Late Pancreatic Metastasis From Papillary Thyroid Carcinoma Diagnosed by Endoscopic Ultrasound-Guided Tissue Acquisition

If pancreatic lesions are discovered during regular follow-up of patients who have previously been treated for papillary thyroid carcinoma, pancreatic metastasis must be considered, and imaging procedures other than whole-body iodine scintigraphy are required. Histopathology and iodine avidity will define the best therapeutic strategy. Radioactive iodine ablation should be considered for iodine-avid metastases, and surgery or tyrosine kinase inhibitors are promising options for non-iodine-avid lesions.
