Most common metastatic tumors of the thyroid gland are squamous cell carcinoma of head and neck region, adenocarcinoma of breast and lung, malignant melanoma, and renal cell carcinoma of kidney in order of frequency. Metastasis from gastrointestinal tract to the thyroid gland rarely occurs. We experienced a case of fine needle aspiraton cytology of metastatic adenocarcinoma of both thyroid glands from the colon. Cytologic smears showed picket-fence like arrangement of nuclei of carcinoma cells and syncytial type of tissue fragments with acinar pattern on necrotic or mucoid background.
