Carcinoid tumours are uncommon well-differentiated neuroendocrine tumours. Primary duodenal carcinoids account for less than 2% of all gastrointestinal carcinoids. Duodenal carcinoids are seldom associated with carcinoid syndrome. We report a rare case of duodenal carcinoid presenting as a carcinoid syndrome in a middle-aged man with upper abdominal pain, hot flushes, diarrhoea and dry cough. Endoscopy-guided biopsy and 24 h urine 5-hydroxyindoleacetic acid (5-HIAA) proved the diagnosis. He was further evaluated and managed with definitive surgical treatment.

Thymic carcinoid tumour associated with pulmonary squamous cell carcinoma is very rare. We present a case of synchronous lung cancer and mediastinal tumour treated with simultaneous video-assisted thoracoscopic surgery (VATS) sleeve lobectomy and thymectomy. A 67-year old man presented with cough and bloody sputum. Chest computed tomography showed an anterior mediastinal mass with a right hilar nodule. A right upper sleeve lobectomy and a thymectomy were performed via a VATS approach. Thymic carcinoid tumour associated with pulmonary squamous cell carcinoma was diagnosed, and the patient received adjuvant radiochemotherapy.

The pulmonary neuroendocrine neoplasms originate from the enterochromaffin cells which are diffusely distributed in the body. The incidence of these tumors has increased significantly in recent decades due to the available diagnostics. They make up about 1-2% of all lung tumors and 20-30% of all neuroendocrine neoplasms. The current WHO classification from 2004 divides them into typical carcinoids (TC), atypical carcinoids (AC), large cell neuroendocrine carcinomas (LCNEC) and small cell carcinomas (SCLC). The major neuroendocrine biomarkers are chromogranin A, synaptophysin and CD56. TC have a low mitotic rate of <2 mitoses/2mm(2) (10 HPF), whereas the mitotic rate of the AC is 2-10 mitoses/2 mm(2) (10 HPF). The Ki-67 staining is helpful to distinguish typical and atypical carcinoids from the highly malignant LCNEC and SCLC. Clinically, the patient presents usually with cough, hemoptysis or bronchial obstruction. The occurrence of a carcinoid or Cushing's syndrome and a tumor-associated acromegaly are rare. Surgical resection with radical lymph node dissection is the treatment of choice for achieving long-term survival. Endoscopic resection of the endobronchial tumor growth is a good alternative for inoperable endobronchially localized tumors. Peptide receptor radionuclide therapy (PRRT) is a promising treatment option for patients with metastatic or unresectable pulmonary neuroendocrine tumors. New targeted therapies using angiogenesis inhibitors, mTOR inhibitors, and tyrosine kinase inhibitors are being tested for their effectiveness in many previous studies. Typical carcinoid tumors metastasize less frequently than AC, the 5-year survival rate of patients with TC being over 90%. Patients with AC have a 5-year survival rate between 35% and 87%. The highly malignant LCNEC and SCLC, on the other hand, have a 5-year survival rate between 15% and 57%, and <5% respectively. The increasing number of therapeutic options and diagnostic procedures requires a multidisciplinary approach and decision-making in multidisciplinary tumor conferences to ensure a personalized treatment approach. Therefore patients with a neuroendocrine neoplasm of the lung should be treated in specialized centers.

Bilateral multiple typical carcinoid tumors of the lung are uncommon malignancies. We discuss the case of a 64 year-old female with a nonproductive cough as the initial symptom. Thoracic computed tomography revealed multiple nodular lesions on both sides, which were initially misdiagnosed as multiple metastases of the lung with an unknown primary. After resection of nodules in the right hemithorax, pathologic examination revealed a typical carcinoid tumor. Bilateral sequential thoracotomy was performed and all ten nodules, (six on the right side and four on the left side), were treated by sublobar resection due to poor respiratory function. Pathological examination revealed all nodules to be typical carcinoid tumors. Following the resections, the patient has remained disease-free for ten months.

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare cause of obstructive lung disease and a proposed precursor of pulmonary carcinoid tumors. With increased awareness of this disease, an accumulating number of cases have been reported. Patients may have progressive shortness of breath due to small airway obstruction. There is limited information on treatment of the disease, particularly for those with progressive disease. Here we report 2 patients who were treated at our institution with double lung transplantation. Both patients were female nonsmokers with a clinical presentation of cough and dyspnea. Multiple bilateral lung nodules were identified on high-resolution computed tomography and pulmonary function tests showed obstructive pattern in both patients. The diagnoses of DIPNECH were made by histologic evaluation of the explanted native lungs. These 2 patients are in stable condition following double lung transplantation at the time of this report. DIPNECH is increasingly recognized due to improved sensitivity of investigative imaging and increased awareness of the entity. Considering the malignant potential and lack of effective treatment of the disease, lung transplantation could be potentially an effective treatment option for these patients.

Carcinoid is one of the most common tumors of the gastrointestinal tract followed by the tracheobronchial tree. Bronchial carcinoid compromises 20% of total carcinoid and accounts for 1-5% of pulmonary malignancies. Carcinoid can be typical or atypical, with atypical carcinoid compromises 10% of the carcinoid tumors. Carcinoid usually presents as peripheral lung lesion or solitary endobronchial abnormality. Rarely it can present as multiple endobronchial lesion. We hereby present a rare case of an elderly gentleman who had undergone resection of right middle and lower lobe of lung for atypical carcinoid. Seven years later he presented with cough. CT scan of chest revealed right hilar mass. Flexible bronchoscopy revealed numerous endobronchial polypoid lesions in the tracheobronchial tree. Recurrent atypical carcinoid was then confirmed on biopsy.

Wet cough, wheeze, and sputum in an adolescent with evidence for bronchiectasis is an uncommon presentation. The differential diagnosis includes cystic fibrosis (CF), immunodeficiency disorders, complement deficiency, allergic bronchopulmonary aspergillosis, alpha-1 antitrypsin disease, repeated aspiration pneumonia, foreign body, bronchial carcinoid, unresolved right middle lobe pneumonia, and primary ciliary dyskinesia (PCD). The likely diagnosis proceeds from the more to less common in patients with these symptoms. The location of disease on computed tomography scanning, nasal and bronchial exhaled nitric oxide, identification of ultrastructural defects on electron microscopy, and specific genetic mutation help separate CF and PCD. Although differentiating these conditions is vital, the chronic management of the bronchiectasis usually includes clearance mechanisms, bronchodilators, regular exercise, appropriate vaccinations, and judicious antibiotics for airway infections.

Bronchial carcinoid tumors (BCTs) are an uncommon group of lung tumors. They commonly affect the young adults and the middle aged, the same age group affected by other more common chronic lung conditions such as pulmonary tuberculosis. Diagnosis is commonly missed or delayed due to a low index of suspicion. Surgery is the mainstay of treatment with an excellent outcome. There are many reports of this rare group of tumors in the Western and Asian regions. The only report around our sub-region is a post mortem report of an atypical variant. We wish to report a case of the typical variant and increase our index of suspicion. A 25-year-old male presented with a 4 years history of cough and haemoptysis. He was repeatedly treated for bronchial asthma and pulmonary tuberculosis with no improvement of symptoms. Chest X-ray and chest computed tomography scan revealed a left upper lobe tumor. Histology reported a typical variant of BCT which was confirmed by immunohistochemistry. He had a left upper lobectomy and has done excellently well thereafter. A high index of suspicion is needed to reduce the risk of missing or delaying the diagnosis.

Carcinoid tumours arise from the neuroendocrine cells of the bronchial epithelium known as Kulchitsky cells and comprise 4% of all lung malignancies. We report a case of a 16- year-old male who presented with a 1-month history of fever, cough, left-side chest pain and shortness of breath. Chest X -ray showed loss of lung volume on the left side with cystic spaces and air fluid levels. Computed tomography scan chest demonstrated a homogenous mass extending into the left main bronchus causing its complete obstruction along with extensive bronchiectatic changes in the left lung. Bronchoscopy and bronchial biopsy confirmed the diagnosis of typical carcinoid tumour. A pneumonectomy was performed. This case is unusual due to the large size of the tumour, its location and associated destruction of the entire left lung.

To investigate the initial symptoms, treatment, prognosis, and 1-, 3-, and 5-year survival of patients with bronchopulmonary carcinoid, clinical and pathological data were collected retrospectively from 74 patients diagnosed with bronchopulmonary neuroendocrine tumors at the Cancer Hospital, Chinese Academy of Medical Science, from January 2004 through December 2009. The data collected included age, initial symptoms, primary tumor sites, pathological types, lymphatic metastasis, and distant metastasis. The Kaplan-Meier method was used for survival analysis and the log-rank test was used for univariate analysis of prognostic factors. A Cox proportional hazard regression model was used for multivariate analysis. The 74 patients included 56 men and 19 women, and their average age was 56.07 years. The most common initial symptom was cough (51.35%), and the major lesion site was the left upper lobe of the lung (38.84%). Of the 59 patients (79.73%) who underwent surgery, most (76.27%) received a pulmonary lobectomy. The patients' 1-, 3-, and 5-year survival rates were 92.7, 80.3, and 71.9%, respectively. Univariate analysis showed that both local lymphatic and distant metastases were prognostic factors (P<0.05), whereas multivariate analysis showed that the pathological type (typical carcinoid and atypical carcinoid) was an independent prognostic factor (P=0.006). These data indicate that cough is the major presenting symptom of patients with bronchopulmonary carcinoid and the left upper lobe of the lung is the most commonly involved site. Following treatment, mostly by pulmonary lobectomy, the 5-year survival rate is 71.9%. The pathological tumor type is an independent prognostic factor.
