Background: Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is a newly described indolent thyroid tumor with well-defined histopathological diagnostic criteria. Even though the histopathologic features and diagnostic criteria for NIFTP are well-established, preoperative diagnosis using sonographic or fine needle aspiration findings has yet to be confirmed. The aim of this study is to compare the clinical, sonographic, and cytological charac...

The most common reason for the rare condition of hyperinsulinemia-related hypoglycaemia is insulinoma, a tumor of pancreatic islet cells. However, nesidioblastosis characterized by diffuse or focal hyperplasia of the pancreatic islet cells is the most common cause of hyperinsulinemic hypoglycemia in newborns. Nesidioblastosis seen in newborns is now called ‘persistent hyperinsulinemic hypoglycemia of infancy’ (PHHI) while the condition in adults is called ‘nonin...

Dopamine agonists are the treatment of choice for prolactinomas and surgery is warranted only when the response to medical therapy is poor, not tolerated, or in those with compromised vision or with extensive invasion. We describe the two cases of a giant prolactinoma treated with cabergoline alone and next to surgery and gamma-knife.Case 1: A 30-year-old man admitted with headache and visual defect, cranial magnetic resonance imaging (MRI) revealed a in...

Introduction: The involvement of certain organs such as the adrenal gland is rare in non-Hodgkin’s lymphoma (NHL). Although lymphomas can involve virtually all extranodal organs, different organs show different frequency of involvement. Adrenal gland involvement is usually bilateral. We report that a rare case of unilateral adrenal involvement of diffuse large B-cell lymphoma presenting with abdominal pain.Case: A 64-year-old-man presented with abdo...

A 27-year-old woman with had sweating flushing attacks for three years prior to pregnancy, but did not follow with any medical examination. At 12th gestational week, hypertension was detected and alpha-methyldopa was started, no abnormal findings were found in the routine examinations, in the 24-h holter study, blood pressure values (using alpha-methyldopa) were found to be higher than 144/99 (general), 147/101 (awake) and 134/92 mmHg (sleep). 24-hour urinary levels of catecho...

Introduction: Hypervitaminosis D is a rarely reported condition. It may be observed more frequently because of the recent increase in supplement use of vitamin D. Herein, we report a case of vitamin D intoxication which was the first case with this high level of calcium as we searched the literature.Case report: A 57-year old hypertensive woman admitted to our emergency room with symptoms of constipation, loss of appetite and confusion. Blood pressure, h...

Introduction: Primary hyperparathyroidism (PHPT) commonly goes unrecognized due to the physiological changes of pregnancy.PHPT is associated with significant maternal and fetal morbidity and mortality. Current evidence supports parathyroidectomy is the main treatment, performed preferably during the second trimester, when the serum calcium is above 11–mg/dl. We report the clinical course of a woman with newly diagnosed gestational PHPT who refused minimally invasive parat...

Introduction: Glucagonomas are rare neuroendocrine tumours (NET). Glucagonoma syndrome is often misdiagnosed as other skin lesions by clinicians due to typical clinical sign of necrolytic migratory erythema (NME). In this article, we report a metastatic glucagonoma case diagnosed at adult age with distinct features of the disease.Observations: We present a case of a 28-year-old female patient. The initial rash appeared in early 2019 and was mostly on low...

Primary Hyperparathyroidism is a common endocrine disorder characterized with high parathyroid hormone (PTH) and calcium (Ca) levels. Although most of the patients are asymptomatic, some patients may be presented with renal, gastrointestinal, musculoskeletal, neurologic or cardiovascular signs associated with hypercalcemia or elevated parathyroid hormone related findings such as bone disease, nephrolithiasis, hypophosphatemia increased production of calcitriol, hypomagnesemia,...

Background: Brown tumor of bone is a non-neoplastic lesion resulting from abnormal bone metabolism in hyperparathyroidism. Brown tumor, as the only and initial symptom of normocalcemic primary hyperparathyroidism is extremely rare.Case presentation: A 69-year-old female patient was admitted to the hospital with a mass in the right thigh. A mass lesion of the right distal femur with bone and soft tissue infiltration was observed in the lower extremity mag...
