A rare case report of metastatic breast carcinoma in the Oral mucosa and literature review

Abstract

Metastatic lesions in the oral cavity are rare, representing 1-3% of all malignant neoplasia in this region. Within this rate, there is a distribution in the literature among affected tissue, gender, and the origin of the metastases. The minority of the presented cases are describing metastatic lesions of breast cancer located in the oral cavity soft tissues in female patients. Thus, we are presenting a case of a 47-year-old female patient who has reached the final stage of breast cancer with systematically spread metastatic disease, including lesions in the oral soft tissues. The exophytic growth of these tumors was causing difficulties in essential oral functions, such as mastication and articulation. For this reason, a palliative surgical excision of the metastases was performed, resulting in a significant improvement of the patient’s quality of life during her final palliative care treatment. Metastatic lesions in the oral cavity are a rarity and can appear within an already known systematic disease. Furthermore, during the final stage of breast cancer, it is highly uncommon for lesions to spread in the oral mucosa; however, the latter should be considered as a pos- sible metastatic location during clinical examination and tumor staging.
