a mature benign tumor of connective tissue, which can occur in any part of the body. Fibromas may be diffuse or encapsulated, depending on the nature of their growth. Fibroblasts are the source of fibromas, hence their other name, fibroblastomas. The symptoms and the course of a fibroma depend on the site and the rate of growth. Malignant degeneration sometimes occurs. Fibromas are treated surgically.
