Renal cell carcinoma (RCC) has a high metastatic potential, and most commonly metastasizes via the bloodstream, although lymphatic metastases also occur. RCC is well-known for its propensity to metastasize to unusual sites, and late metastasis, even after a number of years, is common. The occurrence of RCC metastasis to the head and neck region is uncommon, and occurs primarily in the thyroid gland and in patients with widespread dissemination. Involvement of the parathyroid gland in metastatic carcinoma is extremely rare...

BACKGROUND: The relation between Hashimoto's thyroiditis (HT) and papillary thyroid carcinoma (PTC) remains controversial. We aimed to study the coexistence of PCT and HT and the diagnostic utility of cytokeratin19 and P63 proteins expression in all positive for PTC cases of HT. SUBJECTS AND METHODS: We analyzed data from 343 patients who underwent fine needle aspiration cytology followed by thyroid surgery over a six years period. Thyroid scans and blood measurements for anti-thyroid peroxidase antibodies (TPOAb), thyroid stimulating hormone (TSH), anti-thyroglobulin antibodies (TgAb) and free thyroid hormones were performed...

Different imaging tools, circulating endocrine markers, and fine-needle aspiration (FNA) cytology are of great importance in the diagnosis and follow-up of different thyroid and parathyroid diseases. Sometimes, however, they are conflicting or inconclusive: interestingly, measuring endocrine markers (i.e. thyroglobulin, calcitonin, parathyroid hormone) in fluids from FNA proved to be a very useful complementary diagnostic tool in such cases. The determination of endocrine markers in fluids other than serum/plasma has been developed in the last years...

Thyroid cancer is the most common endocrine malignancy. Differentiated thyroid cancer (DTC) with the two subtypes, papillary thyroid cancer (PTC) and follicular thyroid cancer (FTC), is the most frequent subtype of thyroid cancer; more rare subtypes are medullary thyroid cancer (MTC) and anaplastic thyroid cancer (ATC). The incidence of DTC has increased rapidly in recent years due to the more frequent use of imaging methods such as ultrasound of the neck and fine-needle aspiration (FNA) of thyroid nodules...

BACKGROUND: Papillary thyroid carcinoma (PTC) is frequently associated with cervical lymph node metastases. Guidelines recommend performing ultrasound-guided fine-needle aspiration cytology (FNAC) for suspicious nodes to guide management. No specific recommendations are available for the use of FNA thyroglobulin assay (FNA-Tg). This study investigated the diagnostic value of performing FNAC and FNA-Tg. METHODS: Patient demographics, preoperative investigations, surgery, and lymph node pathology were collected for patients with PTC who underwent lateral neck lymphadenectomy and central compartment reexploration from January 2000 to July 2015...

Fine-needle aspiration (FNA) is commonly used as a preoperative assessment to diagnose thyroid cancer. However, misdiagnosis of malignancy by FNA is not rare, even if image examination suggests the possibility of thyroid cancer. In the present study, the clinicopathological factors of patients whose preoperative FNA examination had not led to a diagnosis of thyroid cancer were examined. In total, 125 patients with thyroid cancer who underwent FNA and surgery (total thyroidectomy, subtotal thyroidectomy or hemithyroidectomy) at the Department of Surgery, Surgical Oncology and Science of the Sapporo Medical University Hospital between 2006 and 2013 were retrospectively analyzed...

BACKGROUND: Lymph node (LN) recurrence detected by ultrasound (US) is a very common problem after initial treatment for papillary thyroid carcinoma (PTC). Most patients with PTC have an excellent disease-specific survival even with LN recurrence. Recently, watchful waiting with serial cervical US evaluations would be considered a reasonable approach to management of LN recurrence in selected patients. On the other hand, some patients with LN recurrence have demonstrated clinically significant disease progression during follow-up...

BACKGROUND: Fine-needle aspiration cytology (FNAC) is useful for evaluating cervical lymph nodes for metastases from thyroid carcinomas. Reports have illustrated that with application of standardized technique and appropriate cutoffs, thyroglobulin (TG) washout studies increase the sensitivity and specificity of FNAC in identifying lymph node metastases. This project describes our experience at an academic medical center utilizing needle wash thyroglobulin analyses as an ancillary to FNAC...

BACKGROUND: Preoperative diagnosis of lymph node metastasis from thyroid carcinoma is usually confirmed by using fine needle aspiration cytology (FNAC) when thyroid carcinoma is suspected based on the clinical findings. However, the result of FNAC sometimes leads to a false negative, especially in cases of hypocellular lesions such as metastases with cystic change. Thyroglobulin measurement in fine needle aspirates (FNA-Tg) has been shown to be a useful technique to detect the protein specifically secreted by thyroid follicular cells...

OBJECTIVE: To evaluate the diagnostic accuracy of a modified scrape cell block (SCB) technique in a large series of patients. The technique was especially developed and tested for fine-needle aspiration of thyroid and parathyroid nodules. STUDY DESIGN: Eighty-two ultrasound-guided fine-needle aspiration specimens with the sonographic aspect of a thyroid (n = 33) or a possible parathyroid nodule (n = 49) were studied. Immunohistochemistry (IHC) was used on cell blocks containing plasma, thromboplastin, and selected 3-dimensional cell aggregates scraped off Papanicolaou-stained smears...

Oxyphilic (oncocytic) parathyroid lesions are very uncommon and their cytological features are rarely described. Due to the similarities in anatomical location and indistinguishable cytomorphological features, these lesions are easily confused with neoplastic and non-neoplastic thyroid lesions on fine needle aspiration (FNA). The diagnosis becomes more challenging in cases of unusual intrathyroidal location of the parathyroid lesions in the absence of clinical evidence of hyperparathyroidism, which simulate thyroid nodules clinically...

BACKGROUND: Assessment of cervical lymph node involvement in patients with thyroid cancer either during preoperative surgical mapping or detection of recurrences during follow-up is a crucial step in the management of differentiated thyroid cancers (DTCs). In most patients, fine needle aspiration cytology (FNAC) confirms the presence of metastasis in lymph node. However, in cases of paucicellular lymph node aspirate or discordant sonogram and cytology results, thyroglobulin (Tg) measurement in the lymph node aspirate (FNA-Tg) is useful and a value >1 ng/ml is considered consistent with metastatic disease...

BACKGROUND: Patients with papillary thyroid cancer (PTC) and enlarged cervical lymph nodes (CLNs) are usually assessed by fine-needle aspiration biopsy cytology (FNAB-C). Thyroglobulin (Tg) is frequently detected in washout of fine-needle aspirates (FNA) of these lymph nodes. The aim of this study was to evaluate the accuracy of the measurement of FNAB-Tg in the washout of FNAB in combination with FNAB-C to detect CLN metastases in PTC. METHODS: We retrospectively evaluated 163 surgically proven CLNs...

UNLABELLED: Resistance to thyroid hormone (RTH) is a syndrome of reduced tissue responsiveness to thyroid hormones. RTH is majorly caused by mutations in the thyroid hormone receptor beta (THRB) gene. Recent studies indicated a close association of THRB mutations with human cancers, but the role of THRB mutation in carcinogenesis is still unclear. Here, we report a rare case of RTH with a papillary thyroid carcinoma (PTC). A 26-year-old woman was referred to our hospital due to a thyroid tumor and hormonal abnormality...

Thyroid nodules are detected in up to 50 to 60% of healthy subjects. Most nodules do not cause clinically significant symptoms, and as a result, the main challenge in their management is to rule out malignancy, with ultrasonography (US) and fine-needle aspiration (FNA) biopsy serving as diagnostic cornerstones. The key issues discussed in these guidelines are as follows: (1) US-based categorization of the malignancy risk and indications for US-guided FNA (henceforth, FNA), (2) cytologic classification of FNA samples, (3) the roles of immunocytochemistry and molecular testing applied to thyroid FNA, (4) therapeutic options, and (5) follow-up strategy...
