Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age...

Primary testicular carcinoid tumours (TCT) are very rare, and a large tumour size and the presence of carcinoid syndrome predict a malignant course. Histologically, it is difficult to differentiate between benign and malignant TCTs. We report a case of a primary pure TCT with an unusual presentation in a 23- year-old man, who had an asymptomatic, enlarged scrotum on the right side for 7 years. On gross examination, the tumour was 9.6 cm in diameter. The Ki-67 labelling index was 19.8%. High inguinal orchidectomy was performed, and 30 months after surgery the patient remains asymptomatic...

Acromegaly is a hormonal disorder that arises when the pituitary gland secretes excess growth hormone (GH), which in turn stimulates a concomitant increase in serum insulin-like growth factor 1 (IGF-1) levels. Gastroenteropancreatic neuroendocrine tumours (GEP-NET) constitute a heterogeneous group of tumours that can secrete serotonin and a variety of peptide hormones that may cause characteristic symptoms known as carcinoid syndrome, or other symptoms and hormonal hypersecretion syndromes depending on the tumour's site of origin...

BACKGROUND: The majority of patients with neuroendocrine tumor liver metastases (NELM) present with multifocal disease and are not surgical candidates. We present our 20-year experience with transarterial chemoembolization (TACE) using streptozotocin (STZ) in patients with initially unresectable NELM. METHODS: Patients with unresectable NELM treated with TACE using STZ at a single institution from 1995 to 2015 were identified after institutional board approval. Imaging was independently reviewed by a radiologist to evaluate for RECIST 1...

INTRODUCTION: Neuroendocrine tumors(NETs), once thought rare, are increasing in frequency in most countries and receiving increasing-attention. NETs present two-treatment problems. A proportion is aggressive and a proportion has a functional, hormone-excess-state(F-NET) each of which, must be treated. Recently, there have been many advances, well-covered in reviews/consensus papers on imaging-NETs; new, novel anti-tumor treatments and understanding their pathogenesis. However, little attention has been paid to advances in the treatment of the hormone-excess-state...

INTRODUCTION: Ovarian neuroendocrine tumors are extremely rare. In the ovary, the term of neuroendocrine tumor is usually related to carcinoid tumors although it may be sometimes applied to neuroendocrine carcinomas of non-small cells or small cells cancers usually occurring in the lungs. These carcinoid tumors may develop de novo or from other tumors including teratomas. CASE REPORT: We report a patient who presented with an ovarian carcinoid tumor developed, near or from a dermoid cyst, which was original by its mode of discovery in the dermatology department...

PURPOSE: Peptide drugs for antineoplastic therapies usually have low oral bioavailability and short in vivo half-lives, requiring less preferred delivery methods. Lanreotide depot is a sustained-release somatostatin analog (SSA) formulation produced via an innovative peptide self-assembly method. Lanreotide is approved in the USA and Europe to improve progression-free survival (PFS) in patients with unresectable gastroenteropancreatic neuroendocrine tumors (GEP-NETs) and also approved in Europe for symptom control in carcinoid syndrome associated with GEP-NETs...

INTRODUCTION: Lung neuroendocrine large-cell carcinoma (LNELCC) is a rare tumour with a poor prognosis. There are very few guidelines for LNELCC treatment but a better knowledge of its biology could improve the treatment and prognosis of this malignancy. OBSERVATIONS: We present the cases of 2 patients who presented initially with early stage carcinoid tumours treated with surgery. Both patients had further new neuroendocrine disease diagnosed because of intermittent carcinoid syndrome, predominantly occurring at the same time as menstruation...

Patients with well-differentiated neuroendocrine tumours may develop carcinoid syndrome (CS), which is characterised by flushing, abdominal cramps, diarrhoea, and bronchospasms. In this scenario, long-term secretion of vasoactive substances-serotonin, tachynins, and others, may induce fibrogenic responses in local or distant tissues, leading to complications such as carcinoid heart disease (CHD), mesenteric and/or retroperitoneal fibrosis. Rare cases of lung/pleural fibrosis and scleroderma have also been described...

Carcinoid heart disease presents as right-sided heart failure attributable to the dysfunction of the tricuspid and pulmonary valves. Although surgical valve replacement is the mainstay of treatment when patients become symptomatic, it is associated with substantial perioperative mortality rates. We present a case of severe pulmonary valve stenosis secondary to carcinoid heart disease, treated successfully with percutaneous valve replacement. A 67-year-old man with severe pulmonary valve stenosis was referred to our center for pulmonary valve replacement...

BACKGROUND: Campylobacteriosis caused by Gram-negative bacteria of the genus Campylobacter (mainly C. jejuni and C. coli) is one of the most common gastrointestinal zoonotic infections with increased incidence in humans worldwide. The typical symptoms are severe abdominal cramps, diarrhea and sometimes fever. The clinical course of Campylobacter infection is mainly mild and after one week self-limiting, but can take several weeks in some rare cases. However, patients with neuroendocrine tumors in the gastrointestinal tract, a neoplasm of enterochromaffin/neuroendocrine cell origin, can develop severe diarrhea during progression of tumor growth caused by hormonal excess due to the tumor...

The biogenic amine serotonin (5-HT) is a multi-faceted hormone that is synthesized from dietary tryptophan with the rate limiting step being catalyzed by the enzyme tryptophan hydroxylase (TPH). The therapeutic potential of peripheral 5-HT synthesis inhibitors has been demonstrated in a number of clinical and pre-clinical studies in diseases including carcinoid syndrome, lung fibrosis, ulcerative colitis and obesity. Due to the long half-life of 5-HT in blood and lung, changes in steady-state levels are slow to manifest themselves...

Colorectal carcinomas (CRC) were initially thought to be rare in Africa including Nigeria, but recent studies have shown a reverse trend in our environment. This study is aimed to identify the clinical and pathological characteristics of CRC diagnosed between July 2006 and June 2015 in the University of Uyo Teaching Hospital, and a Private Specialist Laboratory, Uyo, Akwa Ibom State, Nigeria. All histological diagnosed cases of CRC seen in the two laboratories (University teaching and a private facility) in Uyo, Akwa-Ibom state, Nigeria during the study period were retrieved noting their bio-data, pathological and clinical variables...

BACKGROUND: Neuroendocrine tumors (NETs) have a propensity to metastasize to the liver, often resulting in massive tumor burden and hepatic dysfunction. While transarterial chemoembolization (TACE) is effective in treating patients with NET metastatic to the liver, there are limited data on its utility and benefit in patients with large hepatic involvement. The aim of our study was to determine the clinical benefit and complication rate of TACE in patients with massive hepatic tumor burden...
