Intrathyroid metastasis presenting as a solitary thyroid nodule: an unusual case of clinically silent lung cancer.
Metastases in the thyroid gland are very rare. Carcinoma lung is one of the tumours, which may metastasize to the thyroid. We report a 60-year-old lady with intrathyroid metastasis presenting as a solitary thyroid nodule. Fine needle aspiration cytology from the nodule showed features of metastatic adenocarcinoma. Further detail evaluation revealed primary lung adenocarcinoma with secondaries to adrenals, retroperitoneal and bilateral axillary nodes. This report emphasizes this unusual clinical presentation of carcinoma lung with wide spread secondaries; and a solitary thyroid nodule can be a presenting complain of a metastatic disease.
