Metastatic medullary thyroid carcinoma in liver diagnosis by aspiration cytology.
A case of metastatic medullary thyroid carcinoma (MTC) to the liver of a patient with multiple endocrine neoplasia (MEN) Type IIb was suggested by percutaneous fine-needle aspiration cytology and confirmed by histology and immunohistochemistry. The cytologic presentation of this unusual thyroid cancer in liver has not been previously reported. We report such a case and discuss its differential diagnosis from other metastatic tumors of the liver.
