Introduction: Over expression of somatostatin receptors (SSTR) is the characteristic feature of well differentiated neuroendocrine neoplasms (NENs). We present two patients with well differentiated NENs of the large intestine with negative SRS and without SSTR expression confirmed with immunohistochemical (IHCH) examination and symptoms of carcinoid syndrome with good clinical response to the therapy with long acting somatostatin analogs.Case reports: 53...

Introduction: Serotonin producing neuroendocrine tumors are usually well differentiated, small lesions localised in the small intestine. Visualisation of the primary tumor might be difficult due to its small size.Case report: A 52 years old man presented with diarrhoea and flushes. Ultrasound examination and computed tomography of the abdomen revealed numerous lesions in the liver. Gastroscopy, colonoscopy and magnetic resonance imaging did not reveal th...

Introduction: Despite development of diagnostic and therapeutic possibilities pancreatic neuroendocrine tumours remain still a clinical challenge.Case report: A 31-year-old woman after cholecystectomy performed in 2007. MRI performed in November 2008 due to abdominal pain revealed tumour of the pancreas – 35×42×32 mm. In May 2009 patient underwent partial excision of the pancreas. On histopathological examination neuroendocrine tumour NET ...

Introduction: Peptide receptor radionuclide therapy is indicated in case of patients with disseminated neuroendocrine tumors and is usually considered as palliative treatment.Case reports: 55 years old man diagnosed with tumor of the pancreatic head. On laparotomy performed in June 2012 tumor was stated unresectable. Histopathological examination revealed the mixed adeno-neuroendocrine cancer (MANEC). Patient was qualified to chemotherapy with gemcitabin...

Introduction: Pancreatic neuroendocrine tumors (pNETs) are a heterogeneous group with various treatment options depending on grading, staging, and presence of symptoms related to hormonal secretion. Their incidence significantly increased over the past decade and nowadays constitutes 30% of all NETs of the gastrointestinal tract. Despite the evidence of a different malignancy potential of PNETs G2, postoperative management is the same in all patients. Ai...

: The observed increase in the incidence of Hashimoto’s thyroiditis (HT) requires research on factors that may affect its development. One of them may be vitamin D deficiency which is an epidemiological problem all over the world.Aim: The assessment of influence vitamin D deficiency on the HT activity.Material and methods: 310 people were enrolled in the study: 155 patients with HT (a-TPO and/or a-TG positivity)-144 women (93%...

Introduction: Based on cancer registries, the risk of second primary malignancies in patients with DTC increases by 30%. In our case report we aimed at understanding the patomechanism of metachronous primary tumours in patients with thyroid cancer.Case: In a 71-year old female surgery of nodular goitre (1988), followed by papillary thyroid cancer (pT3NxMx) surgery (2008) and complementary 131-I treatment (2009), were performed. In diagnostic WBS (2010) n...

The observed increase in the incidence of Hashimoto’s thyroiditis (HT) requires the research on environmental factors that may initiate or model its course. There have been reports of the impact of vitamin D3 deficiency on HT development.Objective: To assess the degree of deficiency of 25OHD3 and the relationship between the disease duration and 25OHD3 levels in patients with HT.Material and methods: 310 people were enrolled i...

Background: PRRT is an effective treatment option (especially for controlling disease progression)for disseminated neuroendocrine tumors (NETs), with good expression of the somatostatin receptors. Despite significant progress in NET personalized management, searching for novel predictive and prognostic factors of response to PRRT is crucial for more effective follow-up, better treatment choices leading to more favorable final outcome. Some recent studies indicate that the resp...

Cushing syndrome due to ectopic (adrenocorticotropic hormone) ACTH secretion (EAS) constitutes approximately 10% of Cushing’s syndrome (CS). In this group only in about 5% cases pheochromocytoma is the source of ACTH.We present two patients with EAS by pheochromocytoma.1. A 70 year-old woman with 3-months history of malaise, weakness, abdominal pain, loss of weight and appetite, hypertension and diabetes mellitus. One month ea...
