Introduction: Klinefelter syndrome is known as the set of symptoms that result from two or more X chromosomes in males. There is no known association of this syndrome with GH hypersecretion. The most remarkable symptom is gigantism and it can also be observed in androgen deficient states as such as the Klinefelter syndrome and some more genetic syndromes such as the Sotos syndrome, the Marfan syndrome, the homocystinuria, and the fragile X-syndrome. Herein we presente...

Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases characterized by enzyme deficiencies in cortisol secretion. The most common form is 21-alpha hydroxylase deficiency. Here, we report a patient with undertreated CAH and bilateral large adrenal masses.Case report: 34 years old male patient diagnosed with CAH and testicular anorchia at the age of 7 admitted to our clinic for general weakness. Hydrocortisone treatm...

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: Primary hyperparathyroidism (pHPT) during pregnancy is rare and associated with increased morbidity for both mother and fetus. Maternal complications of pHPT include nepfhrolithiasis, pancreatitis, cardiac arrhytmias, hypertension, nausea and vomiting. pHPT is caused by a solitary adenoma in 85–90% of patients, and the curative treatment is parathyroidectomy. Here, we presented two women who have diagnosed pHPT and operated without complications in pregnancy...

Introduction: Premature ovarian failure (POF) is a disorder associated with female infertility, and it affects approximately 1% of women under the age of 40 year. It is considered a multifactorial, heterogeneous condition, for which the exact underlying cause remains unclear. Associations with autoimmune diseases, environmental factors and genetic causes have been described. Herein we presented a case with POF who regained fertility after the treatment of Graves disease.<p...

Introduction: Tolosa Hunt syndrome (THS) is described as unilateral orbital pain associated with paresis of one or more of the third, fourth and/or sixth cranial nerves caused by a granulomatous inflammation in the cavernous sinus, superior orbital fissure or orbit. Pituitary gland is rarely involved in this syndrome. Herein we represented a case with hypophysitis with Tolosa Hunt who was operated with the suspicion of pituitary adenoma.Case: A 63-year-o...

Introduction: Association between high thyrotrophin receptor antibodies (TRAb) and relapse of thyroid cancer in Graves’ patients was reported previously. In this study, we aimed to investigate possible relation between TRAb and thyroid malignancies in patients with toxic multinodular (TMNG) and toxic nodular goiter (TNG).Methods: Thyroidectomized patients with a preoperative diagnosis of TMNG, TNG and euthyroid multinodular or nodular goiter (MNG/NG...

Introduction: The predictors of malignancy are important for decision of appropriate management in nodules with atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS). Our aim was to determine the ultrasonographical, clinical and biochemical predictors of malignancy in these patients.Methods: A total of 427 patients with Bethesda Category III (AUS/FLUS) thyroid nodules were included in this retrospective study. We d...

Introduction: We aimed to determine demographical, hormonal, ultrasonography(US) and cytological features of cases with neck lesions that are located outside the thyroid region and have similar echogenity with thyroid tissue.Method: Neck US reports of patients who underwent fine needle aspiration(FNAB) under US guidance in our clinic in a period of one year were reviewed retrospectively. Lesions having similar echogenity with thyroid tissue and defined a...
