Uncommon Metastasis to Thyroid Gland Presenting as a Thyroid Nodule
並列摘要
Introduction: Metastatic spread to the thyroid is not common in spite of the fact that it has a high vascularity. It is a rare situation especially in an individual without a prior history of malignancy. Thyroid gland is not the common site of metastasis in case of an esophageal malignancy. Case Report: A 60-year-old female was presented to our hospital with a solitary thyroid nodule involving the left lobe with cervical lymphadenopathy. There were no clinical features of hypothyroidism or hyperthyroidism. However, laboratory investigations revealed hypothyroid state. Patient was started on thyroxine 100 mg daily. Fine needle aspiration cytology (FNAC) revealed the presence of squamous cell deposits. On further investigating by upper gastrointestinal endoscopy, an ulcerative growth was detected 20 cm from the incisors. Biopsy from the growth confirmed the diagnosis of squamous cell carcinoma of the esophagus. Patient was treated with chemoradiation. Conclusion: All atypical neck masses have to be thoroughly investigated as all neck masses may not be related to primary thyroid conditions. This will result in avoiding unnecessary thyroidectomies instead of treating primary pathology.
