Introduction: We report a case of a 64-year old man with a history of colon carcinoma. He underwent fine-needle aspiration by CytoFoam-core and diagnosis of metastatic colon cancer to the thyroid gland. Case presentation: In this case report, a solid thyroid nodule in the right lobe of a 64-year-old male was aspirated. The cytological smears showed a small group of atypical cells with the obvi...

introduction: radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs are important to weigh the risks and benefits of this method. the aim of this study is to measure the absorbed doses of important organs by mcnp (monte carlo n particle) simulation and comparing the results of different method...

dendrostellera lessertii (thymelaeaceae) is a toxic plant that grows in parts of iran. the anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-hk), have been established using several cancer cell lines. methods: in a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...

introduction: there is a limited number of case reports published in the past decade confirming the radio-iodine presence in the tear. these observations as well as reported cases of salivary and lacrimal gland dysfunction after radioiodine therapy stimulated investigators to clarify whether lacrimal gland function can be affected post-radioiodine therapy. hence we planned a historical cohort s...

background and objective: hypothyroidism is a known consequence of the external beam radiotherapy to the neck encompassing the thyroid gland for over 40 years. the aim of this study was to find out the incidence of hypothyroidism in patients with head and neck cancer treated with radiotherapy, when radiation portals included whole of the thyroid gland. materials and methods: this prospective no...

objective(s): we investigated a frequency of lower extremity uptake on the radioactive iodine (rai) whole body scan (wbs) after rai treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. methods: this retrospective study included 170 patients with thyroid cancer, undergoing rai treatment. overall, 99r (58%) an...

Medical records of 228 patients who had undergone thyroid surgery were studied. There were 179 females and 49 males with mean age of 33-8 years. Pre-op. diagnosis was cold nodule in 4. 4 %. Pathology diagnosis was simple goiter in 54%, adenoma in 23%, thyroid cancer in 15% and colloid cyst in 5.3% of the patients. Among carcinomas 68% were papillary, 29% follicular and 3% medullary. There were1...

Background: Thyroid carcinoma is the most common malignancy of the endocrine system. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. Thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. As a result of diagnostic methods improvement, p...

We studied the clinical, radioisotopic, and pathologic characteristics and the incidence of cancer in clinically solitary cold nodules of the thyroid in an iodinedeficient area. The study included retrospective analysis of 765 patients who underwent thyroidectomy for a clinically single cold nodule in a ten-year period. We compared the pathological findings with clinical data. In pathologic...
