What is a characteristic feature of a fibroma present in the oral cavity?

A fibroma in the oral cavity is typically characterized by a firm, nodular mass. This firmness arises from the proliferation of fibroblasts and dense collagen in the lesion, giving it a solid texture. Fibromas are benign tumors that usually present as a well-defined, smooth, and nodular growth that can be found on various oral tissues, including the gums and tongue. Their composition is primarily connective tissue, which contributes to the nodular firm appearance.

The feature of rapid growth is not typical for fibromas, as these lesions tend to grow slowly and are often asymptomatic. Irregular surface texture and pedunculated appearance are also not characteristic of fibromas; rather, they are smoother and more defined in structure. Understanding these distinctive traits is crucial for accurate diagnosis and differentiation from other oral lesions.
