This study was designed to explore differences in the ultrasonographic characteristics of medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC). This study included 35 cases of MTC and 96 cases of PTC that were surgically and pathologically confirmed. Preoperative ultrasound images were retrospectively reviewed by two physicians (with 5 years' experience in thyroid ultrasound)...

BACKGROUND Clinically evident cardiac metastases from malignant neoplasms are uncommon. The frequency of thyroid metastasis to the heart is very low. To our knowledge, over the last 20 years only a few cases have been reported in the entire literature. Metastatic cardiac involvement occurs most often during the terminal stage. PATIENTS We present three cases of anaplastic thyroid cancer with ...

The presence of chronic lymphocytic leukaemia (CLL) cells in the thyroid gland is most likely due to a secondary involvement by a systemic disease. The reported incidence of CLL involving the thyroid is extremely low, representing about 3-4% of all thyroid lymphoproliferative neoplasm. We report a rare case of CLL presenting initially in the thyroid gland. Systemic disease was detected as a res...

Thyroid carcinoma with distant metastases at initial presentation, is uncommon. Skull metastases occur very rarely, with a reported incidence of 2.5-5.8%. Here we report two cases of follicular thyroid cancer with skull involvement, and describe the diagnostic and therapeutic approach to metastatic thyroid cancer. We present the cases of a 70-year-old female and a 74-year-old female who present...

INVESTIGATIONS of seasonal changes in thyroid histology in wild birds have shown that increases in activity occur in the period preceding and during the annual molt (Davis and Davis, 1954; Assenmacher, 1958; Voitkevich, 1966) and in response to low temperature (Wilson and Farner, 1960; Kendeigh and Wallin, 1966). Involvement of th'e avian thyroid in migration and reproduction has also been sugg...

Granular cell tumor presenting as a thyroid mass is very rare. It may arise from the thyroid gland or from the tissues/organs adjacent to the thyroid gland. It may cytologically mimick other common thyroid tumors. The accurate evaluation of these tumors may be important for management. We describe a granular cell tumor arising from the tissue adjacent to the thyroid gland and with multiple orga...

BACKGROUND/AIMS The aim of the present study was to evaluate the relationship between thyroid hormone levels and infarct severity in patients with ST-elevation myocardial infarction (STEMI). METHODS We retrospectively reviewed thyroid hormone levels, infarct severity, and the extent of transmurality in 40 STEMI patients evaluated via contrast-enhanced cardiac magnetic resonance imaging. RES...

BACKGROUND The study was designed to explore the regular patterns of level V lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC), and to indicate whether level V should be included in the management of lateral neck dissection when treating PTC. METHODS This retrospective study consisted of 330 patients diagnosed with PTC from January 1994 to July 2009 who underwent an operation t...
