We experienced a rare case of thyroid metastasis from cervical cancer.

The p16 staining was helpful to diagnose metastatic cervical cancer.

Palliative Surgical resection is useful to secure the airway and digestive tract.

Abstract

There have been very few reports of thyroid metastasis from cervical carcinoma. This article reports a case of metastasis from cervical carcinoma. A 69-year-old woman with a history of cervical cancer presented to our department with right cervical swelling. She had suffered from paralysis of the left recurrent laryngeal nerve after undergoing left hemithyroidectomy 16 years ago. Computed Tomography (CT) and magnetic resonance imaging scans revealed a right thyroid tumor with bilateral enlargement of the cervical lymph nodes. Fluorodeoxyglucose positron emission tomography/CT imaging revealed high uptake in the right thyroid tumor, cervical lymph nodes, and right iliac bone. Fine-needle aspiration cytology revealed atypical epithelial cells with a high nuclear/cell ratio and hyperchromatic nuclei, which resembled cervical cancer cells. Given the risk of airway obstruction and dysphagia, the patient underwent tracheostomy, right hemithyroidectomy, and neck dissection for preserving the quality of life. Pathological examination revealed normal thyroid tissue with p16-positive atypical epithelial cells, which suggested thyroid metastasis from the cervical cancer. The patient has remained alive without any symptoms for 5 postoperative months.
