경부 림프절 전이를 모방한 이소성 갑상선 증례

Abstract

Cervical neck dissection is a frequent technique during treatment for oral squamous cell carcinoma (SCC). Occasionally, specimens harvested as cervical lymph nodes reveal thyroid tissue and need differentiation with metastatic thyroid cancer and ectopic thyroid tissue. Here, we report a case of an ectopic thyroid tissue with lymphocytic thyroiditis mimicking thyroid cancer metastasis at the cervical lymph node.
