In addition, new entities continue to be described. The behavior and overall prognosis of these lesions is highly varied, so precise classification is required. It cannot be emphasized enough that the behavior of fibrous tumors may be difficult to predict based on traditional histologic concepts. For example, the morphologic features of some tumors, such as low-grade fibromyxoid sarcoma (LGFMS) and atypical fibroxanthoma (AFX), do not reflect their biologic behavior. For this reason, the pathologist should not attempt to predict the clinical behavior of mesenchymal tumors without a firm histologic diagnosis.
