Atypical thymic carcinoid is an extremely rare thymic neuroendocrine tumor derived from the neuroendocrine system. The aims of this paper were to investigate the clinical features of atypical thymic carcinoid and collate information and experience to improve the diagnosis and treatment of this disease. We describe three cases of atypical carcinoid of the thymus; clinical features, pathological ...

PURPOSE Carcinoids are neuroendocrine tumors and most frequently occur within tissues derived from the embryonic gut. These tumors can occur in any organ site but are rare in the testis. The cell type giving rise to testicular carcinoid is unknown. We hypothesized that testicular carcinoid may have a germ cell origin. EXPERIMENTAL DESIGN We describe our analysis of protein and genetic markers...

Purpose: This study aimed to investigate the expression of the ErbB family of receptor tyrosine kinases in pulmonary typical carcinoid and atypical carcinoid tumors and to understand the role of epidermal growth factor receptor (EGFR) signaling in pulmonary carcinoid tumor proliferation. Experimental Design: Surgically resected typical carcinoid (n = 24) and atypical carcinoid (n = 7) tumor tis...

OBJECTIVE To report a case of mixed adenocarcinoma and carcinoid in the gastrointestinal tract. CLINICAL PRESENTATION AND INTERVENTION A 52-year-old man presented with a mass at the base of the appendix. On microscopic examination of the tumor, mixed adenocarcinoma and carcinoid was identified. The carcinoid component was insular/trabecular in morphology, and the epithelial component revealed...

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...

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...

Meckel’s diverticulum is a common pathology in children and rare adults. We present case of 79-year-old patient which significant gastrointestinal bleeding, whose paraclinical explorations confirmed fatty tumor the terminal ileum. The exploratory coelioscopy revealed Meckel complicated intestinal invagination, resected at same time with resection extracorporeal anastomosis by mini coelio-guided...

The first report of an association between a carcinoid tumor and a specific syndrome was reported by Biorck and associates in 1952. 6 Since that time, literature on the carcinoid syndrome has appeared more frequently. In 1976, Mason and Steane published two review articles on the subject which have served as reference guides for anesthesia personnel.6' 7 Fewer than 50 cases of the carcinoid syn...

Carcinoid heart disease was first described in 1954. It develops over 70% of carcinoid syndrome patients. Up to 20% patients with have pronounced at diagnosis. Cardiac involvement is usually well tolerated by Symptoms are associated secretion serotonin, tachykinin and other vasoactive substances the systemic circulation. Deposition fibrous tissue along tricuspid annulus leads ring constriction ...

Rectal carcinoids comprise 12.6% of all carcinoid tumors and represent the third largest group of the gut carcinoids. A 64-year-old woman was diagnosed as high-grade neuroendocrine carcinoma. She had liver, bone, and bone marrow metastasis. Carcinoid syndrome was diagnosed due to diarrhea, nausea, vomiting, tachycardia, and high level of 24-hour urinary 5-hydroxyindoleacetic acid (160 mg/24 hou...
