Module 3 Clinical Manifestations

Introduction § 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.

Types of Tumors

Squamous 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)

Leukoplakia describes a white patch or plaque on the oral mucosa that cannot be wiped off and cannot be classified as another disease condition. Image used with permission from Dr. Sol Silverman and the American Cancer Society; Silverman, 2003: 29.

Leukoplakias are considered precancerous—the longer the lesion is present, the greater the chance of transformation to cancer. Image used with permission from Dr. Sol Silverman and the American Cancer Society; Silverman, 2003: 30.

Signs and Symptoms § A sore or area in the mouth that does not heal after two weeks § Persistent pain in the mouth § Persistent lump or thickening in the cheek § Sore throat or feeling that something is caught in the throat § Difficulty chewing or swallowing § Difficulty moving the jaw or tongue § Voice changes

Signs and Symptoms § Numbness in the tongue or other area of the mouth § Swelling in the jaw that causes dentures to fit poorly or become uncomfortable § Loosening of teeth or pain around the teeth or jaw § Lump or mass in the neck § Weight loss (unexplained) § Persistent bad breath

Summary • 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.
