Introduction: Acromegaly is a chronic disease caused by excessive secretion of growth hormone (GH), and as a result, of insulin-like growth factor-1 (IGF1). Although controversial, frequency of both benign and malignant neoplasm formation is thought to be increased in acromegalic patients. Pleomorphic adenoma is the most common arising tumour from the parotid salivary gland. Here we report the case of a 33-year-old woman with acromegaly and also who presented with a swelling o...

Introduction: Xantoma disseminatum (XD) is a rare non-Langerhans cell histiocytosis (NLCH) which is often resistant to treatment. In this report, we presented a case with extensive cutaneous, hypothalamohypophysial, cerebral and gastrointestinal system involvement, which responded well to cyclophosphamide.Case: A 16-year-old female patient admitted to our hospital with the complaints of amenorrhoea, weight gain, polidipsia, poliuria, yellow-brownish papu...

Introduction: Leri–Weill dyschondrosteosis (LWD) is a rare autosomal dominant dyschondrosteosis characterised by Madelung deformity and mesomelic dwarfism. Majority of cases are associated with haploinsufficiency of the short-stature homeobox-containing (SHOX) gene. Here we report a patient with LWD and diabetes mellitus (DM).Case report: A 31 years old man applied with polyuria and polydipsia. He did not have any chronic disease. In family history,...

Introduction: Normal or elevated TSH level in the presence of elevated T4 is defined as ‘inappropriate TSH syndrome’. Two main clinical conditions that can lead that syndrome are TSH-secreting adenoma (TSHoma) and resistance to thyroid hormone (RTH). Making the correct diagnosis is crucial in order to decide the most appropriate treatment option. Herein we presented clinical and laboratory data of seven patients who were hospitalised for the differential d...

Aim: Vitamin D deficiency is reported as a risk factor for the development of diabetes in several epidemiologic studies. In this study, we investigated the frequency of 25-OH vitamin D deficiency in type 2 diabetes and the relationship between 25-OH vitamin D deficiency and microvascular complications.Materials and methods: Retrospectively, medical records of 557 type 2 diabetic patients admitted to the Endocrinology Outpatient Clinic in January–Mar...

Case: A 30-year-old man with hypoparathyroidism has been treated with calcitriol and calcium for 2 years, admitted hospital with persisting diarrhea. An endoscopic operation is planned. But when he was waiting for this examination as outpatient condition, he had a convulsion and had been taken in hospital by parents. Initial laboratory analyses revealed that he was hypocalcemic (total calcium of 6 mg/dl) and parathormone (PTH) 8 pg/ml, phosphorus 5.7 mg/dl, and magnesium 2 mg/...

Introduction: Major factor that modulates the PTH secretion is serum Ca level. Paratyhyroid gland also receives direct autonomic innervation. To date, measurement of several hormones such as cortisol,prolactin, renin and aldosteron were found to be affected by changing the posture from recumbent to the upright position. In the present study, we aimed to investigate postural change of PTH in normal individuals and patients with primary hyperparathyroidism (PHPT).<p class="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. ...

Background: Differentiated thyroid cancer is the most frequent thyroid tumor. Combinations of follicular carcinoma and papillary carcinoma are seen. Functional pituitary adenoma coexisting with differentiated thyroid carcinoma was reported previously in literature. We report a 47-year-old women with three different synchronous endocrine tumors; papillary thyroid cancer, follicular thyroid cancer, and prolactinoma.Case: A 47-years-old female patient was a...

Introduction: Viruses and virus-induced lymphokines may have an important role in the pathogenesis of autoimmunity. The occurrence and significance of autoimmune manifestations after the administration of viral vaccines remain controversial. Herein we have represented a case who developed type 1 diabetes 1 month after vaccination for measles in military.Case: A 25-year-old male patient admitted to our clinics with the complaints of polyuria, poydipsia, a...
