Nodules in the thyroid have always commanded a great deal of attention because of the fear of their being cancerous. The estimated incidence of thyroid nodules in children and young adults is about 0.22 to 1.8 percent. According to different epidemiological data, about 10 to 35 percent of thyroid cancers occur in the first two decades. The present study based on microscopic review of tissue sli...
BACKGROUND Ectopic (accessory) adrenocortical tissue, also known as adrenal rests, is a developmental abnormality of the adrenal gland. The most common ectopic site is in close proximity to the adrenal glands and along the path of descent or migration of the gonads because of the close spatial relationship between the adrenocortical primordium and gonadal blastema during embryogenesis. Ectopic ...
Classification The major morphological classifications (WHO/ AFIP; modified Mainz classification, and the Heidelberg classification) discriminate eight sub-types of renal cell tumors related to the basic cell types of the nephron from which they are derived, and in line with the genetic facts as presently understood: 1) metanephric adenoma and metanephric adenofibroma, 2) papillary adenoma, 3) ...
Background & Aim: Anaplastic thyroid carcinoma (ATC) is an uncommon malignancy of the thyroid .with poor prognosis and 2 to 6 month of survival time. The aim of this study was to explore the effect of curcumin on bioavailability and expression of p21 and Bcl-2 genes in human anaplastic thyroid carcinoma cell line (SW-1736). Methods: In this study, human anaplastic thyroid carcinoma (SW-1736) c...
The present case report concerns a 42-year-old female who referred with an enlargement of right lobe of thyroid gland since 6 months ago. Subtotal thyroidectomy specimen grossly revealed white-colored and poorly-demarcated nodule with papillary growth pattern. Microscopic examination mostly exhibited papillae lined by tall columnar cells containing pseudostratified nuclei which rese...
Adrenal and thyroid hormones are essential for the regulation of intrauterine homeostasis, and for the timely differentiation and maturation of fetal organs. These hormones play complex roles during fetal life, and are believed to underlie the cellular communication that coordinates maternal-fetal interactions. They serve to modulate the functional adaptation for extrauterine life during the pe...
OBJECTIVE Adrenal masses usually represent benign and nonfunctional adrenal adenomas; however, primary or metastatic malignancy should also be considered. Discovery of an adrenal mass needs further evaluation in order to exclude malignancy and hormonal secretion. We present a rare case of a possibly primary adrenal malignant melanoma with imaging and biochemical features of a pheochromocytoma. ...
Metastatic spread of differentiated thyroid cancer to genitourinary organs is rare. Synchronous presentation of renal and adrenal thyroid metastasis is even less common, this case being only the 3rd reported. We describe a case of a 60-year-old male with oligometastatic thyroid cancer, where adrenal and renal metastases were the only extracervical sites of disease and triggered the patient's pr...
introduction:differentiated thyroid carcinoma (dtc) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (tg), diagnostic iodine-131 whole body scan (dxwbs) and sonography. some patients with undetectable tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. methods: in this study, we e...
