Fibrous Histiocytoma is a type of benign tumor that typically arises in the skin or soft tissues. It is composed of a mixture of fibrous tissue and histiocytes, which are a type of immune cell. These tumors often appear as firm, raised nodules and can vary in size. They are most commonly found in young adults and may occur after trauma or injury to the skin. While Fibrous Histiocytoma is generally non-cancerous, it can sometimes be mistaken for more serious conditions. Diagnosis usually involves a physical examination and may require a biopsy to confirm the presence of the tumor. Treatment often includes surgical removal, especially if the tumor is causing discomfort or cosmetic concerns.
