The nodules are observed in more than 50% of patients with thyroid pathology; the incidence of nodules can reach % in endemic regions. Thyroid lesions include both colloid nodules and tumors. The goiter was described in history for long time. Many luminaries suffered from it. The enlargement of thyroid is known as goiter, it can arise from various causes and each has separate aetiopathogenesis and treatment. As an overview for the book, this chapter delves into each aspect, whereas the details are in separate chapter.
The Nile valley of Egypt is characteristically an endemic area of iodine deficiency goiter [21, 22]. The endemic nature of the region casts certain features on the thyroid cancer profile in our locality. At our University, follicular carcinoma constituted % of thyroid cancer patients. Papillary carcinoma remained the most common variant Author: Osama Hussein. Endocrine System Pathology_ Ppt Lecture Series (5 in 1) 1. Pathology of Endocrine System Photos: The surgeon in this photo is transfusing donor islet cells into a diabetic patient. The islet cells may take residence in the pancreas and secrete insulin for the patient. Note the new islet cells in the right-hand photo.
Congenital iodine deficiency syndrome is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone (hypothyroidism) often caused by insufficient dietary iodine during pregnancy. It is one cause of underactive thyroid function at birth, called congenital hypothyroidism, and also referred to as lty: Endocrinology.

Endemic Goiter, also known as Multinodular Goiter, is the presence of a goiter caused by nutritional deficiency of Iodine. As table salt is now supplemented with iodine, endemic goiter is almost never observed except in on some occasions in developing countries.
MNG is endemic in regions with low iodine level in the soil, such as countries in the mountainous areas in South-East Asia, Latin America and Central Africa. The World Health Organization reported a worldwide iodine deficiency rate of 9. 8 – 9% and total goiter prevalence of 4.
Cited by: 5. This village was severely iodine deficient with 11% prevalence of endemic cretinism. The diet included available main crops (maize, wheat), vegetables, and water from the area with an iodine content of µg/kg. After the dam had received the diet for 4 months, there was obvious neonatal goiter, Cited by: Immunological features of endemic goiter.
Abstract. Some immune aspects of simple endemic goiter have been studied through a comparison of IgG, IgA, IgM, k and λ chains, and C3 and C4 in the peripheral blood of 59 patients operated on for goiter and the peripheral blood of 49 normal controls.
The median IgM was lower in the goiter by: 8. A retrospective morphological and immunohistochemical study of 21 cases of dyshormonogenetic goiter was carried out correlating patterns of hyperplasia and the atypias of the glandular tissues with specific defects in hormonal synthesis, including (1) thyroglobulin synthesis defect (Group I, n = 8); (2) defective organification of iodide (Group II, n = 11); and (3) iodide transport defect Cited by: The Influence of Temperature on the Rat Thyroid Ultrastructure, “Sistema termoregulyatsii pri adaptatsii organizma k faktoram sredy” (All-Union Conf.

Our hospital provides assistance to populations in Huesca Pyrenees, endemic area of thyroid pathology for iodine deficiency, so that the management of thyroid nodule is a common problem in daily practice. Page 3 of With endemic goiter, the following morphological variants of goiter are encountered.
Diffuse parenchymal goiter occurs in children. The enlargement of the gland is expressed in varying degrees, but more often its mass is times greater than the mass of the thyroid tissue of a healthy child of the corresponding age.
Dyshormonogenetic goiter is a benign thyroid hyperplasia due to hereditary defects in thyroid hormone synthesis. It lacks malignant features common for papillary (Orphan Annie nuclei, psammoma bodies), follicular (capsular invasion) or high grade (necrosis) thyroid cancer. Multinodular goiter (MNG) is the most common of all the disorders of the thyroid gland.
MNG is the result of the genetic heterogeneity of follicular cells and apparent acquisition of new cellular qualities that become inheritable.
Nodular goiter is most often detected simply as a mass in the neck, but sometimes an enlarging gland produces pressure symptoms. The study of disease; literally, the study (logos) of suffering (pathos). The study of the functional, biochemical and morphological alterations in cells, tissues and organs that underlie disease.
General Pathology: The study of the basic reactions of cells and tissues File Size: 42KB. Two types of goitre occur in endemic areas; (1) a true " hypertrophic " goitre in which the secretory phase of the thyroid is in evidence and which represents a critically balanced compensation, and (2) a colloid " heterotrophic " goitre representing an " imbalance" of thyroid function.
The effect of iodine is to exaggerate the secretory activity of the thyroid when this is a critical necessity Author: G. Williamson, I. Pearse. Iodine, a micronutrient that plays a pivotal role in thyroid hormone synthesis, is essential for proper health at all life stages.
Indeed, an insufficient iodine intake may determine a thyroid dysfunction also with goiter, or it may be associated to clinical features such as stunted growth and mental retardation, referred as iodine deficiency disorders (IDDs). Iodine deficiency still remains Author: Cinzia Giordano, Ines Barone, Stefania Marsico, Rosalinda Bruno, Daniela Bonofiglio, Stefania Catala.

Features of inflammation if the enlargement is infective or autoimmune in nature such as pain in the neck. Hemorrhage and/or necrosis may be a result of traumatic injury to the organ.
Non-specific symptoms of goiter. Most goiters are asymptomatic. A visible thyroid enlargement can only be seen from a volume of about 40 : Palpable goiter, not visible when bending the head back, solitary nodule. Marine, D. () Certain features of the morphologic pathology of endemic goiter.

ISBN Compared with endemic goiter, low socioeconomic status appeared to be the major factor accountable for the high prevalence of advanced stage cases and anaplastic carcinomas.
Iodine deficiency appeared to play a specific role in the increased prevalence of follicular types of. Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as cretinism due to untreated congenital hypothyroidism, which results in developmental delays and other health deficiency is an important global health issue, especially for fertile and pregnant lty: Endocrinology.
A neck mass is an abnormal change in the volume and/or structure of organs or tissues of the neck. Neck masses usually arise due to a thyroid pathology (nodular goiter, tumors, etc.).
