Frictional Keratosis in the Oral Cavity

Which of the following best describes the cause of frictional keratosis?

• Chronic rubbing or friction against an oral mucosal surface

• Viral infection of the oral mucosa

• Bacterial invasion of the gums

• Genetic mutation affecting oral tissues

What is the typical appearance of frictional keratosis in the oral cavity?

• Opaque white

• Bright red

• Bluish-black

• Yellowish-brown

What are the recommended steps in the treatment of frictional keratosis?

• Identify the traumatic cause of the lesion and eliminate the cause

• Prescribe antibiotics and painkillers

• Perform surgical removal of the lesion

• Apply topical steroids only

Why must frictional keratosis be differentiated from idiopathic leukoplakia?

• Because leukoplakia may be premalignant

• Because frictional keratosis is always malignant

• Because leukoplakia is caused by bacteria

• Because frictional keratosis is viral in origin

A patient presents with an opaque white lesion on the oral mucosa. What reasoning process should you use to determine if it is frictional keratosis or leukoplakia?

• Assess for a history of chronic trauma or friction and rule out other causes, considering the premalignant potential of leukoplakia

• Immediately prescribe antibiotics

• Assume all white lesions are benign

• Ignore the lesion unless it is painful

Where is a smokeless tobacco keratosis lesion most often located?

• On the tongue

• In the mucobuccal fold

• On the hard palate

• On the uvula

Which of the following best describes the appearance of early lesions of smokeless tobacco keratosis?

• Smooth and red

• Granular or wrinkled

• Ulcerated and bleeding

• Blue and swollen

How do long-standing lesions of smokeless tobacco keratosis typically differ from early lesions?

• They become more opaquely white and have a corrugated surface

• They turn red and smooth out

• They disappear completely

• They develop into ulcers

A patient presents with a white, corrugated lesion in the mucobuccal fold where they place chewing tobacco. Using evidence from the description, what is the most likely diagnosis?

• Oral candidiasis

• Smokeless tobacco keratosis

• Herpetic lesion

• Aphthous ulcer

Which of the following best describes a traumatic neuroma?

• A lesion caused by injury to a peripheral nerve; benign, nonneoplastic, and very rare

• A malignant tumor of the central nervous system

• A common infection of the oral mucosa
