Breast carcinomas metastatic to the jaws report of five cases

    Metastases of malignant tumors is uncommonlyseen in the oral cavity. Reported frequencies range from 1%^[1¡«4] to 8%^[5] . Metastases occur in the soft as well as in the osseous tissue of the upper and lower jaw. Bone involvement appears to be more common than soft tissue. However, the criteria used in the literature for the acceptance of a case as a definite metastasis have varied. The criteria of a metastatic case suggested by Causen and Paulsen are as follows: a) a proven rimary tumor with histologic confirmation and, whenever possible, with radiographic supportive evidence; b) maxillary, mandibular or mucosal metastasis with histologic confirmation and with radiographic evidence if the bone is involved; c) histologic correlation of the metastatic oral lesion with the primary lesion; d) when the primary lesion is anatomically near the metastasis, direct extension had to be ruled out by a wide, clear margin around the primary site with no tumor tissue present between the two foci^[6] . Causen and Paulsen found 92 carcinomas metastatic to the jaws from 1884 to 1961 which fulfilled the aforementioned criteria^[6] . McMillan and Edward, in a survey of the literature from 1966 to 1973, found an additional 166 cases^[7] . In a review of 115 cases metastatic to the jaws, Batsakis found that the most common site of primary tumor was the breast^[2] .
