Intrathyroidal parathyroid carcinoma is extremely rare clinical entity with potentially multiple diagnostic pitfalls. We report a case of 40-year-old man presented with classical manifestations of primary hyperparathyroidism, severe hypercalcemia and profoundly increased serum parathyroid hormone level. Neck ultrasonography demonstrated multinodular goiter with predominant 34 mm nodule in left ...

An 80-year-old female presented with an incidental finding of a retrosternal mass on magnetic resonance imaging. Ultrasound demonstrated a mediastinal lesion adjacent to but separate from the inferior pole of the right thyroid lobe. Fine needle aspiration cytology demonstrated colloid and follicular cells. At surgery, the right thyroid lobe was found to be normal. A discrete 5 cm nodule was fou...

The thyroid gland is a known site for metastatic tumors from various primary sites. Thyroid metastases are not an exceptional finding at autopsy, and they are encountered in 2% to 9% of the patients with malignant neoplasm. The most frequent tumors to metastasize are breast, lung, melanoma, and kidney carcinomas. Despite the fact that it is one of the largest vascular organs in the body, clinic...

PURPOSE Papillary thyroid carcinoma (PTC) arising from the pyramidal lobe is rare; therefore, clinicopathologic evaluation is lacking. In addition, the rate of occult malignancy in the pyramidal lobe after thyroid surgery is unclear. This study is to evaluate the clinical characteristics of PTCs that involve the pyramidal lobe. METHODS The study enrolled 1,107 patients who underwent thyroid s...

INTRODUCTION It is not uncommon for patients with indeterminate thyroid nodules to undergo diagnostic hemithyroidectomy. When the final pathology determines that the nodule is in fact malignant, patients require counseling as to the whether a completion thyroidectomy is necessary. OBJECTIVES 1. Determine the incidence of well differentiated thyroid cancer (WDTC) in the contralateral thyroid l...

In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...

A 55-year-old female underwent total thyroidectomy for medullary carcinoma of the left lobe of the thyroid. The right lobe showed an incidental occult papillary carcinoma. There was also diffuse lymphocytic thyroiditis. Immunohistochemistry for calcitonin and thyroglobin confirmed the separate histogenesis for both carcinomas. The coexistence of medullarry and papillary carcinoma of the thyroid...

A 42-year-old female Jordanian patient presented with a history of sudden painful dysphagia following swallowing of a fish bone. Though soft tissue X-rays showed a foreign body in the neck, repeated oesophagoscopies failed to reveal it. Computed axial tomography was done and showed a fish bone embedded in the left thyroid lobe. Left thyroid lobectomy was carried out and the fish bone was seen w...

Thyroidal 99mTc uptake in the acute thyrotoxic phase of subacute thyroiditis (SAT) is always inhibited. However, a patient with SAT had signs in the right-side thyroid gland with transient thyrotoxicosis and slightly high 99mTc uptake levels in the right lobe, low 99mTc uptake in the left lobe, and normal overall uptake. Histological examination showed cellular destruction and granulomatous inf...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...
