Introduction: Graves’ orbitopathy (GO) is a rare autoimmune inflammatory disease occurring in 25–50% cases of Graves’ disease (GD). It is associated with poor clinical outcomes, impaired quality of life and socio-economic status. Genetic, environmental and immunological factors are considered to play a role in the pathogenesis of GO, but the effects of neutrophil, lymphocyte counts as well as neutrophil-to-lymphocyte ratio on the pathophysiology of GO are still ...

Introduction: Von Hippel-Lindau (VHL) disease is an autosomal dominant disorder characterized by formation of tumors and cysts in various organs. Renal cancer and central nervous system angiomas (whose frequencies in VHL disease are estimated for 70% and 76% respectively) are considered main prognostic factors, with renal cancer being the most common cause of death. Neuroendocrine tumors of the pancreas occur in only 10 to 20% of VHL patients and are benign in the majority of ...

Adrenocortical carcinoma is an aggressive tumor of endocrine system with an annual incidence of 1–2 cases per million. The most significant prognostic factors are tumor size, disease stage at the time of putting the diagnosis and treatment method. Advanced age of the patient, and hormonal activity of the cancer are also related to poor prognosis.Materials and methods: In our study we collected data of 12 patients who were treated in Endocrinology Cl...

Introduction: Insulinoma is a rare form of a functional neuroendocrine tumor with an estimated incidence at 1–2 new cases per million persons per year. This infrequent endocrinopathy, frequently escaping standard disease course, constitutes a diagnostic challenge for every endocrinologist. Successful surgical resection of the lesion is the only available method that ensures patient’s full recovery.Case study: 53 years old patient with complaint...

Introduction: Calcium ions (Ca2+) play an essential role in process of correct β-cell insulin secretion. Hypocalcemia impairs insulin secretion leading to glucose metabolism disorders and insulin resistance.Case study: 62 -year old female patient with 18 years history of type 2 diabetes, treated with insulin, suspected of hypoparathyroidism, was admitted to the Department and Clinic of Endocrinology, Medical University of Lublin because o...

Introduction: Pituitary apoplexy is a rare endocrine disorder which can occur due to haemorrhage into pituitary gland. It is often associated with the presence of pituitary adenoma, uncommonly being the first clinical manifestation of an underlying tumour. It can cause hypopituitarism and diabetes insipidus. Pituitary adenomas are classified by their secretion properties as functional and clinically non-functioning, the latter, however, can exhibit positive immunostaining for ...

Introduction: Atypical pituitary adenomas are often characterized by rapid growth and massive invasion of the surrounding structures. Usually, they are associated with poor prognosis and high recurrence rate due to resistance to conventional therapies. When surgery and radiation are ineffective, alternative therapies remain the last line treatment. Lately, a novel chemotherapy with capecitabine and temozolomide was proposed as a highly effective and extending the life of the p...

Introduction: Diamond-Blackfan anemia (DBA) is a rare, inherited normocytic or macrocytic anemia due to aplasia of red cell lineage in the bone marrow. Patients with DBA are diagnosed with a hypocellular bone marrow with a significant absence of erythroid precursors typically in early childhood and require chronic treatment with corticosteroids and frequent blood transfusions. Chronic blood transfusions lead to iron-overload injury and DBA patients, therefore, require lifelong...

Introduction: Adrenal medullary hyperplasia (AMH) is a rare syndrome of catecholamine excess. Adrenal overgrowth is usually bilateral. Due to similar clinical signs, laboratory results and radiological adrenal picture, AMH can be misdiagnosed as pheochromocytoma. The only method that allows determining a proper diagnosis of AMH is pathologic examination. It is regarded as a precursor of pheochromocytoma and has been reported as a component of MEN2.Aim: T...

Introduction: Immunoglobulin-G4-related disease (IgG4RD) is a multidisciplinary problem due to plasmatic cells infiltration and areas of fibrosis in the affected tissues. In IgG4RD, elevation of serum IgG4 immunoglobulins is present. Clinically, the disease is mainly manifested as: autoimmune pancreatitis, salivary gland involvement, sclerosing cholangitis, lymphadenopathy, lachrymal gland enlargement, retroperitoneal fibrosis or orbital pseudotumor. The simultaneous involveme...
