A case of different thyroid cancer is reported in detail, showing unusual behaviour both clinically and bioptically. The patient suffered from severe hyperthyroidism, with a scintigraphic finding of independent thyroid adenoma and simultaneous function in pelvic mass proved to be a metastasis of follicular thyroid cancer. Bioptical finding confirmed the aspiration biopsy conclusion that the independently functioning thyroid nodule had been in fact a follicular thyroid cancer. Microscopically, a transition of the usual type of follicular thyroid cancer to solid cancer consisting of water-clear cells was found. Thyroidectomy led to enhancement of uptake in pelvic metastasis but the general condition deteriorated rapidly leading to death by pulmonary embolism. The problem is discussed with regard to the development of hyperthyroidism in thyroid cancer.

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. Exogenous sublinical hyperthyroidism is a thyroid metabolic state caused by L-thyroxine administration. Endogenous subclinical hyperthyroidism is a thyroid metabolic state in patients with autonomously functioning thyroid nodule or multinodular goiter, various forms of thyroiditis, in areas with endemic goiter and particularly in elderly subjects. Endogenous subclinical hyperthyroidism is currently the subject of numerous studies and it yet remains controversial particularly as it relates to its treatment and to cardiovascular impact nevertheless established effects have been demonstrated. Recently, acute myocardial infarction without significant coronary stenoses and recurrent acute pulmonary embolism have been reported associated with subclinical hyperthyroidism without L-thyroxine administration. So, it is very important to recognize and to treat promptly also endogenous subclinical hyperthyroidism.

Upper extremity deep vein thrombosis (UEDVT) is a life threatening rare condition. Among the patients with UEDVT, internal jugular vein is accepted as uncommon thrombosis. Since internal jugular vein thrombosis (IJVT) is mostly underdiagnosed, a great attention is needed to diagnose the disease. A 75-year-old woman with history of dyspnea on exertion (DOE), weight loss and anorexia with the stable vital sign and right-sided cervical adenopathy with suspected thyroid nodule was admitted. One day after admission, sudden dyspnea was occurring with unstable vital sign and hypotension. Chest X-ray showed a bilateral pleural effusion. Pleural tap was exudative, CT scan showed bilateral pulmonary emboli. CT scan of the neck showed right-sided cervical adenopathy, heterogeneous thyroid and internal jugular vein thrombosis concomitant with superior thyroid vein thrombosis. The patient was treated with thrombolytic agent and enoxaparin followed by warfarin. Thyroid FNA revealed papillary thyroid carcinoma that followed by total thyroidectomy, histopathological examination verified papillary thyroid carcinoma. Although lower extremity DVT is the main cause of pulmonary emboli, but IJVT may be proceed by pulmonary embolism. Due to fatal outcome of pulmonary emboli in IJVT, color duplex sonography, is recommended in documented tumors or suspected history of malignancy.
