Primary carcinoid tumour of the testis is extremely rare. We describe a case of testicular carcinoid, discuss the ultrasound appearances and differential diagnosis.

BACKGROUND Intrapulmonary carcinoid tumors (ICTs) are malignant, slow-growing tumors classified as either: i) typical, less aggressive, well-differentiated tumors or ii) atypical, more aggressive, poorly-differentiated tumors. Most typical carcinoid tumors originate in the central airway and present with symptoms related to bronchial obstruction. In contrast, atypical carcinoids tend to occur m...

BACKGROUND The management of patients with carcinoid heart disease poses two major challenges for the anaesthetist: carcinoid crisis and low cardiac output secondary to right ventricular (RV) failure. Carcinoid crises may be precipitated by the administration of catecholamines and histamine-releasing drugs. METHODS We analysed a series of 11 patients [six males, median (range) age 60 (42-73) ...

PURPOSE Metastatic neuroendocrine tumors secrete serotonin and other vasoactive substances that are responsible for carcinoid syndrome and carcinoid heart disease. We sought to evaluate the discriminatory utility of diagnostic biomarkers in determining the presence and severity of carcinoid heart disease in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS A cross-sectional...

A carcinoid crisis is a severe complication of the carcinoid syndrome that can arise in patients with advanced metastatic neuroendocrine tumors. It can be initiated by stress, catecholamines, and tumor manipulation. In this article, we report a case in which an injection with the catecholamine tracer 6-18F-fluorodihydroxyphenylalanine, used for PET, induced a carcinoid crisis. Octreotide can be...

A patient with a carcinoid tumour arising in a Meckel's diverticulum and presenting with acute small intestinal obstruction is described. Review of previously reported cases indicates that the initial clinical presentation of carcinoid tumours occurring in a Meckel's diverticulum is usually similar to that of appendiceal carcinoids. While most carcinoids in Meckel's diverticula present as incid...

Received June 2007 Accepted September 2007 INTRODUCTION Carcinoid tumors frequently develop in the gastrointestinal tract and the respiratory system.(1) Those originating from the kidneys are exceptionally rare. Less than 45 cases of primary carcinoid tumors of the kidney have been reported in the English literature, so far.(2-4) We herein report another case of primary renal carcinoid tumor fo...

Carcinoid tumours are often difficult to diagnose because of non-specific symptoms, mimicking those of irritable bowel disease of Crohn's disease. The authors describe a 57-year-old patient with clinical and radiological features, suggestive of Crohn's disease, in whom the diagnosis was proved to be a carcinoid tumour involving the terminal ileum. This case report illustrates that ileal carcino...

Am J Physiol Gastrointest Liver Physiol 289: G636–G642, 2005; doi:10.1152/ajpgi.00146.2005.—Gastrointestinal (GI) carcinoid cells secrete multiple neuroendocrine (NE) markers and hormones including 5-hydroxytryptamine and chromogranin A. We were intereste...

BACKGROUND Since Oberndorfer proposed the term "carcinoid" in 1907, over 100 years have passed. This attractive term was initially proposed for 6 cases of his own experience with 12 submucosal lesions in the small intestine.Oberndorfer summarized the characteristic features of these lesions as follows: (1) small in size and often multiple, (2) histologically undifferentiated with a suggestion o...
