Core Tip

Core Tip: Low-grade myofibroblastic sarcomas are tumors of low malignant potential; however, they are highly invasive and a high tendency to recur and metastasize to distant sites. Since only 55 cases of low-grade myofibroblastic sarcoma have been described, it is impossible to establish guidelines. As there are no specific diagnostic criteria, it is necessary to consider the occurrence of myofibroblastic sarcoma more often than reported in the literature.
