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...

Idiopathic granulomatous hypophysitis is a very rare inflammatory disease of the pituitary gland. Primary hypophysitis represents a difficult diagnostic challenge because it can imitate pituitary adenomas clinically and radiologically. The diagnosis is usually made histologically by hypophysectomy. We herein present a rare case of idiopathic granulomatous hypopysitis diagnosed primarily by pituitary biopsy.Case: A 50-year-old female patient presented wit...

Cardiovascular deleterious effects of short term hypothyroidism are not well known. We aimed to investigate proprotein convertase subtilisin/kexin type 9 (PCSK9), soluble lectin-like oxidized LDL receptor 1 (sLOX-1) and ankle brachial index (ABI) in patients with thyroid cancer with short term overt hypothyroidism due to thyroid hormone withdrawal (THW). Twenty-one patients who require radioactive iodine (RAI) ablation or RAI scan and thirty-six age, sex, BMI similar euthyroid...

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...

Objective: Serum total sialic acid(SA) concentration is assessed as an up to date risk indicator of atherosclerosis and cardiovascular diseases.Methods: It was aimed to investigate about how SA levels are effected in overt or subclinical hypothyroidism (SH) and how it’s associated with other atherosclerosis risk factors because there is no study about these topics, though SA is intensively studied in recent years.Patients: Six...

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...

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 ...
