A Suspected Case of Cervical Lymph Node Metastasis from Adenomatous Goiter

Abstract

Thyroid tissue in the cervical lymph nodes without a history of malignant thyroid tumor is rarely encountered, and when detected, it is usually interpreted as ectopic thyroid tissue. We report a case in which thyroid tissue was found in numerous cervical lymph nodes. Thyroid cancer and cervical lymph node metastasis were suspected and hemithyroidectomy with neck dissection was performed. No histopathological evidence of malignancy was found in either the excised thyroid gland or lymph nodes.

Finally, we diagnosed the case as adenomatous goiter with metastasis to the cervical lymph nodes.

We believe that the patient needs to be closely followed up for any evidence of malignancy, and that if the patient develops further lymphadenopathy, etc., in addition to neck dissection, it would also be necessary to consider completion total thyroidectomy and iodine therapy.
