title: Synchronous thyroid metastasis from lung adenocarcinoma.
abstract: Metastases from other primary malignancies to the thyroid gland are clinically uncommon, far less frequent than any malignant primary neoplasm, mostly affecting elderly patients. Recent autopsy studies have shown that metastases to the tyroid is relatively common, with a prevalence of of 1,9-24%. We present a case of a man (72 years old) with lung cancer and synchronous metastasis to thyroid gland. Typically the interval between the diagnosis of the primary tumor and the detection of thyroid metastasis is from one month to 26 years. Clinical manifestation of thyroid metastases are rare
