What type of tissue is irritation fibroma primarily composed of?

Irritation fibroma is primarily composed of dense fibrous connective tissue. This type of tissue is characterized by a high concentration of collagen fibers, which provide strength and support. The fibrous nature of irritation fibromas results from their formation in response to chronic irritation or trauma, leading to a reactive proliferation of the connective tissue.

The dense arrangement of collagen fibers is crucial because it helps to withstand mechanical stress that may occur in areas subjected to repeated irritation. This distinct composition distinguishes irritation fibromas from other tissue types. For instance, loose connective tissue, which is more flexible and provides cushioning, is not involved in the formation of irritation fibromas. Similarly, epithelial tissue, which makes up the skin and lining of organs, does not contribute to the fibromatous structure, nor does adipose tissue, which primarily consists of fat cells.
