Abstract

Abstract: Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Due to their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. In this article we present a rare, unusual & exceptional case of left maxillary mass which on further evaluation leading to diagnosis of left breast carcinoma with metastasis to isolated left maxillary bone. Sixty five year old postmenopausal woman of low socioeconomic status with good performance status presented with a 3 months history of progressive pain and swelling in the left maxillary region. Fine Needle Aspiration Cytology (FNAC) from the maxillary mass shows invasive ductal carcinoma. On further clinical, radiographic, and histopathological examination findings from the breast lesion confirmed the diagnosis of hormone receptor positive metastatic breast carcinoma. In view of painful metastatic maxillary lesion with breast disease she was managed with a palliative radiotherapy to the maxillary lesion and palliative chemotherapy with Doxorubicin-Cyclophosphamide and bhisphosphonate-Zolendronic acid. Patient responded very well to palliative radiotherapy and chemotherapy, in view of hormone receptor positive breast cancer, now she is on Tab. Anastrazole 1 mg once a day along with monthly Zolendronic acid injection since last 13 months without any symptoms of disease evolution. A high index of clinical thought of metastatic cancer to maxilla is necessary when evaluating patients who complain of maxillary pain and swelling without a history of pain or swelling in the head and neck & non-head and neck region. To the best of our knowledge, this is the first reported case of a metastatic isolated solitary maxillary bone metastasis presenting as an early sign of breast cancer.
