OBJECTIVES/HYPOTHESIS The objective was to determine clinical features and clinical outcomes for pediatric thyroid carcinoma. STUDY DESIGN Cross-sectional analysis of national cancer database. METHODS The Surveillance, Epidemiology, and End Results database (1988-2000) was surveyed, extracting all cases of pediatric thyroid carcinoma. Clinical features including age, gender, tumor type, tum...
Skull base metastasis from differentiated thyroid carcinoma including follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) is a rare clinical entity. Eighteen FTC cases and 10 PTC cases showing skull base metastasis have been reported. The most common symptom of skull base metastasis from FTC and PTC is cranial nerve dysfunction. Bone destruction and local invasion to the su...
Misfolding and aggregation of amyloid peptides are critical pathological events in numerous protein misfolding diseases (PMDs), such as Alzheimer’s disease (AD), type II diabetes (T2D), medullary thyroid carcinoma (MTC)....
Background Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side o...
Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1-3% of all ectopic thyroid tissue is located in the lateral n...
twenty-one patients with medullary thyroid carcinoma were studied prospectively with tc-99m (v) dmsa after surgery. pentavalent dmsa scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. finally, seven patients with surgical or other imaging documentation were selected for this paper. most of these patients were asymptomatic. six patients had hypercalcitonemia and se...
We herein reported a primary pulmonary papillary carcinoma with colloid-like luminal content in the glandular cavity and classic nuclear features such as pseudo-inclusions, intranuclear grooves in the tumor cell nuclei and ground glass nuclei which closely mimics papillary thyroid carcinoma. Meanwhile, lymph node in the left pulmonary hilum was involved and showed similar features to the primar...
A 68-year-old woman with solid/trabecular follicular thyroid carcinoma inside of an autonomously functioning thyroid nodule is described in this paper. The patient was referred to our clinic for swelling of the neck and an increased pulse rate. Ultrasonography showed a slightly hypoechoic nodule in the right lobe of the thyroid. Despite suppressed TSH levels, the (99m)Tc-pertechnetate scan show...
thyroid cancer is the most common endocrine malignancy. this study surveys the pathologic characteristics of thyroid cancerin mashhad and study of papillary carcinoma in more detail. in this retrospective study, 108 out of 197 cases of thyroid cancer were papillary in type (55%), with female to male ratio of 1.91 which is lower than current reports. the age at the time of diagnosis ranged from ...
Although elevated c-myc expression seems to be related to an unfavorable prognosis of human thyroid neoplasias, the role of c-myc overexpression in the process of thyroid carcinogenesis is still unknown. We analyzed c-myc expression in 7 human thyroid carcinoma cell lines, originating from different histotypes, and in 50 fresh thyroid tumors and found a higher level of c-myc mRNA in all the thy...
