Dyshormonogenetic goiterof the thyroid gland Lester D.R. Thompson, MD A Dyshormonogenetic goiter is the name given to a fam ily ofinborn errors ofmetabolism that lead to defects in the synthesis ofthyroid hormone. The prevalence ofthis disease is I in 30,000 to 50,000 live births, and it is the second most common cause (10 to 15%) ofpermanen The clinical presentation of dyshormonogenetic goiter depends upon the severity of the inborn error in thyroid hormone synthesis. A severe defect manifests as neonatal or congenital hypothyroidism, growth abnormalities, and mental retardation (cretinism). Milder defects may present later in life as goiter and mild hypothyroidism Goiter refers to any visible enlargement of the thyroid gland The lumens are small or nearly-occluded and contain little or no colloid. Cytologic atypia is less pronounced than the previous case. The treatment of dyshormonogenetic goiter generally consists of thyroid hormone replacement. Surgery is indicated if goiter is causing compression symptoms Familial Dyshormonogenetic Goiter Familial dyshormonogenetic goiter has been reported in sheep, cattle, goats, and pigs and appears to be inherited as an autosomal recessive trait. Essentially, it is a genetic enzyme defect in the biosynthesis of thyroid hormones
Thyroid dyshormonogenesis is a rare condition due to genetic defects in the synthesis of thyroid hormones. Patients develop hypothyroidism with a goiter. It is due to either deficiency of thyroid enzymes, inability to concentrate, or ineffective binding Dyshormonogenetic goiter: Increased cellularity is usually diffuse Follicular carcinoma: Has vascular or capsular invasion, although multinodular goiter may have vascular invasion at periphery of nodule Papillary carcinoma: Distinct nuclear features seen in papillary carcinoma; lacks the Sanderson polsters found in goiters Toxic goiter An iodide transport defect (ITD) in the thyroid gland was determined to cause congenital dyshormonogenic hypothyroidism with goiter (CDHG) in 2 members of a family of Shih-Tzu dogs. Strikingly, both dogs were also diagnosed with dilated cardiomyopathy at 24 and 1.5 mo of age. The only sign of hypoth

The fibrous bands encapsulate individual nodules and extend within the nodules to surround individual abnormal follicles (as shown here). Irregular bands of fibrosis at the edge of nodules can mimic capsular invasion Dyshormonogenetic goiters (DG) are genetically determined thyroid hyperplasias due to enzyme defects in thyroid-hormone synthesis. Hypothyroidism is documented in 64% of cases. The thyroid gland is enlarged and multinodular in all cases, weighing up to 600g
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. Fetal goiter is a rare disorder not expected to be found during a healthy woman's pregnancy. It can be a prenatal manifestation of congenital hypothyroidism due to thyroid dyshormonogenesis and it can lead to serious perinatal complications. A vascularized fetal neck mass was detected at 29 weeks' gestation of a healthy primigravida Dyshormonogenetic goiter (DG) is a rare disorder that affects 1 in 30,000 to 50,000 live births. Males are affected as commonly as females and most patients are discovered before age 20 (1). Patients typically present at birth or shortly thereafter with hypothyroidism, goiter or growth retardation (cretinism)
Neonatal dyshormonogenetic goiter with hypothyroidism may represent an unusual cause of neonatal neck mass. Early identification and hormone replacement therapy are crucial for a better neurodevelopmental outcome. Genetic analysis is mandatory in order to reach a specific diagnosis and to elucidate new patterns of thyroid disorder Comments: Cytologic atypia can be quite striking in dyshormonogenetic goiter. In almost 20% of cases, it is so severe as to lead to a mistaken diagnosis of follicular, papillary, medullary, or undifferentiated carcinoma (Ghossein RA, Rosai J, Heffess C.

He had short stature (-2.3 SD), diffuse goiter and a particularly large nodule in the right lobe of the thyroid gland Fetal dyshormonogenetic goiter is a rare disease characterized by increased fetal thyroid gland size due to inherited defects in genes that control thyroid hormone synthesis and transportation. The incidence varies between 1:30,000 and 1:50,000 live births in the European and North American regions, and it accounts for up to 15% of congenital.
Dyshormonogenetic goiter is a rare entity that presents in patients who typically have a history of congenital hypothyroidism, and generally arises from a genetic mutation compromising the production of functional thyroxine or thyroglobulin. Clinically, physical manifestations of goiter can result if left untreated. Histologically, the thyroid lesions usually show prominent bridging fibrosis. DOI: 10.1007/BF02739962 Corpus ID: 9038193.

DOAJ is a community-curated online directory that indexes and provides access to high quality, open access, peer-reviewed journals Conclusion. Dyshormonogenetic goiter is a rare entity, representing one of the causes of congenital hypothyroidism. It is morphologically characterized by architectural and cellular pleomorphism that may mimic thyroid malignancy and cause difficulties in differential diagnosis Goiter is a condition in which the thyroid gland is swollen. Because the thyroid is located in the front of the neck, once it enlarges, it causes a visible protrusion in the neck. This swelling is normally painless; however, if it becomes too large, it can lead to sore throat, coughing or even breathing difficulties
Discussion. Congenital hypothyroidism presenting with thyroid enlargement is very rare (1 per 40,000) and can be found in only 10% to 15% of all cases of congenital hypothyroidism. 1 Dyshormonogenesis occurs with a frequency of 1 per 30,000 neonates, accounting for approximately 15% of all hypothyroid neonates. This disorder is caused by an autosomal recessive mutation in the genes encoding. Dyshormonogenetic goiter is rare, with a prevalence estimated to be 1 in 30,000 to 50,000 population. It is the second most frequent cause of permanent congenital hypothyroidism. However, only patients with the most severe impairment in thyroid hormone production present clinically in infancy with cretinism This is the first report showing the neuropsychological evaluation in patients with dyshormonogenetic fetal goiter. More studies are needed to understand the neurodevelopmental outcomes of neonates with CH-induced fetal goiters. Introduction. Congenital hypothyroidism (CH) is the most prevalent. 5.2.3 Goiter. Goiter is a nonspecific term meaning enlargement of the thyroid and encompasses multinodular, endemic, dyshormonogenetic, diffuse toxic, and amyloid goiter. These entities, with the exception of amyloid goiter, are associated with hyperplastic changes of the follicles

Studies are presented on the 131 I-T 4 half-life values in 3 untreated and 2 treated patients with dyshormonogenetic goiter, 7 thyrotoxic, 8 euthyroid and 8 hypothyroid patients. The untreated patients with dyshormonogenetic goiter had results out of keeping with their clinical status. Possible reasons for these findings are discussed A dyshormonogenetic goiter is a congenital hyperplasia of the thyroid parenchyma caused by a defect in the noraml hormongenetic pathway. Here, we report on a case involving the simultaneous occurrence of a thyroid and an ectopic thyroid dyshormonogenetic goiter Medeiros-Neto et al. (1997) reported diagnosis of fetal dyshormonogenetic goiter with hypothyroidism, probably due to defective thyroglobulin synthesis, by ultrasound and cordocentesis at 28 weeks of gestation. They found that after a single injection of levothyroxine the fetal goiter decreased in size, and at birth the neonate had normal. The dyshormonogenetic goiter was related to an organification defect due to a mutation in the thyroid peroxidase (TPO) gene. Subjects and Methods Patient.

Background: Dyshormonogenetic goiter and Hashimoto's thyroiditis are amongst the commonest causes of hypothyroidism in children and adolescents Worldwide. But, the genetic basis and their hypothyroid phenotypes are under-reported, especially from developing countries There was no difference in c-myc, p53, and TGF-β mRNAs expression between dyshormonogenetic and normal tissues. The overexpression of EGF and EGF-R mRNAs found in dyshormonogenetic tissues may suggest that this growth factor may play a role in cellular proliferation and contribute to goiter formation Papillary Thyroid Carcinoma with Lung Metastasis Arising from Dyshormonogenetic Goiter: A Case Repor o Causes: Hereditary enzymatic defects - Interfere with thyroid hormone synthesis, transmitted as autosomal-recessive conditions (e.g. dyshormonogenetic goiter), Ingestion of substances that interfere with thyroid hormone synthesis & unknown cause - in most cases of sporadic goiter the cause is not know However, thyroid gland size and radionuclide uptake failed to completely normalize in all of our goitrous cats despite long-term, adequate thyroid hormone replacement, similar to findings reported in younger cats with congenital hypothyroidism, 74 as well as humans with dyshormonogenetic goiter. 4
