AIMS AND BACKGROUND An increased incidence of neuroendocrine tumors in the last decade has been noticed worldwide. Our purpose was to study the characteristics, surgical approaches and outcome in patients with primary bronchopulmonary carcinoid tumors. METHODS Between 2001 and 2007, bronchopulmonary carcinoid tumors were removed in 11 of a total of 287 patients who underwent surgery for prima...

Bronchial carcinoid tumor comprises 1 to 3% of lung neoplasms. The common age of onset is mainly post-puberty although atypical carcinoid tumors occur at ages 44 to 55. Carcinoid tumors cause two groups of symptoms in patients: symptoms due to obstruction and symptoms due to the production and release of active neuropeptides. Histologically, carcinoid tumors are categorized into two groups of t...

Carcinoid tumors of Vater’s ampulla are the most common among the extremely rare primary ampullary neuroendocrine tumors, accounting for less than 0.35% of all gastrointestinal carcinoids and are frequently associated with Von Recklinghausen’s disease. Carcinoid tumors of Vater’s ampulla are difficult to diagnose preoperatively because of their relatively small size and submucosal location. Con...

In this study, 92% of patients' serums known to contain antibodies against islet cells, including the Juvenile Diabetes Foundation provisional reference serum, had antibodies reacting with gastrointestinal carcinoid tumors. Twelve percent of the control serums from healthy individuals bound to carcinoid cells, and 2% bound to islet cells. Seventy-five percent of the children with newly diagnose...

Introduction. Carcinoid tumors are low-grade tumors originating from endoderm and mostly involving the gastrointestinal system. However; they may be seen in any site within the gastrointestinal system. Case Presentation. A 69-year-old female patient. The results of blood tests were observed to be consistent with obstructive jaundice. A mass appearance was not encountered on tomographic examinat...

OBJECTIVE We sought to investigate the clinical and echocardiographic (echo) characteristics of metastatic carcinoid tumor in the heart. BACKGROUND Right-sided valvular dysfunction is the hallmark of carcinoid heart disease. Cardiac metastases are uncommon in carcinoid syndrome. Features of patients with metastatic carcinoid tumor involving the heart (MCH) have not been well described. METH...

Background Carcinoid tumors usually originate from the enterochromaffin cells located in gastrointestinal tract and bronchopulmonary system. They may rarely arise in the urinary bladder, where this can be eventually miscued as any other commoner bladder neoplasms. The current study was conducted to connote an uncommon clinicopathological presentation by a carcinoid tumor in the urinary bladder....

Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the enterochromaffin cells and secreting mainly serotonin. Neuroendocrine tumors (NETs) are found throughout the intestinal tract, the appendix and terminal ileum being the most common locations, and are classified by site of origin and by degree of differentiation, with well-differentiated lesions representing those...

BACKGROUND Mature cystic teratomas (MCTs) are common benign tumors occurring in the ovaries. Malignant transformation of teratomas (TMT) occurs in 1-3% of all MCTs, usually in postmenopausal women. Squamous cell carcinoma is the most common tumor type. Primary carcinoid tumors of the ovary are uncommon, representing only 0.3% of all carcinoid tumors and less than 0.1% of all ovarian cancers. ...
