Asymptomatic, nonulcerated, freely movable nodule in the anterior floor of the mouth.
Small, localized aggregations of lymphoid tissue can occur commonly in the oral cavity, especially in the soft palate, the floor of the mouth, and the ventral surface of the tongue. They normally appear clinically as asymptomatic, small, soft, pink, and discrete swellings situated immediately beneath the surface epithelium. Chronic irritation may cause the tissue to enlarge and become symptomatic. Clinicians should be aware of the existence of these rather common oral lesions and include them in a differential consideration of small, freely movable, nonulcerated subepithelial swellings in the oral cavity. Microscopic examination is indicated to rule out a more serious disease, especially a developing neoplastic process.
