• Treatment
Median rhomboid glossitis• Median rhomboid glossitis
- atrophic disorder of the tongue secondary to chronic candidiasis
Atrophic (erythematous) candidiasis
Squamous cell carcinoma• Early carcinoma may
clinically appear as leukoplakia or erythroplasia.
• The tongue and floor of the mouth are the most common areas
• PROGNOSIS: The overall five year survival rate is about 50%. Early diagnosis increases the chance of survival.
Leukoplakia
unilateral indurated white patch related to the lateral surface of the tongue.
EARLY SQUAMOUS-CELL CARCINOMA OF THE LATERAL BORDER OF THE
TONGUEEARLY SQUAMOUS-CELL CARCINOMA
OF THE FLOOR OF THE MOUTH
SQUAMOUS-CELL CARCINOMA PRESENTING AS EXOPHYTIC ULCERATED TUMOR OF THE
LATERAL BORDER OF THE TONGUE..
LATE SQUAMOUS-CELL CARCINOMA ON THE DORSUM OF THE TONGUE.
• DIFFERENTIAL DIAGNOSIS: All ulcerations present for more than 2-3 weeks in which there is no apparent cause should be biopsied to rule out carcinoma, especially in adults whose lesions are in high risk areas.
Traumatic ulcerSource of trauma should be identified
