Rare Presentation of Metastatic Papillary Thyroid Carcinoma with Cribiform Type in Pelvic Bones

The papillary thyroid carcinoma is the most common endocrinologic neoplasm. Only the 10% of all patients have metastasis, however as high as 50% of all will have metastasis at the moment of the diagnosis. Lung and bone being the primary organs affected, only 5% are in other areas of the body. The Gold Standard for the diagnosis is the high-resolution ultrasound of the thyroid complementing with fine needle puncture-aspiration assessment, which help us in the decision making.
