title: Mandibular Metastasis of a Signet Ring Cell Carcinoma of the Breast in a Patient who Underwent Bilateral Mastectomy more than 25 Years Earlier.
abstract: SUMMARY: BACKGROUND: Metastatic tumors account for less than 1% of all malignant tumors occurring in the oral cavity. CASE REPORT: The clinical case of a 94-year-old patient with a mandibular tumor is reported here. The patient had undergone bilateral mastectomy more than 25 years before. An immunohistochemical study found hormone receptors in signet ring cells, suggesting a diagnosis of breast cancer metastasis. CONCLUSION: Immunohistochemical diagnosis and antineoplastic hormone therapy is the cornerstone in the management of this clinical case.
