Sarcomas are rare tumors originating from soft tissue or bone. Diagnosis and treatment of sarcomas should be performed at specialized sarcoma centers, where patients are evaluated at a multidisciplinary tumor conference. We present a case where sarcoma was suspected from magnetic resonance imaging (MRI), but histology revealed a metastasis from thyroid carcinoma, although the patient had no pre...

ectopic thyroid tissue (ett) is a rare entity and a challenging differential diagnosis. this is a report of a case of a mediastinal mass that was found to be an ectopic mediastinal thyroid tissue, in a 77-year-old woman who was admitted to our hospital for breast cancer management. the mediastinal mass was identified in the postsurgical computed tomography (ct) scan of the chest and was suspect...

BACKGROUND Clinically detectable thyroid nodules occur in up to 4% of the population in the United States. With ultrasound, nodules may be found in up to 50% of those over 50 years of age. METHODS The author reviews his own experience as well as that of others to define a sound clinical approach to the differential diagnosis and detection of thyroid cancer. RESULTS Prior neck irradiation is...

OBJECTIVE To validate a new risk stratification system for thyroid nodules, the Korean Thyroid Imaging Reporting and Data System (K-TIRADS), using a prospective design. MATERIALS AND METHODS From June 2013 to May 2015, 902 thyroid nodules were enrolled from four institutions. The type and predictive value of ultrasonography (US) predictors were analyzed according to the combination of the sol...

Aim: Thyroid scan with sestamibi is used for evaluation of thyroid nodules with the aim of increasing specificity before surgery. In this study we evaluated the role of Sestamibi thyroid scan in candidates for thyroid surgery. Methods and patients: During two years, 37 patients were studied with solitary thyroid nodules, referred for thyroid surgery due to malignant or suspicious FNAB res...

Background and Objectives: Lesions of the thyroid and breast represent the two commonest sources of frozen section in Kuwait. This study investigates the value of intraoperative cytology (IC), preoperative fine needle aspiration cytology (FNAC) and intraoperative frozen section (FS), in improving the diagnostic accuracy of such lesions. Material: Thirty-one breast masses and 45 thyroid lesions ...

Objective: To evaluate the contribution of 131I scintigraphy and ultrasonography to the prediction of malignancy in thyroid nodules with indeterminate cytology in euthyroid patients. Subjects and methods: The sample consisted of 102 patients with thyroid nodules, submitted to FNAC and presenting an indeterminate cytological diagnosis (follicular neoplasm). Results: Malignancy was observed in 19...

Most clinicians assume that a thyroid mass which appears to be malignant is most likely a tumour arising from thyroid cells. We present a case where the thyroid malignancy was associated with a degree of systemic clinical and biochemical disturbance which suggested alternative diagnoses, and in which fine-needle aspiration revealed that the patient had a thyroid lymphoma. Gastric biopsy showed ...

CONTEXT Thyroid cancer incidence has increased significantly during the past decades and is the most common type of endocrine malignancy. Many factors in thyroid cancers were studied as independent predictors of a poor prognosis. OBJECTIVE The objective of the study was to evaluate survivin expression - BIRC5 and its splice variants: survivin delta Ex3 and survivin 2B in benign and malignant ...

An analysis of management of 546 cases of solitary thyroid nodules in an endemic area is presented. None of the evaluating procedures could effectively isolate benign from malignant disease. Of 508 cases considered clinically to be benign, 42 harboured malignancy on histological examination whereas of the 38 cases suspected clinically to be malignant, 21 were histologically benign. 131I-Thyroid...
