Summary
Metastatic breast carcinoma rarely affects the paranasal sinuses, presenting as a sinonasal mass. This case highlights a late metastasis to the maxilla, emphasizing the need for vigilance in cancer surveillance.
Area of Science:
- Oncology
- Otorhinolaryngology
- Pathology
Background:
- Metastatic tumors to the paranasal sinuses are exceedingly rare occurrences in clinical practice.
- Breast carcinoma, a common malignancy, typically metastasizes to distant organs like bone, liver, lung, and brain.
Observation:
- This report details a unique case of breast carcinoma metastasizing to the right maxilla, five years post-radical mastectomy.
- The metastasis manifested as a primary sinonasal mass, mimicking a new localized tumor.
- Histopathologic and immunohistochemical examinations confirmed the metastatic origin from breast carcinoma.
Findings:
- The study confirms the rare phenomenon of breast cancer metastasis to the sinonasal region, specifically the maxilla.
- The metastatic lesion presented as a de novo sinonasal mass, complicating initial diagnosis.
- Despite diagnostic confirmation, the patient succumbed to tumor bleeding before treatment initiation.
Implications:
- This case underscores the importance of considering unusual metastatic sites in patients with a history of breast cancer.
- It highlights the diagnostic challenges posed by sinonasal masses in cancer survivors.
- Further research into the mechanisms and clinical behavior of rare cancer metastases is warranted.
