후두암의 경부 전이로 오인된 측경부 미입 갑상샘에서 발생한 유두상 암종 1예 = Papillary Thyroid Cancer from Lateral Aberrant Thyroid Masquerading as Cervical Metastasis from Larynx Cancer: A Case Report

다국어 초록 (Multilingual Abstract)

The aberrant or ectopic thyroid in lateral neck is a rare developmental anomaly. Furthermore, the primary thyroid carcinoma arising in ectopic thyroid is extremely rare, only a few cases have been reported so far in English literature. We report a 64-year-old male with left transglottic cancer and primary papillary carcinoma from lateral aberrant thyroid in left lateral neck. Preoperatively, we diagnosed as transglottic cancer with ipsilateral neck metastasis. The patient underwent total laryngectomy, left selective neck dissection and left thyroidectomy. Finally, the patient was diagnosed as left transglottic cancer and papillary carcinoma from lateral aberrant thyroid. Surgeons should take into account a primary ectopic thyroid carcinoma arising in lateral neck may co-exist with another type of head and neck tumor.
