Laboratory procedures available for aid in the differential diagnosis of thyroid tumors include serum hormone measurements, a variety of thyroid scanning procedures, ultrasonography and needle biopsy of the thyroid. Serum calcitonin measurements appear to be highly reliable indicators of the pres­ ence of medullary carcinoma of the thyroid gland. Thyroid scans using isotopes of iodide or techne...

Incidence of primary hyperparathyroidism due to parathyroid carcinoma along with non-medullary thyroid carcinoma is extremely rare. The authors present the unique case of a patient with a 4.3 × 3.1 × 2.5 cm parathyroid carcinoma on the left side, and a 5 mm papillary thyroid microcarcinoma on the right side. The patient was operated thrice because of persistent hyperparathyroidism. The literatu...

INTRODUCTION Medullary thyroid cancer is a rare carcinoma. Surgery is the only curative treatment and since cervical lymphnodes metastases are frequent and can occur at an early stage, a standardized central lymphnode dissection is associated to total thyroidectomy. However, the extent of lymphadenectomy to the lateral neck lynphnodes remains debated. To reduce the extent of lymphnode excision,...

Immunohistochemical studies were conducted in 20 cases of canine thyroid tumours. On histological grounds the tumours included four well-differentiated follicular and four well-differentiated medullary carcinomas. Four tumours were suspected to be of possible follicular origin but were poorly-differentiated or anaplastic (undifferentiated); similarly six tumours that were poorly-differentiated ...

INTRODUCTION: Medullary carcinoma is a rare malignant neuroendocrine tumor of the thyroid gland. (MTC) has no specific clinical symptoms. Due to absence symptoms, disease usually diagnosed at stage metastatic lesions regional lymph nodes, and sometimes, internal organs. The five- ten-year survival after detection distant metastases 25% 10%, respectively. OBJECTIVE: To analyze available foreign ...

OBJECTIVE Due several overlapping histomorphological features and pitfalls in thyroid pathology, there is need to establish a panel of immunomarkers that would aid in proper diagnosis. This study was carried out to investigate the ability of HBME-1, CK19, and S100 in differentiating between hyperplastic, benign and malignant thyroid lesions. MATERIALS AND METHODS Immunohistochemical analysis ...

In the past 5 years, endoscopic neck surgery has been performed by various surgeons in Japan. However, many problems remain to be solved, including indications for this related in malignant thyroid tumors. For small thyroid cancers and legions suspected of malignancy, we found that we could obtain radicality in endoscopic neck surgery that was comparable to that attainable by conventional metho...

We are reporting a case of a 42-yr-old female with a history of right breast carcinoma. She was surgically treated (breast quadrantectomy with axillary dissection) and receiving a third cycle of adjuvant chemotherapy when a feeling of a constant pressure in the front of the neck and lack of air occurred. Subsequent work-up revealed a node in the right thyroid lobe with enlarged paratracheal bil...

Note Medullary thyroid cancers (MTC) are rare tumors of neuroendocrine origin that arise from parafollicular C cells which secrete a variety of peptides and hormones including calcitonin. As opposed to the more common papillary and follicular thyroid cancer subtypes, MTC represents a rare and under-characterized form of cancer, and can cause death if untreated (Taccaliti et al., 2011). MTC can ...
