Fibromas are benign tumors that are composed of fibrous or connective tissue. They can grow in all organs, arising from mesenchyme tissue. The term “fibroblastic” or “fibromatous” is used to describe tumors of the fibrous connective tissue. When the term fibroma is used without modifier, it is usually considered benign, with the term fibrosarcoma reserved for malignant tumors.
Soft fibromas are the most common fibrous lesions of the skin. Lesions are most commonly located on the neck and the intertriginous areas of the axilla and groin, but can be found scattered throughout the skin.
