Common oral lesions: Part II. Masses and neoplasia.
Certain common oral lesions appear as masses, prompting concern about oral carcinoma. Many are benign, although some (e.g., leukoplakia) may represent neoplasia or cancer. Palatal and mandibular tori are bony protuberances and are benign anomalies. Oral pyogenic granulomas may appear in response to local irritation, trauma, or hormonal changes of pregnancy. Mucoceles represent mucin spillage into the oral soft tissues resulting from rupture of a salivary gland duct. Oral fibromas form as a result of irritation or masticatory trauma, especially along the buccal occlusal line. Oral cancer may appear clinically as a subtle mucosal change or as an obvious mass. Oral leukoplakia is the most common premalignant oral lesion. For persistent white or erythematous oral lesions, biopsy should be performed to rule out neoplastic change or cancer. Most oral cancers are squamous cell carcinomas. Tobacco and heavy alcohol use are the principal risk factors for oral cancer. Family physicians should be able to recognize these lesions and make appropriate referrals for biopsy and treatment.
