Backround. Thyroglossal duct cyst (TDC) is a developmental abnormality of the thyroid gland. Due to embryological remnants of thyroid tissue located in the TDC, the same malignant tumors that develop in the thyroid gland can also develop in the TDC. Methods. We present the unique case of a 39-year-old female with simultaneous de novo papillary carcinoma in a TDC and the thyroid gland. Results. ...

Abstract. A case of a female, 10-year-old rhesus macaque (Macaca mulatta) with spontaneous chronic lymphocytic thyroiditis is presented. At necropsy, the thyroid gland was slightly enlarged, up to 2 mm large, round, confluent, beige foci on surface both lobes. Histopathologic features resembled human Hashimoto's thyroiditis: multifocally, interstitium infiltrated by lymphocytes and variably siz...

Introduction: Primary squamous cell carcinoma (SCC) of the thyroid gland is one of the rarest types of all reported thyroid malignancies worldwide. It is very aggressive in nature and carries a poor prognosis. The surgical resection with adjuvant radiotherapy and chemotherapy is the most recommended treatment despite its poor reported outcome.  Case Report: A 74-year-old woman presented wit...

OBJECTIVES There is limited endosonographic literature regarding thyroid gland pathology, which is frequently visualized during upper endoscopic ultrasound (EUS). Our objective was to assess the prevalence of benign and malignant thyroid lesions encountered during routine upper EUS within a cancer center setting. MATERIALS AND METHODS The data were prospectively collected and retrospectively ...

The thyroid gland, a highly vascular endocrine gland, is composed of two lateral lobes connected by a narrow median isthmus thus giving an 'H' shaped appearance to the gland. A wide range of morphological variations and developmental anomalies of the thyroid gland have been reported in the literature. In our study, on the morphometric features of the thyroid gland it was found that, 6 out of 41...

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 radia...

AIM OF THE STUDY Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thy...

OBJECTIVE To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. MATERIALS AND METHODS Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with c...

The development of benign and malignant neoplasms was studied in thyroid glands of Long-Evans rats 2 years after either both lobes of the glands had been irradiated with 500, 1000, or 2000 r, or the right lobe alone had been irradiated with 1000 r. The degree of follicular atrophy and of nuclear pleomorphism observed in these ir radiated glands varied with the dose of x-rays. Benign nodules or ...
