“…Fibrosarcoma usually presents as a slow‐growing, sometimes painful, mass with other symptoms related to its location (25, 27, 139). The majority of the cases arise in the extremities and in the trunk, but 10% of cases occur in the head and neck, where they can occur in almost any site, including the oral cavity (8, 18, 64, 69, 75, 82, 105, 150).
