Background: Hypogonadism is related to additional endocrine abnormalities. Thyroid abnormalities may be common in hypogonadism patients, although this association is not clear.Objective: In this study, we examined the incidence of thyroid disorders in hypogonadisms.Methods: A case–control study of 68 hypogonadal patients and 74 age-matched healthy controls from the general population was conducted. Thyroid function, thyroid vo...

Introduction: Primary hyperparathyroidism (PHPT) is a common endocrine disorder that is characterized by hypercalcemia and elevated or normal levels of parathyroid hormone (PTH). Most PHPT cases are incidentally discovered when routine laboratory analysis reveals hypercalcemia. PHPT should be considered in any person with elevated serum calcium (Ca) levels and no clear evidence of malignancy. Serum phosphorus (P) is low due to the phosphaturic effects of PTH and mostly in the ...

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...

Background: Although high levels of calcitonin suggest neoplastic proliferations such as medullary thyroid carcinoma, C cell hyperplasia and some neuroendocrine tumors, systemic diseases and drugs may also elevate calcitonin. Although calcitonin is not as effective as PTH, it has got a role in calcium hemoastasis. Supraphysiological calcitonin level can lead to hypocalcemia.Case presentation: A 57-year-old male patient was diagnosed with epilepsy with co...

Ectopic secretion of corticotropin(ACTH) by nonpituitary tumors accounts for 10–15% of ACTH dependent Cushing’s syndrome (CS). Generally it is difficult to localize the ACTH secreting tumor by conventional imaging methods because these tumors are often small in size. Here we present a case of ectopic ACTH syndrome diagnosed with octreotide scan.Case: A 26-year-old male patient presented with moon face, purplish striae, supraclavicular fat pads ...

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...

Giant cell granuloma is a skeletal manifestation seen now rarely in hyperparathyroidism due to early recognition of the disease. Lesions usually occur in the areas of intense bone resorption. They can affect mandible, maxilla, clavicle, ribs and pelvic bones. Most of the patients who have primary hyperparathyroidism are asymptomatic and are discovered incidentally during laboratory examinations. Here, we represent a female patient who was referred to endocrinology clinics beca...

The classic clinic manifestation of primary hyperparathyroidism (PHPT) is osteitis fibrosa cystica, a severe skeletal disease characterized by brown tumors, bone cysts and deformities, due to extremely elevated bone resorption elicited by continuously high parathyroid hormone (PTH) levels. In cardiovascular system there may be shortened QT interval, deposition of calcium in heart valves, coronary arteries, and myocardial fibers. Here, we report a case with PHPT, who have anore...

Pituitary adenomas which co-secrete GH and TSH accounts for <0.2% of all adenomas of the pituitary. Symptoms of hypertyroidism are usually masked by clinical manifestations of acromegaly. Here, we have reported the result of the primary one year long medical therapy in a case who was diagnosed to have adenoma co-secreting GH and TSH.Case: Seventy-years-old female patient has admitted with the complaints of excessive sweating, enlargement of hands and...

Mixed medullary-follicular carcinomas (MMFC) of the thyroid are rare tumors which represents <0.15% of all thyroid tumors showing the morphological and immunochemical properties of both parafollicular and follicular cell lineages. Cases were immunoreactive for both calcitonin and thyroglobulin.Case 1: A 25-year-old female patient referred us for evaluation of a thyroid mass located on the left lobe. Ultrasonography (US) revealed 38 mm solid isoechoic...
