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...

Aim: Exophytic nodule refers to a nodule that sticks out of the normal thyroid boundary/outline. Other definition is a nodule with an acute angle between the lesion and adjacent thyroid capsule. In the literature, one study reported that thyroid nodules with exophytic configuration showed a high malignancy rate. We aimed to compare ultrasonographical features and cytopathologic results of exophytic and non-exophytic thyroid nodules.Material and method: T...

Introduction: Ocular changes and ocular symptoms may be encountered in patients with hypothyroidism and hyperthyroidism. However, the data concerning the effects of thyroid disorders on intraocular pressure (IOP), central corneal thickness (CCT), and retinal thickness (RT) are very rare. Here, we aimed to evaluate the alterations in IOP, CCT, and RT in patients with euthyroid autoimmune thyroiditis (AIT).Methods: Twenty-five subjects with euthyroid AIT w...

Introduction: Synchronous and asynchronous cases of acromegaly and other malignancies have been reported in literature. However, synchronous apperance of acromegaly and gastrointestinal stromal tumors (GIST) is encountered so rarely. We herein reported a case of synchronous acromegaly and GIST.Case report: A 59-year-old patient was investigated due to iron deficiency anemia. On the physical examination revealed enlarged hands and coarse facial feature; a...

Introduction: Adrenal failure due to tuberculosis is rarely seen nowadays. There are few reports in the literature suggesting that adrenal insufficiency may improve with anti-tuberculosis therapy during the active phase of the disease. Herein, we presented a case of reversible adrenal failure in a patient with active tuberculosis.Case report: A 50-years-old-female patient admitted to our clinics with the complaints of weakness and darkening of the skin. ...

Introduction: The cases of paragangliomas (PGLs) mimicking thyroid nodules were also reported in literature rarely. We will present a case of PGL (a carotid body tumor) that we initially evaluated as a thyroid nodule, and then diagnosed as a PGL.Case report: A 74-year-old woman was admitted due to a mass in the right side of neck growing rapidly within the last 1 month. Physical examination revealed a hard and painless mass with smooth surface, extending...

Introduction: Metastatic pituitary tumors are seen rarely and it is hard to differentiate them from the benign lesions of the gland. We have reported a case, with a known maxillary sinus tumor, detected to have a pituitary lesion coincidentally on PET-CT.Case: 45 years old male patient with a known history of relapsed maxillary sinus tumor has been referred to our clinics because of the pituitary lesion detected to have increased FDG involvement on PET-C...

Background: Generously supported by IPSEN)-->In this study we have aimed to calculate the QT dispersion in acromegaly patients and reveal its correlation with GH and IGF1.Materials and methods: Forty-one acromegaly patients were enrolled in the study. Another 41 patients with similar age, sex and comorbid disease distrubition have constituted the control group. We have evaluated the electrocardiograms (ECG) of ...

Aim: Thyroid pyramidal lobe and thyroglossal duct cysts were reported to be associated with increased risk of thyroid cancer. In this study, we aimed to evaluate ultrasonography (US) guided fine needle aspiration biopsy (FNAB) cytology results of pyramidal lobe and thyroglossal duct cysts.Material and methods: Patients with pyramidal lobe and thyroglossal duct cysts detected in US were included. Thyroid functions, thyroid autoantibodies, Tc 99m thyroid s...
