Introduction: Giant and cystic catecholamine-secreting tumors are usually asymptomatic and detected incidentally during imaging. A simple mobilization of the tumor can cause the release of catecholamines into the blood and is therefore associated with high morbidity and mortality. Here, we aimed to present a patient with a 13 cm mass in the left adrenal gland and diagnosed as giant cystic pheochromocytoma.Case Report: A 62-year-old male patient presented...

Introduction: Extramedullary hematopoiesis (EMH) is most commonly seen in reticuloendothelial system tissues such as liver, spleen and lymph nodes. Rarely, it can be detected in non-hepatosplenic atypical localizations such as the adrenal glands. Although the underlying mechanism is not clearly elucidated, it is suggested that the adrenal glands have hematopoietic activity in the fetal period and EMH may develop from the remains here due to chronic anemia. We aimed to present ...

Introduction: Hemiballism is a rare hyperkinetic movement disorder characterized by involuntary, violent, coarse and wide-amplitude movements involving the ipsilateral arm and leg. Here, we aimed to present a case diagnosed as hemiballism due to non-ketotic hyperglycemia.Case Report: A 60-year-old female patient presented to the emergency department with involuntary movements in the right half of the trunk for 10 days. It was a large amplitude proximal e...

Introduction: Although ectopic ACTH syndrome (EAS) is most commonly seen in cancers with neuroendocrine differentiation, it is not a common condition in germ cell tumors. Here we report a rare case of EAS due to metastatic germ cell tumor.Case report: A 53-year-old male patient presented with fatigue, weakness, swelling in both legs and weight loss for 3 months. He had type 2 diabetes and no history of smoking or alcohol. In the physical examination, the...

Introduction: Pituitary apoplexy is a life-threatening clinical syndrome that develops as a result of bleeding or infarction in a pituitary adenoma. Here, we aimed to present a case of cabergoline-resistant macroprolactinoma who developed pituitary apoplexy.Case Report: A 40-year-old male patient presented to neurology 2 years ago with severe headache. Brain magnetic resonance imaging (MRI) revealed a 15.5×18×21 mm macroadenoma in the pituitary...

Introduction: Germinomas, which are the most common germ cell tumors of the central nervous system, may present with different symptoms depending on the location and are localized in the 20-30% suprasellar region. Here, we aimed to present a case of suprasellar germinoma with central diabetes insipidus, hypogonadism and secondary adrenal insufficiency.Case Report: A 27-year-old male patient presented with dry mouth, polydipsia, polyuria and nocturia for ...

Objectives: Primary thyroid lymphoma constitutes 0.5-5% of all thyroid malignancies. Its incidence is two per million persons. Patients usually present with rapidly growing masses in the thyroid their sixth-seventh decades. The disease is frequently accompanied by chronic Hashimoto’s thyroiditis. Most tumors are B-cell derived non-Hodgkin’s lymphoma.Case report: An 84-year-old male patient presented with a palpable swelling in the neck. Ultraso...

Background: Adrenal carcinoma is rare endocrine cancer. Survival time is short and primary treatment is surgery.Methods: Four patients with histopathologically diagnosed as adrenal carcinoma between 2007 and 2013 were evaluated retrospectively.Results: Two of the patients were female and others were male. Their ages were 39, 50, 55 and 61 respectively. All the patients were admitted to the hospital with abdominal pain. Tumor diamet...

Introduction: Insulin resistance is the decrease sensitivity of tissues in the body to insulin effect. Obesity, advanced age, sedentary life and smoking are the factors leading to an increase in insulin resistance. In our study, we aimed to evaluate the relationship between the insulin resistance and smoking in individuals without advanced age, obesity, high blood glucose levels and hypertension.Materials and methods: We included in this study 100 patien...

Introduction: Deposition of amyloid substance within the thyroid gland causing clinically appearent enlargement of the gland is described as amyloid goiter. Although microscopic deposition of amyloid substance in thyroid gland is common in systemic amyloidosis, occurence of amyloid goiter is rare.Case: A 55 years old male patient, who had been diagnosed with multinodular goiter for 10 years, was admitted to our clinic with complaint of increased swelling...
