Diseases of the
tongue
4. Introduction
The tongue is a complex organ involved in
speech and expression as well as in
gustation, mastication, and deglutition.
The oral cavity and the tongue are sites of
neoplasms, reactive processes, and
infections and may be a harbinger of
systemic diseases
5.
6. Functions of the tongue
Speech
Sucking
Taste
Digestion
Maintenance of oral hygiene
7. Glossitis
Glossitis is the term used for the red, smooth
and sore tongue
particularly characteristic of anaemia. These
features are a
combination of signs (redness and
smoothness) and a symptoms (soreness)
which are not always associated.
8. Important causes of
glossitis
• Anaemia
• Vitamin B group
(especially B12)
deficiencies
• Candidosis
9. Inx
Detailed haematological examination is
essential.
Treatment
treatment of specific causes quickly relieves
the symptoms.
10. Vascular and lymphatic lesions
(Infantile hemangiomas)
Infantile hemangiomas (IHs) are benign
vascular neoplasms and are the most
common soft tissue tumors in childhood
They are more prevalent in girls and most
commonly affect the head and neck region
The majority of growth of IHs is seen in the
first 2 months of life
11. Clinical features
Although oral IHs are rare relative to the skin, they
represent one of the most common lesions in the oral
cavity of children and often affect the tongue, buccal
mucosa, lips (soft tissue mass, pain, swelling and/or
discoloration)
the clinical differential diagnosis is dependent on the tumor
depth and includes pyogenic granuloma, angiosarcoma,
and other vascular tumors
12.
13. Treatment
The treatment of IHs is dependent on the risk
of compromise of vital organs and structures
as well as cosmesis.
Oral propranolol is now Food and Drug
Administration approved for IHs and has
become the gold standard for treatment
Response rates for propranolol are 98% with
a goal dose of 2mg/kg/day and 6 months of
therapy
14. Oral varices
Oral varices are a common developmental
anomaly noted in older adults.
The etiology of oral varicosities remains
unknown. Although the data are
controversial, there may be an association
with old age, smoking, and cardiovascular
disease
15. Oral varicosities most
commonly involve the
ventral tongue and are
characterized by
tortuous, asymptomatic,
compressible veins
16. Oral varices are commonly
seen on the lip, as
venous lakes, but are rare on
the buccal mucosa.
Treatment
is not necessary; however,
conservative excision of
cosmetically concerning
varices is often effective.
17. HAIRY TONGUE
The filiform papillae which are the cone-shaped
structures that don't contain taste buds, so have no
taste function
These filiform papillae can become elongated and
hair-like forming a thick fur on the dorsum of the
tongue.
The filaments may be up to half a centimetre long
and pale brown to black in colour Adults are affected
but the cause is unknown.
19. Risk factors
Heavy smoking, excessive use of antiseptic
mouthwashes, and
defective diet have been blamed, but their effect is
questionable
Treatment
The measure most likely to succeed is to persuade
the patient to scrape off the hyperplastic papillae and
vigorously cleanse the dorsum of the tongue with a
firm toothbrush.
Surgical removal by electrodessication
20. Fissured tongue
Fissured tongue (FT) is
a normal variant seen
in up to 20-30% of the
population,
characterized by an
increased number of
fissures and grooves at
the central and lateral
aspects of the tongue
This condition is idiopathic,
more common
in older individuals, and
thought to be a reactive
process
FT is the most common
tongue finding, seen in up to
one third of patients with
psoriasis
21.
22. Clinically, FT is
characterized by
multiple,
asymptomatic 2- to 3-
mm grooves and
fissures on the dorsal
surface of the tongue
There is no effective
treatment for FT;
however, we recommend
good oral hygiene with
brushing deep into the
fissures to remove
debris, lessen the
microbial burden, and
reduce halitosis .
23. Infectious conditions
Oral hairy leukoplakia
OHL is a corrugated white lesion seen on
ventral and lateral surfaces of the tongue
Commonly associated with HIV
EBV is the causative agent
24. Clinical features
Lesions are shaggy
and frayed
Plaque like and
often bilateral
Microscopy reveals
viral nuclear
inclusions
25. Treatment
No treatment is required usually but….
Resolves with Zidovudine, Acyclovir,
gancyclovir
Topical application of podophyllin and
tretinion
OHL is highly predictive of AIDS
development.
26. Oral candidiasis
Oral candidiasis is most commonly caused
by Candida albicans.
Median rhomboid glossitis is a unique form of
candidiasis that is characterized by large
rhomboidal, atrophic plaques on the
posterior-central tongue anterior .
The surface of the tongue may be lobulated
or smooth, and the lesions .
27. Clinical presentation
are always anterior to the
circumvallate papillae
The plaques are often
asymptomatic
Treatment with topical or oral
antifungals is effective.
28. Pernitious anemia
Chronic hematologic disease
Caused by lack of intrinsic factor used for
gastric sectretions
Triad of symptoms
1. Generalized weakness
2. Sore painful tongue
3. Tingling of extremities
30. Malignant neoplasms
(Squamous cell carcinoma)
SCC is the most common oral malignancy and is a
significant worldwide health issue.
Oral SCC is more common in men and in those older
than age 40 .
Extrinsic risk factors include tobacco, alcohol, and sun
exposure (if on the lip).
Intrinsic risk factors include immunosuppression,
longstanding
inflammation, LP, HPV infection, HIV infection, and
nutritional deficiencies
31.
32. clinical presentation
The clinical presentation of oral SCCs is highly
variable; therefore, one should maintain a high index
of suspicion , perform a biopsy early in the disease
course, and perform repeat biopsies in refractory oral
inflammatory diseases
Clues to the diagnosis include longstanding lesions,
irregular and ulcerated papules, nodules, and
plaques that extend above the normal epithelium
33. The most common sites are the posterior
lateral and ventral surface of the tongue.
The floor of the mouth is the second most
common location, whereas SCC of the dorsal
surface of the tongue is rare.
34. Treatment
Multimodal therapy with surgical excision,
chemotherapy,
Or
radiation remains the standard of care.
Recurrence is high in oral SCC; therefore,
long-term monitoring is required
35. Strawberry tongue
Strawberry tongue is
a term for a tongue
that is swollen and
bumpy. It is not a
health condition but
rather a symptom of
another disease.
37. symptoms
Strawberry tongue typically presents with the
following symptoms
Tongue rash
Swollen tongue
Increased tongue size
Small bumps on the tongue that look like strawberry
seeds
Redness on the tongue
38. Treatment
How to treat strawberry tongue depends on the
cause
Antibiotics (for bacterial infections)
IV immune globulin and aspirin (for Kawasaki
disease)
IV fluids
Pain relievers and fever reducers (for yellow fever)9
Antihistamines (for allergies)
Typically, the symptoms will also disappear when the
condition causing strawberry tongue resolves.
