17 cases with bronchial carcinoid were reported. 16 cases of them were proved pathologically after pulmonary resection, and the remaining one was confirmed histopathologically through bronchoscopic biopsy. 64.7% was under 40 years of age. The main clinical manifestations were cough, hemoptysis, fever and repeated pneumonitis. In one patient, the carcinoid was associated with Cushing's syndrome. Chest roentgenograms showed lesions centrally located in 12 cases, and peripherally located in 5 cases. Histological examination revealed 15 typical and 2 atypical carcinoid tumors. This disease was usually misdiagnosed as lung cancer, tuberculoma and benign tumors. Chest X-ray examination and fiberoptic bronchoscopic biopsy are helpful to the diagnosis of the disease. Pulmonary resection was performed in 16 cases. Two patients had hilar lymph node metastases, one of them had also involvement of pericardium. There was no operative mortality. In the follow-up study, the disease-free actuarial survival following pulmonary resection was 92.9% at 5 years. 2 patients died. One died of respiratory failure 4 months after pneumonectomy, the other died of pericardium involvement of carcinoid 8 months after operation. Resection is the only effective treatment for bronchial carcinoid.

Bronchial carcinoid tumors (BCT) are the most frequent primary pulmonary neoplasms of childhood. Seventeen of 208 patients diagnosed as having BCT at the Massachusetts General Hospital were between 10 and 21 years of age. We reviewed our records of the 17 patients and 8 other pediatric cases and compared their findings with those of seven large series of adults. Distribution was equal between the sexes. The average age at diagnosis was 17 years; 4 patients were < or = 15 years old. The duration of symptoms prior to diagnosis varied from 2 weeks to 2.6 years, with a median duration of 8.5 months. In contrast to adults, no child was asymptomatic. The majority of children presented with wheezing and atelectasis in addition to the characteristic adult triad of cough, hemoptysis, and pneumonitis. Five patients presented with weight loss and one patient presented with hoarseness. One of the 17 pediatric patients presented with Cushing's syndrome and a functional BCT. Twelve of 14 patients were disease free for 9 months to 34 years after surgical resection. We conclude that BCT should be suspected in children with pneumonitis resistant to therapy, atelectasis, wheezing, and hemoptysis. Surgical resection will result in symptom-free recovery in the majority of cases in spite of low-grade malignancy.

Pulmonary carcinoid tumors are neuroendocrine malignant tumors that make up 1% to 2% of all lung tumors. According to histopathologic criteria, carcinoids can be divided into typical (TC) and atypical (AC) carcinoids. Carcinoids can be placed in a spectrum of neuroendocrine tumors, ranging from low-grade malignant TC to intermediate AC to high-grade large-cell neuroendocrine carcinoma and small-cell lung carcinoma. Familial pulmonary carcinoids are rare. The most common symptoms are hemoptysis, cough, recurrent pulmonary infection, fever, chest discomfort and chest pain, unilateral wheezing, and shortness of breath. Paraneoplastic syndromes are rare and include carcinoid syndrome, Cushing's syndrome, and ectopic growth hormone-releasing hormone secretion. The diagnosis is usually established by flexible bronchoscopy and biopsy, although occasionally this can result in severe hemorrhage. Immunoscintigraphy by somatostatin analogs can also be useful in diagnosis. The treatment of choice is surgical resection, and prognosis is relatively good in TC, although it is worse in AC. The role of radiotherapy and chemotherapy as part of multimodality treatment or palliation is still debated.

A case of pulmonary tumorlets with ectopic adrenocorticotropin (ACTH) production and lymph node metastasis in a bronchiectatic patient is reported. A 65-year-old man underwent right lower lobe lobectomy because of a sudden attack of cough and hemoptysis. Histological study revealed multiple discrete uniform small nests of tumor cells surrounding dilated bronchioles. Tumor nests were also found in the hilar lymph node. Immunohistochemically, the proliferating cells were confirmed to be neuroendocrine in origin with ectopic ACTH production, despite being clinically silent. The findings in the present case suggest that the clinical behavior of pulmonary tumorlets may be like a carcinoid, and need to be treated as tumor-like lesions. Ectopic hormonal production in the present case suggests pulmonary tumorlets should be considered in the differential diagnosis of Cushing's syndrome.

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.
