In Denmark, the annual incidence of paranasal malignancies is approximately 60, often presenting with symptoms from growth into neighbouring structures. This case report is of a primary neuroendocrine paranasal tumour with distant metastases in an 81-year-old woman. Following a tooth extraction, the patient developed left side proptosis. A CT-scan showed a tumour of left ethmoidal sinus with local spreading to orbita, skull base, and contralateral ethmoid, and following scans visualised lymph node infiltration and multiple metastases. Paranasal malignancies can present with symptoms from teeth in upper jaw.
