Multiple thyroid nodules in the lung: XXXX or ectopia?

BACKGROUND: Intrapulmonary thyroid tissue with no malignant history of the thyroid gland is extremely rare. Usually, it is interpreted as @entity16490 . Here we describe a case of bilateral pulmonary thyroid nodules with a history of multinodular @entity5651 . HISTORY: A 37-year-old female had recurrent multinodular @entity5651 and showed bilateral pulmonary nodules on CT scan. Video-assisted thoracic surgery (VATS) was performed for the largest nodule biopsy. Pathological and molecular examinations were done after biopsy, and both were shown the characters of benign thyroid tissues. To eliminate the possibility of @entity259 metastases, total thyroidectomy with modified radical neck dissection was performed, and there were no malignant pathological findings. After surgery, this @entity1 accepted adjuvant radiometabolic treatment for ablation of the remaining intrapulmonary nodules. Her thyroglobulin level decreased to an undetectable level, and she has currently survived for 24  months after surgery. CLINICAL SIGNIFICANCE: In this case, @entity16490 and metastasizing @entity259 should both be considered, but the metastatic pattern and benign pathological characters were inconsistent with any of the corresponding diagnosis. Ultimately, this @entity1 accepted postoperative treatment of @entity259 @entity3 . CONCLUSIONS: This is a rare @entity1374 with malignant behavior but no pathological evidence. Careful diagnosis and postoprative follow-up should be carried out whenever such nodules are encountered in clinical practice.
