2. INTRODUCTION
The tongue is a complex set of sensory papillae and
muscles.
3 forms of taste buds:
• Fungiform (edges and tip)
• Circumvallate (posteriorly in V shape )
• Foliate papillae (posterolateral)
The filiform papillae - devoid of sensory fibers and are
not true taste buds.
18. HAIRY TONGUE(lingua villosa)
• Also called as furred tongue
• Defective desquamation of the filiform papillae leading
to the retention hyperkeratosis.
19. HAIRY TONGUE
• Poor oral hygiene
• Smokers
• Mouth breathers low fiber diets
• Febrile patients.
• HIV infection
• Radiation treatment to head and neck
• Graft-versus host disease
• Drugs - most common being antibiotics-tetracyclines
atypical antipsychotics
antidepressants
anti-cholinergics.
20. BLACK HAIRY TONGUE
• Black hairy tongue seen as the complication of hairy
tongue
• Occurs when bacteria are trapped in the filiform papillae
and produce pigments causing a brown/black colour.
• The presence of other microbes such as candida, can
exacerbate this condition.
24. Workup for hairy tongue
• Unless there are stigmata of underlying disease or
symptoms, such as pain, no additional workup is needed.
• In refractory or atypical cases, a biopsy and cultures or
PCR for bacteria, fungus, and HSV may be warranted.
25. TREATMENT OF HAIRY TONGUE
• Regular brushing of the tongue using 1.5% hydrogen
peroxide (5 to 10 strokes daily) with a hard toothbrush.
• Topical retinoids, antifungals, and keratolytics.
• Oral therapy with antifungals, antibiotics and antivirals
for refractory cases with positive cultures.
26. STRAWBERRY TONGUE
Hypertrophy of fungiform papillae and then
desquamation
Papillae appear as large red knobs giving the
appearance of stawberry tongue(rasberry tongue)
Seen in
Scarlet fever
Toxic shock syndrome
Kawasaki disease
29. LEUKOPLAKIA
• It is a white patch in the mucosa of oral cavity that cannot
be characterised clinically or pathologically to any other
diseases.
• It is a premalignant condition
• Dysplasia and of dyskeratosis leading to formation of
thick , white and pearly raised plaques giving whitish
appearance of part of tongue.
• Predisposing factors
Spices, betel nut chewing
Smoking, tobacco chewing
Infective or mechanical (dental irritation)
32. ORAL HAIRY LEUKOPLAKIA
• Seen on lateral margins of tongue as several white areas
• Cannot be wiped off with gauze.
• Immuno-compromised patients-AIDS
• Associated with Epstein Barr virus
34. • It is painless
• Has no malignant potential.
• First line topical treatment includes topical retinoids,
podophyllin, and acyclovir
• The underlying HIV infection should be treated or the
immunosuppressed states should be modified.
35. PIGMENTATION OF TONGUE
Dark brown or black patches on tongue
1. Addisons
2. Nelsons syndrome
3. Peutz jeghers
4. Malabsorption
5. Acanthosis nigricans
39. Fissured Tongue(scrotal tongue)
• A normal variant seen in up to 20% to 30% of the
population
• Characterized by an increased number of fissures and
grooves at the central and lateral aspects of the tongue.
• Very severe fissuring is often referred to as “lingua
plicata.”
42. • Treatment
• Good oral hygiene with brushing deep into the fissures
in order to remove debris, lessen the microbial
burden, and reduce halitosis.
• If pain is present- therapy should be targeted at
reducing inflammation or eradication of the
infection.
43. COBBLESTONE TONGUE
Due to hyperemic and hypertrophied papillae with
thickened epithelium
• Ariboflavinosis(with magenta colour)
• Syphilis
CROCODILE SKIN TONGUE
• In Sjogren’s syndrome, there is dorsal papillary
atrophy & furring of the tongue
45. SMOKER’S PATCH
• Small, raised, smooth, congested area frequently
covered with a crust on the dorsum of tongue
• White umbilicated papules with a central brown spot
on palatal mucosa
LEPROTIC NODULES
• May develop on anterior 2/3rd of tongue especially
near tip
47. Benign Migratory Glossitis
• = GEOGRAPHIC TONGUE.
• Benign, inflammatory condition
• Prevalence-1 to 2% of the population ,more common in
young patients.
• Etiology-rapid loss and regrowth of filiform papillae
leading to denuded red patches wandering across the
tongue surface.
• It is more common in Psoriasis(14%), and some argue
that it is an oral manifestation of psoriasis
48. It is characterized by an annular arrangement of
alternating raised, hyper keratotic plaques and smooth,
atrophic red patches.
Red- atrophic filiform papillae
White-hypertophic filiform papillae
Dynamic and change over time creating a “migratory
pattern”
50. Treatment of geographic tongue
• Generally no treatment required.
• If burning pain or sensitivity to foods present -topical
corticosteroids as well as topical calcineurin inhibitors.
51. MEDIAN RHOMBOID GLOSSITIS
• Red depapillated area in the centre of dorsum of
tongue
• Believed to be associated with candidiasis and a
marker of underlying immunosuppression.
• Biopsy may show pseudo-epitheliomatous hyperplasia
• Responds to antifungal treatment
53. Oral candidiasis
Creamy white curdlike patches that reveal a raw, bleeding
surface when scraped.
• Debilitated elderly patients
• High-dose glucocorticoids, broad-spectrum antibiotics
• Patients with AIDS
62. CARCINOMATOUS ULCER
• Usually single
• Common on side or tip of tongue
• Hard, indurated
• Irregular ,deep, raised everted margins
• Associated with slough
• Impaired mobility of tongue
• Regional lymphnode enlargement
79. MISCELLANEOUS CONDITIONS
AMYLOID TONGUE
• Appears enlarged & presents as mottling of dark purple areas with
translucent matter
MUCOSAL NEUROMA OF TONGUE
MEN II b syndrome
ALLIGATOR TONGUE
• Dry, thick, furrowed & irregular tongue
• Seen in Diabetes mellitus

Editor's Notes
Normal papillae are 1 mm in length; however, in HT there is
defective desquamation of cells in the central column of the filiform papillae, causing an increase
in length 10 to 20 times normal
