Low-Grade Myofibroblastic Sarcoma of the Chest Wall: A Rare Tumor Entity

Abstract Low-grade myofibroblastic sarcoma of the chest wall is a rare tumor entity. We report a case in a 58-year-old patient in whom en-bloc resection of the tumor and reconstruction of the chest wall was performed. Initially no further adjuvant treatment was established.
