RESUMO
We report a case of concurrent medullary and papillary microcarcinoma of the thyroid gland. We also found a nonrecurrent laryngeal nerve in the right side. The nonrecurrent laryngeal nerve is an unusual and potentially serious postoperative complication. A 36-year-old female underwent right hemithyroidectomy for follicular neoplasm, diagnosed by fine needle aspiration biopsy. The histopathologic report demonstrated a medullary microcarcinoma in one nodule with lymph node metastasis and papillary thyroid micocarcinoma in other two lesions. Incidentally, we also found an aberrant right subclavian artery by computed tomography and confirmed nonrecurrent laryngeal nerve in surgery. We performed completion thyroidectomy with central and lateral neck lymph nodes dissection. We could not find any more carcinoma on the pathologic examination. The patient was given radioactive iodine therapy for remnant thyroid ablation. The patient is scheduled to check serum calcitonin and CEA level every 3 months.
