Background: Anaplastic thyroid carcinoma (ATC) is a highly aggressive, undifferentiated carcinoma that may arise on top of normal or abnormal thyroid. Making the diagnosis by fine needle aspiration (FNA) of the thyroid with a long-standing history of multinodular goiter (MNG) is not uncommon. We report a case discussing the cytopathologic findings and the relationship with long-standing goiter and thyroid exposure to radioactive iodine treatment. Case: A 90-year-old male patient presented with a > 45-year history of MNG that was associated with thyrotoxicosis and multiple courses of radioiodine (I-131) treatment. He developed recent symptoms of dyspnea, dysphagia, neck swelling and unintentional weight loss. Computed tomography of the neck was done revealing a large MNG with retrosternal extension and calcifications. FNA was performed revealing highly anaplastic cells with a colloid background and presence of neutrophils. The diagnosis of ATC was made. The patient refused any kind of management and was discharged upon his request. He died 2 days after the procedure, and no autopsy was performed. Conclusion: ATC is an aggressive, undifferentiated thyroid carcinoma that can be diagnosed by FNA and save the patient a surgical intervention. A background of MNG and history of radioactive iodine therapy is not uncommon.
