1Module 3
2Introduction
- Intraoral cancers occur most frequently on the
- Tongue
- Floor of the mouth
- Soft palate and
- Oropharynx
- Squamous cell carcinoma is the most common type,
accounting for 90 of oral cancers.
3Types of Tumors
4Squamous Cell Carcinoma
- The most common presentations of intraoral
squamous cell carcinoma are - exophytic (mass-forming)
- endophytic (ulcerated)
- leukoplakic (white patches)
- erythroplakic (red patches) and
- erythroleukoplakic (combined white and red
patches)
5Leukoplakia
Leukoplakia describes a white patch or plaque on
the oral mucosa that cannot be wiped off and
cannot be classified as another disease
condition.

6Leukoplakia
Leukoplakias are considered precancerousthe
longer the lesion is present, the greater the
chance of transformation to cancer.

10Plaque Form of Candidiasis
Candidiasis can be wiped off with gauze or an
instrument.

11Verrucous Leukoplakia
Verrucous leukoplakia should be treated
aggressively.

12Leukoplakia
Recurrences of white and/or red lesions are
common, so frequent follow-up is necessary.

14Hairy Leukoplakia
Hairy leukoplakia is a benign condition that
signals HIV infection.

15Leukoplakia
All chronic white and/or red lesions should be
carefully monitored and biopsied.

16Erythroplakia
Erythroplakia appears as a red lesion that may
demonstrate an erosive component.

17Erythroleukoplakia
Erythroleukoplakia has both white and red
components.

18Erythroleukoplakia
These lesions are 4 times more likely to undergo
a malignant transformation than other types.

19Erythroleukoplakia
Red lesions present after 14 days should be
biopsied or referred to a specialist.

23Tongue Carcinoma
The tongue is increasingly a site for oral cancer
in young individuals with no apparent risk
factors.

24Tongue Carcinoma
Carcinomas of the tongue account for 25 of all
oral squamous cell carcinomas and half of
intraoral lesions.

25Floor of the Mouth
Approximately 25 of oral carcinomas occur in the
floor of the mouth region.

area.

28Carcinoma of the Soft Palate
Due to their posterior location, patients are
often unaware of the presence of these lesions
and diagnosis may be delayed.

37Summary
- Oral cancer may appear as erythroplakia,
leukoplakia, or erythroleukoplakia. - Common locations include the tongue (50), floor
of the mouth (25), soft palate/oropharynx (15),
and gingiva (5) or buccal mucosa (5) - Lesions that may mimic oral cancer include
candidiasis, oral lichen planus or physical
trauma.
