“…Nel et al 2 reported that lesions with poorly demarcated margins with cortical destruction, accompanied by clinical signs of swelling, pain, and paraesthesia in the absence of any inflammatory process, should raise suspicion for metastasis. Ho et al 3 showed that the 40 metastatic tumors to the oral soft tissues and jawbones (22 men and 18 women) included 18 cases (45%) involved the gingiva, 16 (40%) the gingiva and jawbones, 5 (12.5%) were exclusively intraosseous, and 1 affected (2.5%) the tongue. Regarding the organ of primary malignancy, the lung was the two most frequent primary site in both men ( n = 6, 27.3%) and women ( n = 5, 27.7%), followed by the colon ( n = 4, 18.2%) and kidney ( n = 3, 13.7%) in men, and colon ( n = 4, 22.2%) and breast ( n = 3, 16.6%) in women.…”
