Introduction: Medullary thyroid carcinoma (MTC) could be familial in 30% of cases. Here, we report a family of FMTC with rarely seen RET p.S891A mutation.Case presentation: A 49-year-old man presented with a single nodule in the left lobe of thyroid. Thyroid ultrasonography (US) showed a nodule and pathological cervical lymph nodes. There was no relevant family history. Fine-needle aspiration cytology (FNAC) of the nodule was consistent with a diagnosis ...

Objectives: Acromegaly may arise with several clinical presentations and cardiac involvement is the most important factor affecting the course of the disease.Case: A 32-years old man admitted to hospital complaining with shortness of breath. After initial evaluation he was diagnosed as ‘cardiac failure’. Cardiac evaluation revealed that he had ‘dilated cardiomyopathy’ with ejection fraction (EF) of 20%, global hypokinesia without valv...

Previous studies have shown increased hypoglycemia-associated cardiac arrhythmia and mortality in patients with type 2 diabetes and cardiovascular disease.In this study, we aimed to evaluate the response of gastrointestinal hormones and glucoregulatory hormones to the oral glucose tolerance test in patients who were diagnosed with reactive hypoglycemia and to evaluate the risk of arrhythmia with long-holter ECG measurements in patients with a diagnosis o...

Objectives: Pituitary gland is an uncommon site for metastasis of malignant tumors. Breast and lung are the most common cancer sites. Most pituitary metastases are asymptomatic, with only 7% symptomatic and central diabetes insipidus is the most common symptom.Case presentation: A 54 year-old woman presented with nause, emesis and diplopia to emergency department. Her relatives stated that she had poliuria, nocturia, polidipsia for three months. Her hist...

Background: Alstrom syndrome is a rare autosomal recessive genetic disorder characterised by vision loss, hearing loss, childhood obesity, insulin resistance and hyperinsulinemia, type 2 diabetes, hypertriglyceridemia, cardiomyopathy, and progressive pulmonary, hepatic, and renal dysfunction. Hyperinsulinemia develops early, and pancreatic islets show beta-cell proliferation, thus suggesting that both insulin resistance and increased insulin secretion might contribute to gluco...

Backgorund: Adrenal incidentalomas (AI) are lesions discovered incidentally on imaging without clinical symptoms or examination findings. AI can produce hormones in 5-30% of cases. Autonomic cortisol secretion (ACS) is the most common of these. Although ACS is asymptomatic, it increases the risk of metabolic disorders.Methods: Patients aged<18 years with adrenal adenoma and upper abdominal MRI who presented and were examined in the endocrinology outp...

Background: Hypoparathyroidism (HypoPT) is a rare condition that is characterized by hypocalcemia and hyperphosphatemia due to low or inappropriately normal serum levels of parathyroid hormone (PTH) for at least 6 months. The long-term complications of hypoparathyroidism indicate the necessity of screening them. In the follow-up of these patients according to hypoparathyroidism guidelines is recommended; calcium, phosphorus, albumin, magnesium, creatinine, and eGFR levels shou...

IntroductionHypercholesterolemia may develop due to primary and secondary causes. Diabetes mellitus, hypothyroidism, nephrotic syndrome and liver diseases are among the most common causes of secondary hyperlipidemia. Here, we will present a case with severe hyperlipidemia due to primary sclerosing cholangitis(PSC).CaseA 36-year-old male patient was admitted to our outpatient clinic due to severe hypercholeste...

However ACTH secreting adenomas are one of the most common functional pituitary tumors, subtypes such as Crooke cell corticotroph adenoma(CCCA) are relatively rare. We present here a patient with CCCA who had severe hypercortisolism mimicking ectopic ACTH syndrome. A 69 years old female patient admitted to emergency department after a fall. On cranial MRI,’a 3.5x2.5x3cm mass appearance with a sellar-suprasellar location, which is compressing the optic chiasm, expanding th...

Introduction: Disease control in acromegaly can be achieved by surgery, medical treatment, and radiotherapy either alone or in combination. The acromegaly patients whom tumour shrinkage cannot be provided or growth hormone levels do not decrease under multiple treatment modalities are designated as resistant acromegaly. We aimed in our study to evaluate the clinical features of resistant acromegaly patients and determine their responds to different treatment modalities.<p ...
