Introduction: Ectopic and atypically localized parathyroid adenomas such as in the anterior mediastinum, paraesophageal or retrotracheal position, although rare, can be seen in clinical practice. Ultrasound (US) which is a frequently used and one of the best conventional imaging modality sometimes fails to identify the lesion especially in atypically localized adenomas. Endoscopic US (EUS) is a new technique that can be used for localization of parathyroid lesions. We reported...

Introduction: Parathyroid lipoadenoma (PLA) is a rarely seen, benign variant of parathyroid adenoma (PA). However, PA usually consists of uniform, polygonal chief cells with a few nests of oxyphil cells, PLA consists of similar histologic features, but with an abundance of fat cells. Additionally, PLA may be functional with the secretion of parathyroid hormone (PTH) or non-functional. Here, we present a case of atypical PLA presented with severe hypercalcemia and skeletal defo...

Introduction: Neoplasms of the thyroid gland are classified according to the cell that it originates and commonly they originate from follicular or parafollicular C cells. The most common differentiated thyroid cancers (DTC) are papillary and follicular carcinomas. Coexistence of two different histological types of primary follicular thyroid neoplasm is a rare condition. There are previous reports of concomitant medullary and papillary thyroid cancers. However, there is scarce...

Introduction: It is unclear whether ultrasonographic (US) findings and fine-needle aspiration biopsy (FNAB) results of nodules accompanied with Hashimoto’s thyroiditis (HT) are affected by the presence of thyroiditis or not. In this study, we compared US features and cytological results of nodules in patients with and without HT.Methods: Patients who underwent FNAB in our clinic were evaluated prospectively. Nodules in patients with and without HT w...

Introduction: Fine-needle aspiration (FNA) is a simple, the most cost-effective, less invasive and a commonly used diagnostic tool for evaluating thyroid nodules. Recent times a tech-nique called fine-needle sampling non-aspiration (FNNA) or fine-needle capillary thyroid biopsies (FNC) has been more preferred. This technique prevents the use of suction so there is no aspiration crush and there-fore nondiagnostic outcomes are reduced. The aim of this prospective study was to co...

Aim: Radioactive iodine (RAI) is one of the treatment approaches in Graves and toxic nodular or multinodular goiter (TNG/TMNG) with low cost and high efficacy. In this study, we aimed to evaluate ultrasonographical and cytological features of thyroid nodules in patients who were treated with radioactive iodine for hyperthyroidism years ago.Methods: Patients who had a history of RAI treatment for hyperthyroidism and had thyroid nodules that were evaluated...

Introduction: Reoperative surgery for thyroid disease is rare. It is sometimes indicated for nodular recurrence after partial surgery for initially benign thyroid disease or for a completion total thyroidectomy when a final diagnosis of thyroid cancer is confirmed on a permanent section of a partially removed thyroid gland. We aimed to investigate the demographic features and reoperation indications in patients with reoperative thyroidectomy.Methods: Thi...

When follicular thyroid carcinoma (FTC) is diagnosed, 25% of the patients extrathyroidal invasion, 5–10% lymphatic metastasis and 10–20% distant metastasis are determined. The most common site of distant metastases of FTC is the lung, followed by the bone. The incidence of skull metastasis of FTC is about 2.5–5.8%. Skull metastasis of FTC was located in the skull base and occipital area.Case: A 60-year-old man admitted at 2006. He was oper...

Aim: The aim of this study is to correlate the histopathological cell types and morphologic features of parathyroid neoplasms with ultrasound(US) images and laboratory findings, and also gain more information about the clinical importance of these results.Materials and methods: The parathyroid lesions of 57 patients who were operated for hyperparathyroidism were sampled on saggital plane. The slides were scanned on high resolution and digital whole slide...

Introduction: High values of fine needle aspiration washout thyroglobulin (FNA-Tg) are diagnostic for metastatic lesions of thyroid cancer. However, there is not a consensus on cut-off for high Tg level. The most important confounding factor for FNA-Tg is inability to calculate Tg per unit volume because residual aspiration material in the needle cannot be known exactly. Another problem is possible contamination of whole blood during lymph node aspiration. In this study, we ai...
