Background: Pulmonary CARCINOID TUMOR is a low-grade malignant neoplasm comprised of neuroendocrine cells. The aim of this study was to determine the clinical features; radiological and bronchoscopic findings, as well as treatment in patients.Materials and Methods: The hospital records of 21 patients with pulmonary carciniod TUMOR, who admitted to NRITLD between 1995 and 2001, were evaluated.Results: 19 patients had typical and 2 had atypical CARCINOID TUMOR. Male to female ratio was 1.1. The mean age ± SD was 39.33 ± 16.31.Cough (80.9%) was the most common presenting symptom. 16 patients had abnormal chest radiography. The diagnosis was made using bronchoscopy and biopsy. Most of the TUMORs arose in main bronchi. Surgery with or without endobronchial laser therapy was the treatment of our patients. Lobectomy (47.3%) was the most common procedure.Conclusion: surgery with or without laser therapy has a favorable outcome in pulmonary CARCINOID TUMORs.

Introduction: Neuroendocrine TUMORs are classified as rare TUMORs that are mostly seen in lung or gastrointestinal tract and can cause many specific sign and symptoms such as flushing, diarrhea, heart failure, tachycardia, emesis, and bronchoconstriction. In this case, the TUMOR is located in gallbladder with classic presentations. Case presentation: A 59 year-old female attended to our clinic with nausea and vomiting, heartburn, weight loss and flushing. The patient’ s ultrasound showed a hypo echo and heterogenic mass (24×36 mm) in the anterior wall of gallbladder which continued to the common hepatic duct and the CT scan reported a 40×21 mm mass like lesion in porto-hepatic area with pressure effect on distal of gallbladder and cystic duct suspicious for lymphadenopathy. The postoperative pathological findings were compatible with typical perineural CARCINOID TUMOR. Conclusion: CARCINOID or neuroendocrine (NETs) TUMORs are a type of slow growing TUMORs that are typically originated from several places of the body and usually begin in gastrointestinal (GI) tract or lung. CARCINOID TUMOR is a rare GI tract disease which consists about 1% of GI tract TUMORs. The NETs of gallbladder are very rare. This is necessary for surgeons to consider rare types in order to conduct proper management for this condition.

CARCINOID TUMORs frequently develop in the gastrointestinal tract and the respiratory system. 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.

Neuroendocrine TUMORs of the larynx comprise a rare group of TUMORs categorized as typical CARCINOID, atypical CARCINOID, small-cell neuroendocrine carcinomas, and paragangliomas. Atypical CARCINOID type occasionally denotes CARCINOID syndrome. Typical CARCINOID is extremely rare. The primary diagnosis is based on light histochemical studies that should be confirmed by immunocytological and/or ultrastuctural investigation. The different biological behaviors of these TUMORs lead to a specific diagnosis of paramount importance. 

Introduction: CARCINOID TUMOR in trachea is rare, and in 25% is asymptomatic. Cough is the most common symptom and some times have similar symptoms such as chronic obstructive pulmonary disease. The best method of treatment is surgical resection and recurrency after resection is rare. In this study we report a 47 year's old man with chronic cough and dyspnea that treated with bronchodilator as COPD but without recovery. In evaluation with chest X. Ray, CT scan and bronchoscopy CARCINOID TUMOR was diagnosed and surgical resection performed. There was no recurrency or complication in 5 years follow-up.

CARCINOID TUMOR of lung with Cushing’s syndrome is a rare condition. We report a 38-year-old man, with a 28-month history of Cushing’s syndrome presented with hypertension, diabetes mellitus, decreased libido, muscle weakness and fatigability, moon facies, buffalo hump, truncal obesity, cutaneous striae, and easy bruisability. Diagnosis was made by measurements of ACTH (149 pg/mL) and cortisol levels (36 μg/dL) and computerized tomography of the chest.

CARCINOID TUMOR is a slow-growing type of neuroendocrine TUMOR, originating in the enterochromaffin cells and secreting mainly serotonin.The diagnosis is based on clinical symptoms, hormone levels, radiological and nuclear imaging, and histological confirmation. The clinical symptoms are characterized by flushing, diarrhea, abdominal pain, telangiectasia and/or bronchoconstriction. However, most patients have metastatic disease at diagnosis because the clinic goes unnoticed or are ascribed to other abdominal conditions. We report the clinical symptoms, hormone levels, radiological and nuclear imaging, histological diagnosis, treatment and evaluation of a 44-year-old female patient with congestive heart failure secondary to CARCINOID heart disease in the context of liver metastases of an ileum CARCINOID TUMOR.

CARCINOIDs are the most common neuroendocrine TUMORs, which arise commonly in the gastrointestinal or respiratory tract. Breast CARCINOID is rare and may be primary or metastatic. Primary breast CARCINOIDs account for <1% of primary breast cancer and can be mistaken with other primary breast cancer. Immunohistochemical analysis can be useful in diagnosis. Here we reported a 78 years old women with right breast mass. Mass resected and patient worked up for extra mammary origin. Finally primary breast CARCINOID TUMOR was diagnosed for the patient and modified radical mastectomy and axillary node dissection performed. No adjuvant therapy was used.
