Abstract

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human malignancies and constitutes approximately 1.6-5% of the malignant neoplasms of the thyroid gland. ATC usually manifests itself with the local symptoms due to a rapidly enlarging thyroid mass, and as other thyroid cancers, has only seldom been reported to cause thyrotoxicosis. Up to now only 9 cases of ATC with concomitant thyrotoxicosis have been described. We report a rare case of a 66-year-old woman, who had had the preexisting large, euthyroid multinodular goiter for almost 50 years. She was consulted by a doctor because of a 4-week history of thyrotoxicosis, symptoms of the congestive heart failure and a rapid increase in the size of the goiter. Thyroid hormone levels were consistent with a hyperthyroid state. The fine-needle aspiration biopsy confirmed a diagnosis of the anaplastic thyroid carcinoma, the small cells variant. The 99m Tc-pertechnetate scintigraphy visualized non-homogenous tracer distribution with hot nodules. She was given a doxorubicin (20 mg/week) and required the continuous antithyroid treatment. The patient died a one year after the first symptoms of the disease occurred. The association between ATC and a thyrotoxic state is very ra...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
