A 53-year-old woman presented with labile and difficult to control hypertension on 3 different anti-hypertensive medications. Abdominal computed tomography and ultrasonography of the thyroid gland showed a 1.8 cm thyroid nodule. Fine needle aspiration biopsy of the thyroid nodule revealed papillary thyroid carcinoma. Serum thyroid stimulating hormone and free thyroxine, calcitonin, carcinoembry...

Medullary thyroid carcinoma accounts for 4% of thyroid carcinoma and originates from parafollicular cells, secreting calcitonin and carcinoembryonic antigen (CEA). Conventional radiographic modalities such as Computerized Tomography (CT), Magnetic Resonance Imaging (MRI), and Ultrasonography (U/S), are used for detecting recurrences following total thyroidectomy. However, metastatic disease fre...

Ectopic thyroid tissue is most commonly located in a single location, this being the lingual area. Presentation with two ectopic thyroid foci is quite unusual. A girl patient aged 7 years who presented with complaints of two masses in the right anterior neck and submandibular area is reported. Her growth pattern and development were normal. The masses were detected to be dual ectopic thyroid gl...

large median endodermal anlage and two lateral anlages (1). Commonly, the median anlage fails to descend, resulting in a lingual thyroid gland. In rare cases, failure of the lateral anlage to fuse with the median anlage produces a lateral ectopic thyroid gland (2). There are a number of case reports of papillary thyroid carcinomas in ectopic thyroid tissue, but there are only a few cases of pri...

Complementary medications and herbal medicine for weight loss have become very popular. We report a case of thyroid dysfunction following the ingestion of a kelp-containing marketed diet in a 45-year-old woman with no previous thyroid disease. Signs of hyperthyroidism occurred shortly after a kelp-containing diet. Hyperthyroidism lasted 2 months and was followed by an overt hypothyroidism. The ...

Mucoepidermoid carcinoma of the trachea is a rare tumor. We report an 80-year-old male with mucoepidermoid carcinoma in the upper trachea with invasion of the isthmus of thyroid gland. The patient’s major symptom was dyspnea with coughing. Computed tomography scan showed a protruding mass into the trachea suspected of thyroid cancer. Ultrasonography also revealed the suspicion of an invasive th...
