Metastasis of Papillary Thyroid Carcinoma to the Maxillary Sinus: Case Report and Review of the Literature

Abstract: Metastasis of the thyroid carcinoma to the paranasal sinuses is rarely reported. Among these sinuses, metastasis to the maxillary sinus alone has been reported only in a few cases. This is the first reported case in a 76-year-old woman with papillary thyroid carcinoma metastasizing to the maxillary sinus alone and resected through endoscopic sinonasal surgery. When patients have sinus lesions and a history of malignancy, metastasis should be included in the differential diagnosis. If they have an isolated meta… Show more

“…The third case was reported by Shimmura et al (2020), [15] who reported a 76-year-old woman with a complaint of right intermittent epistaxis that started two years ago. She had a medical history of PTC for 8 years and had undergone total thyroidectomy, neck dissection twice, stereotactic radiation therapy for metastases to the cervical vertebrae and parapharyngeal space, and TDRI.…”

“…[7][8][9][10][11][12][13] While searching for the search terms "papillary thyroid carcinoma +maxillary metastasis" within the same period, three publications were retrieved. [10,14,15] Papillary and follicular thyroid carcinoma (FTC) account for 80% and 7% of all thyroid carcinomas, respectively. They differ histologically from the rarer type of poorly differentiated and undifferentiated anaplastic carcinomas, which together account for 5% of thyroid carcinomas, as well as from medullary carcinoma of the thyroid, which arises from parafollicular C cells.…”

“…Metastasis is found at the time of diagnosis (de novo metastasis) of breast cancer in 5%–10% of patients 2. Sino-orbital metastasis of breast cancer is extremely rare and accounts for 1.5% of all paranasal sinus carcinomas 5. Here, we report a rare and unique case of a patient presenting with a sino-orbital mass as a presenting sign of advanced breast cancer.…”
