Introduction: Ocular changes are common in various endocrine disorders. However, there are only few studies reporting ocular changes in patients with primary hyperparathyroidism (PHPT). Here, we examined central corneal thickness (CCT) and retinal thickness (RT), intraocular pressure (IOP) and their relationships with serum intact parathyroid hormone (iPTH), calcium (Ca), and phosphorus levels in PHPT patients.Methods: Thirty-seven patients with PHPT wer...

Introduction: Primary hyperparathyroidism (pHPT) is a common endocrine disease mainly caused by single or multiple hyperfunctioning parathyroid lesions. In 2–7% of cases, surgery is not curative at first operation and reoperation is required. Ultrasonography and sestamibi scan are the most widely used methods for identification of the culprit parathyroid gland with the disadvantage of high false positives caused by other cervical pathologies. Herein we aimed to search the...

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...

Introduction: Radioactive iodine (RAI) therapy is widely used in the treatment of hyperthyroidism especially in patients with Graves’ disease (GD), toxic multinodular goitre (TMNG), and toxic adenoma. RAI may lead to worsening of the autoimmunity with the elevation of TSH-receptor antibody (TRAB). In this study, we aimed to compare the effects of surgery or RAI treatment on TRAB.Methods: Hyperthyroid patients were divided into three groups; patients...

Introduction: We report stage IV B cell lymphoma in a patient presenting with adrenal failure and an intraabdominal mass which imaging techniques were suggestive for paraganglioma.Case report: A 71-years-old woman admitted to our emergency clinic with severe fatigue and stupor. She was diagnosed to have primary adrenal failure since serum ACTH was 229 pg/ml and cortisol response to 250 μg co-syntropin was 6.17 μg/dl. In abdominal MRI, bilateral...

Primary hyperparathyroidism (PHPT) is usually caused by single adenoma. Functional parathyroid cysts are a rare cause of PHPT. Parathyroid cysts can be subdivided into nonfunctional, without biochemical derangement, or functional, with elevated serum calcium accompanying clinical evidence of hyperparathyroidism. Parathyroid cysts are found in the neck and anterior mediastinum. Functional parathyroid cysts are not only secretary but larger cysts can lead to compression symptoms...

Introduction: Patients with parathyroid carcinoma (PCA) and synchronous disease in other parathyroid glands have been reported in the literature. Here, we report a patient who had persistant hypercalcemia after operated from parathyroid carcinoma and improvement of hypercalcemia after the subsequent operation from atypically localised parathyroid adenoma.Case report: A 62-year-old man presented with a history of headache, fatigue, and nervousness. Labora...

Background: Adrenocortical carcinoma (ACC) is a very rare but typically aggressive malignancy. About one to three quarters of ACC is functioning with excess hormonal production.Case: A 44-year-old female patient was admitted to out-patient clinic with obesity, oligomenorrhea and abdominal pain. She had central obesity, buffalo hump, and palpable flank mass. Hypertension, transient ischemic attack, and epilepsy history was present.S...

Introduction: Anaplastic thyroid carcinomas (ATCs) are sometimes accompanied by well-differentiated carcinomas (WDCs), and ATCs have been speculated to be dedifferentiated from the preexisting or coexisting WDCs. We will present two cases determined with both ATC and papillary thyroid carcinoma (PTC.)Case 1: A 82-year-old woman was investigated due to a painful neck mass. Thyroid function tests were normal. Thyroid ultrasonography revealed isohypoechoic ...

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...
