Reported morphologies of the ultimobranchial body had varied between researchers: a cluster of mitotic cells, a duct-like structure and a rosette-like cell mass. To clarify the true morphology, we studied tilted horizontal sections of 20 human embryos (crown-rump length 5-18 mm; 4-6 weeks). The sections displayed a ladder-like arrangement of the second to fourth endodermal pouches and, in 5 early embryos we found the fifth pouch attached to the fifth ectodermal groove near the fourth pharyngeal arch artery...

Based on microscopic and immunohistochemical characterization, we documented spontaneous proliferative and neoplastic lesions in the thyroid and parathyroid glands of nondomestic felids. Ten animals (4 leopards, 3 tigers, and 3 cougars), all with a previous diagnosis of thyroid neoplasia were identified from the University of Tennessee College of Veterinary Medicine database. The mean age of affected animals was 15.9 y. Twelve neoplasms were identified; 2 animals had 2 concurrent neoplasms. After immunohistochemical characterization using a panel of chromogranin A, thyroglobulin, and calcitonin, 7 of the former thyroid neoplasms were diagnosed as thyroid adenomas, 1 was diagnosed as a thyroid carcinoma, and 4 were diagnosed as parathyroid adenomas...

Approximately 300 cases of sporadic parathyroid cyst (PCs) have been reported to date. Only two cases have been described in MEN1 so far. Detection by imaging could be challenging, especially in multiglandular primary hyperparathyroidism (HPT) and clinical outcome could be different. During the period 1990-2014, 71 MEN1 patients were operated for primary hyperparathyroidism in our centre. We report three cases of PCs in MEN1 patients affected by HPT, who underwent a total or subtotal parathyroidectomy with transcervical thymectomy...

Parathyroid cysts (PCs) account for less than 1% of all parathyroid lesions and are most commonly located along thyroid lobes, rarely at ectopic sites. PCs are important because they can pose a differential diagnostic challenge against other cystic formations of the neck. PCs can be functional (elevated serum parathyroid hormone level) and nonfunctional. Four cases of nonfunctional PCs are presented. All four female patients underwent physical examination and ultrasonography of the neck with ultrasound-guided fine-needle aspiration biopsy (UG-FNA)...

This study aims to determine fibroblast growth factor-23 and soluble α-Klotho levels in patients with autosomal dominant polycystic kidney disease. A total of 76 patients with autosomal dominant polycystic kidney disease and 32 healthy volunteers were included in the study. Serum fibroblast growth factor-23 and soluble α-Klotho levels were measured with ELISA kits. Parathyroid hormone, phosphate, calcium, creatinine, 25-hydroxyvitamin D3 levels, urinary protein to creatinine ratio and estimated glomerular filtration rate were also measured or calculated...

INTRODUCTION: Cancer in the parathyroid gland is rare, but parathyroid cancer is occasionally seen in relation to genetic abnormalities. Due to a limited amount of evidence, the optimal handling of these cases is not clear. Furthermore, the presence of a malignant parathyroid tumor is rarely known at the time of the initial operation; therefore, re-operations are often necessary. The aim of this study was to present the case of a patient with a previously diagnosed jaw tumor and parathyroid carcinoma that presents as a recurrence of hyperparathyroid hypercalcemia...

The incidence and range of spontaneous thyroid and parathyroid glands findings were determined in control Han-Wistar and Sprague-Dawley rats, and CD-1 mice from 104-week carcinogenicity studies carried out between 1998 and 2010 at Charles River Edinburgh. In both strains of rats and in CD-1 mice, non-proliferative lesions of the thyroid or parathyroid glands were generally uncommon apart from some findings in CD-1 mice such as ultimobranchial duct/cyst (5.72%), follicular distension/dilatation (3.84%), and cystic follicles (3...

Thyroid lymphoepithelial complexes (LECos) are rare, being reported in lymphoma, Graves-Basedow disease, Hashimoto thyroiditis, pericarcinomatous thyroid or in the context of branchial cleft-like cysts. Here we report immunohistochemical expression of cytokeratin 5/6, P63 and TTF1 in 6 cases of thyroid LECos. Two cases had carbimazole treatment for hyperthyroidia and Graves disease. Anti-thyroglobulin, -thyroperoxidase or -TSH antibodies were detected in 4 cases. NSAID or poviodone iodine allergy were present in 2 cases...

Thyroid hemiagenesis (TH) is a rare congenital abnormality of the thyroid gland, characterised by the absence of one lobe. The true prevalence of this congenital abnormality is not known because the absence of one thyroid lobe usually does not cause clinical symptoms by itself. Between 1970 and 2010, 329 cases of TH have been reported. It is interesting to note that most cases have an agenesis of the left lobe (80% of cases) followed by the isthmus (44-50% of cases). Although the female to male ratio was 1:1...

OBJECTIVE: To evaluate the effects of thyroid cystectomy for primary hyperparathyroidism on immune function. METHODS: Ninety-two patients with parathyroid cysts complicated with primary hyperparathyroidism were randomly divided into a treatment group and a control group (n=46). The treatment group received endoscopic thyroidectomy through the anterior chest wall via the areolar approach, and the control group was treated with conventional open thyroidectomy. RESULTS: The two groups had similar immune function indices as well as thyroid hormone, serum calcium and phosphorus levels before surgery (P>0...

Giant parathyroid cysts (PCs) are a rare entity and possess a benign clinical course. PCs may be functional or non-functional, depending on the ability of the cyst to secrete parathyroid hormone (PTH). The present study reports a rare case of a giant PC in a 56-year-old male who presented to the Affiliated Tumor Hospital, Zhengzhou University (Zhengzhou, Henan, China) with a 10-month history of exertional dyspnea, associated with mild dysphagia that had persisted for 3 months. The present study reviews the clinical situation, laboratory examination, radiographic findings, treatment and prognosis of the patient, and provides a brief discussion regarding the associated literature...

BACKGROUND: Multiple endocrine neoplasia (MEN) type 1 syndrome is an uncommon inherited disorder characterized by the occurrence of tumors involving two or more endocrine glands. These tumors include pheochromocytoma, adrenal cortical and neuroendocrine tumors including (bronchopulmonary, thymic, gastric), lipomas, angiofibromas, collagenomas, and meningiomas. MEN-4 is very rare and has been characterized by the occurrence of parathyroid and anterior pituitary tumors in association with tumors of the adrenals, kidneys, and reproductive organs...

Branchial pouch-derived anomalies may arise from remnants of the first, second, or third/fourth branchial arches. Branchial pouch-related structures are found within the thyroid gland in the form of solid cell rests, epithelial lined cyst with or without an associated lymphoid component, thymic and/or parathyroid tissue, and less commonly in the form of heterotopic cartilage. We present a rare case of left solid thyroid swelling nearby two cervical nodules in a seven-year-old female with a clinical diagnosis suggestive of malignant thyroid tumor with metastasis to the cervical lymph nodes...

Fibro-osseous lesions in mice are progressive aging changes in which the bone marrow is replaced to various degrees by fibrovascular stroma and bony trabeculae in a wide variety of bones. The frequency and severity varied greatly among 28 different inbred mouse stains, predominantly affecting females, ranging from 0% for 10 strains to 100% for KK/HlJ and NZW/LacJ female mice. Few lesions were observed in male mice and for 23 of the strains, no lesions were observed in males for any of the cohorts. There were no significant correlations between strain-specific severities of fibro-osseous lesions and ovarian (r=0...

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally...

We discuss a case of primary hyperparathyroidism caused by a giant cystic parathyroid adenoma presenting with neck swelling and hypercalcemic crisis. Fine-needle aspiration cytology of presumed thyroid swelling from one of the two sites aspirated yielded clear fluid but was not attributed to parathyroid pathology. Elevated serum calcium and intact parathormone (iPTH) levels suggested preoperative parathyroid pathology. Ultrasound neck and sestamibi scan for parathyroid localization were not conclusive. Due to resistant hypercalcemia, the patient underwent emergency bilateral neck exploration and excision of the identified left superior parathyroid cyst along with total thyroidectomy...

We present a case of an 8-year-old girl with a painless swelling in her neck. An ultrasonogram revealed a cystic nodule with internal echoes, lying posterior to right lobe of thyroid, and MRI confirmed it. Thyroid scintigraphy did not show any uptake in the swelling. Intraoperatively, the lesion was densely adherent to the thyroid gland, hence a hemithyroidectomy was performed. Histopathology showed it to be an ectopic cervical thymic cyst with parathyroid tissue.
