Introduction: We present the case of coincidence of pheochromocytoma and aderenocortical carcinoma at the same adrenal gland in patient with neurofibromatosis. That kind of tumors coincidence origin from different blastodermic layers is extremely rare.It is broadly known that pheochromocytoma is rare neoplasm, occurs in 0.1% of hypertensive individuals. Pheochromocytoma may occur sporadically or in certain familial syndromes, including multiple endocrine...

Background: NETs are rare tumours arising from dispersed neuroendocrine system. Nevertheless, their estimated prevalence increased lately, mostly due to progress in imaging, biochemical and histopathological diagnostics.The aim of the study was to present the characteristics of the NETs patient surveyed in our Endocrinology Department since 2000.Material and methods: One hundred and fifty-eight patients (males – 42.4%, females...

Aim of the study was1. To assess the thyroid function in pregnancy in the course of effective iodine prophylaxis model introduced in 1997, based on obligatory salt iodization.2. To exam glucose tolerance and insulinemia in pregnancy.Methods: TSH, fT4, aTPO, urine iodine concentration, usg thyroid volume and homogeneity, glucose and insulin during OGTT, blood pressure, BMI, and thyroid function and glucose met...

Despite a wide spectrum of imaging diagnostics, GEP-NETs often stay undetectable until the time of dissemination. Removing of a primary tumour together with disseminated lymph nodes even with the presence of liver metastases is the most appropriate treatment to delay progression of the disease. SRS followed by RGS gives a possibility to detect occult GEP-NET intra-opratively. 99mTc-HYNIC/EDDA-octreotate, a somatostatin analogue with high affinity to sst2 was applied...

Introduction: Neuroendocrine tumors secreting ACTH are a rare cause of Cushing’s syndrome.Diagnostic and therapeutical difficiulties might be caused due to different clinical picture of of neuroendocrine tumors.Patients, diagnostic and therapeutic approach: During 2004–2005 2 female patients 32-years old AL and 67-years old ZS were hospitalized in Endocrinology Department due to severe hypercorticism signs and symptoms. I...

BackgroundSilent somatotroph pituitary tumours are very rare, representing only 2-4% of all pituitary tumours in surgical series. Little is known about the course of the disease and efficacy of possible treatment modalities.Presentation of the caseA male, born in 1990, was first admitted to the hospital at the age of 15, due to sudden ptosis of the right eye and headaches, present for 1 year before the diagno...

Introduction: Measurement of the baseline level of 17-hydroxyprogesterone (17OHP) is a screening test for NCAH, a less severe form of congenital adrenal hyperplasia.Aim: A real-life verification of the currently adopted 17OHP threshold (≥2.0 ng/ml) at which the further diagnostic (cosyntropin stimulation test) should be performed.Material and methods: The study included 400 patients (385 females and 15 males) referred to the ...

Introduction: 2-[18F]FDG PET/CT, commonly used for neoplastic lesions detection, also allows assessment of the severity of the inflammatory processes. Moreover, glucose uptake in spleen and bone marrow may be a useful biomarker of systemic inflammation. Patients with Cushing syndrome demonstrate many metabolic changes involving muscles and fat tissue. Some mechanisms are known, but their relationship to glucose metabolism is not well investigated. Our study aimed to correlate ...

Aim: To investigate T2-signal intensity (SI) and histopathological characteristics of the somatotroph PitNETs (S-PitNET).Methods: 41 out of 109 consecutive patients with newly diagnosed acromegaly and available histopathological results were included. 36 results contained the electron microscope examination. Tumors were divided into 3 SI groups: hyperintensive (HyPER), isointensive (ISO) and hypointensive (HyPO). SI was assessed qualitatively using Visua...

CHEK2, located on chromosome 22q, is a tumor suppressor gene. Its’ pathogenic variants are often associated with a tumor predisposition syndrome 4, with an increased risk of breast, prostate and colorectal cancers. There are some reports of an increased risk of papillary thyroid cancer (PTC) in carriers of the CHEK2 pathogenic variants. Current guidelines, however, do not recommend general screening of TC patients. The study assessed the prevalence of pa...
