Forty cases of carcinoid tumors of the lung were studied retrospectively from 1989-1993 in the Pathology Department of Hospital Pulido Valente in Lisbon. The mean age of patients was 44 years old, and the presenting symptoms included hemoptysis, cough, thoracic pain, fever, and dyspnea. An endobronchial mass was seen in 75% of the cases. The histopathological study was based on the following morphological criteria: disorganized architecture with increased cellularity (8 cases; 20%), nuclear pleomorphism (14 cases; 22%), the presence of coarse chromatin (19 cases; 30%), increased mitotic activity (13 cases; 21%), enlarged nucleoli (17 cases; 27%), necrosis (12 cases; 25%), vascular permeation (8 cases; 15%), distant metastasis (6 cases; 14%). Chromogranin was the most strongly reliable immunostaining for the diagnosis. In our series the initial routine diagnosis and the diagnosis after morphological criteria evaluation matched, and in 14 cases the final diagnosis was of atypical carcinoids.

Clinical presentation, pathology, surgical management and follow-up of ten bronchial carcinoid tumour (BCT) patients are described. There were five male and five female patients with age range between 5 to 85 years (mean 39.2 +/- 21.5, SD). Pathology revealed BCT on the right side in seven and on left side in three patients. The tumour was an incidental finding in four while the other six had respiratory symptoms. Cough was present in all of the later group and hemoptysis was present in four patients. Recurrent chest infections were seen in two patients. Symptoms ranged from 1 week to 15 years. Successful surgical resection was done in nine with the longest follow-up of 80 months (mean: 23 months +/- 26.3, SD) without recurrence or metastasis. Histopathological examination of these tumours revealed classical morphological features in all but one case. Grimelius stain positivity for argyrophilia confirmed the diagnosis in all the patients in this study. Electron microscopic examination was done in patient no. 9 which showed atypical morphological features and neurosecretory granules. BCT may present like pneumonias or bronchial asthma. Although BCTs have low-grade malignancy, early diagnosis and surgical resection yield curative results almost in all cases.

Forty-two fine-needle aspirates (FNA) of the mediastinum were reviewed from 1984-1995. The clinical, radiologic, pathologic, and cytologic material was studied. Twenty-five males and 17 females had an age range from 10-72 yr and a mean of 41 yr. Common complaints were chest pain, dyspnea, and cough. Thirty-eight tumors were in the anterior/superior mediastinum. Fifty-seven percent were primary neoplasms (Hodgkin's lymphoma, 7; non-Hodgkin's lymphoma, 6; thymoma, 3; germ-cell tumor, 3; thymic carcinoid and angiosarcoma, 1 each; and malignant not otherwise specified, 3). Twenty-four percent were metastatic tumors (carcinoma, 9; and sarcoma, 1). Twelve percent were benign conditions (granulomatous disease, 2; multinodular goiter, 1; extramedullary hematopoesis, 1; and one thymic cyst). Seven percent were inconclusive. FNA yielded adequate tissue for diagnosis in 83% and a correct diagnosis in 86%. There was one false-negative and no false-positive diagnosis. FNA is a useful tool for accurate tissue diagnosis of mediastinal masses.

Typical pulmonary carcinoid tumors often present as proximal endobronchial masses discovered during the evaluation of cough and/or hemoptysis. We present a case of a carcinoid tumor that presented with spontaneous partial expectoration. A review of the literature revealed 16 cases of expectoration of fragments from various primary and metastatic tumors. Our case appears to be the first report of the expectoration of a carcinoid tumor.

Carcinoids are neuroendocrine neoplasms. Bronchial carcinoids are unusual, malignant primary neoplasms that characteristically involve the central airways and typically exhibit well-defined margins and bronchial-related growth. Bronchial carcinoids include low-grade typical carcinoids and the more aggressive atypical carcinoids. These tumors usually affect patients in the 3rd through 7th decades of life who are often symptomatic with cough, hemoptysis, or obstructive pneumonia. Bronchial carcinoids radiologically manifest as hilar or perihilar masses, with or without associated atelectasis, pneumonia, bronchiectasis, or mucoid impaction. At computed tomography, an anatomic relationship of these tumors to a bronchus is usually seen, and they may show contrast material enhancement or calcification. In rare cases, carcinoids occur in the thymus; when they do, they are aggressive tumors that affect adults who usually present with chest pain, cough, and dyspnea. Thymic carcinoids manifest radiologically as anterior mediastinal masses and may mimic thymomas. Thoracic carcinoids are treated by surgical excision. The prognosis for patients with typical bronchial carcinoids is excellent; patients with atypical bronchial or thymic carcinoids have a worse prognosis.

The carcinoid tumors of the bronchial are extremely uncommon, with an incidence of 5% of all pulmonary neoplasms. The carcinoid is the more frequent tumor of the lung in paediatric age. The symptoms most often reported were cough, recurring infection, chest pain, hemoptysis, fever, dyspnea, mild dyspnea attacks after physical effort or nervousness. The carcinoid syndrome is uncommon. Neuroendocrine tumors of the lung embrace a spectrum from low-grade typical carcinoid, intermediate-grade atypical carcinoid, and high-grade categories of large cell neuroendocrine carcinoma and small cell carcinoma. Low grade neoplasms may metastasize to adjacent nodes. Atypical carcinoids are considered low grade malignancies. Most malignant end of neuroendocrine neoplasm group is small cell carcinoma. Typical carcinoids carry an excellent prognosis and should be offered conservative lung resection, whilst atypical carcinoids which behave aggressively should be treated by radical lung resection. The authors report a case of the young patients with bronchial typical carcinoid tumor who had suffered from cough and mild dyspnea attacks after physical effort or nervousness in the last year.

We describe two cases of atypical carcinoid of the thymus. One was an 82-year-old woman with complaints of nonproductive cough and back pain, and the other a 64-year-old woman with no symptoms. Computed tomography scans of the chest in both cases revealed a large mass in the anterior mediastinum. Multiple metastases to bone and liver were also noted in the former case. Histological examination of their tumors revealed that the tumor cells were arranged in a nested, trabecular, or pseudorosette pattern, with increased numbers of mitoses, nuclear pleomorphism, and presence of necrosis. In addition, immunohistochemically, the cells stained for neuron-specific enolase, synaptophysin and chromogranin A. Combination chemotherapy consisting of carboplatin and etoposide was performed as initial chemotherapy in the former case and as adjuvant therapy in the latter. The former patient achieved a short-term partial response. It is important to differentiate atypical carcinoid from other thymic tumors, since such tumors including thymoma have a much better prognosis than does atypical carcinoid.

A case of a 7-year-old boy admitted to the clinic with severe symptoms of 1-month lasting pneumonia not responding to antibiotics is presented. The chest X-ray confirmed inflammatory process in left lung parenchyma. Due to unsuccessful further preservative treatment, bronchoscopy and CT of the thorax were performed. They showed the presence of a tumor narrowing the left main bronchus. Histopathologic examination of the tissue taken during bronchoscopy revealed carcinoid. Through the left-sided thoracotomy, the resection of a 5 cm large oval-shaped tumor, as well as the distal part of the left main bronchus was done. During clinical observation the child did not present any symptoms of the carcinoid syndrome. Urine levels of acids: homovanillic, vanillylmandelic and 5-hydroxyindolylacetic were normal. Bronchoscopy and X-ray of the chest directly, two weeks after and six months after resection were normal. Childhood primary pulmonary neoplasms are rare and the most frequent malignant tumors are bronchial adenomas. About 80-90% of them are carcinoids. The period from initial symptoms to clinical diagnosis and the institution of treatment, usually lasts several months. In our case it was a seven-week-long period. When cough, weezing, hemoptysis and inflammation of lung parenchyma are prolonged, carcinoid should always be considered in differential diagnosis. Radiological changes are usually nonspecific in cases of bronchial adenomas. Bronchoscopy with biopsy and CT scan are investigations that are decisive. Because of relatively low malignancy of carcinoid, results of the surgical treatment are good even in presence of metastases in regional lymphatic nodules.

Carcinoids are neuroendocrine neoplasms. Bronchial carcinoids are unusual, malignant primary neoplasms that characteristically involve the central airways and typically exhibit well-defined margins and bronchial-related growth. Bronchial carcinoids include low-grade typical carcinoids and the more aggressive atypical ones. They usually affect patients in the 3rd through the 7th decade of life who are often symptomatic with cough, hemoptysis or obstructive pneumonia. Rarely, the initial symptoms are related to the secretion of hormones causing carcinoid or other endocrine syndromes. Bronchial carcinoids radiologically manifest as hilar or perihilar masses, with or without associated atelectasis, pneumonia or bronchiectasis. At CT-scan the relationship of these tumors with the bronchial tree is usually seen, and they show contrast enhancement or calcification. Even if the radiological signs may be suggestive for bronchial carcinoid, the definitive diagnosis is reached only by the tissue sampling. Bronchoscopic biopsy is the more effective way to identify the nature of carcinoid tumors because of their frequent central location. The treatment of choice is the surgical resection which should be carried out with maximum respect for the residual lung and bronchial tissues. Endoscopic ablations in well defined cases, bronchotomy and lung resections with or without bronchoplastic procedures have been described. Hilar and mediastinal lymph node sampling and examination should be ever performed during open procedures. Positivity of the nodal tissues could influence the resection procedure and is related with the prognosis, specially for the atypical carcinoids. Chemo- and radiation therapy are not effective in improving the long-term outcome in those patients with advanced disease. The long-term outcome is strictly related with the histological subtype and the lymph node status. Local recurrences and distant metastases are more frequent in the atypical carcinoids which manifest a more aggressive behavior. During the last decade, the importance of the use of somatostatine analogues (octreotide) in the staging, early detection of the recurrent disease and its management such as that of the associated carcinoid syndrome became clear.

Pulmonary glomus tumours are rare lesions, with few cases reported previously. Herein, we present the clinical and pathological features of a case of pulmonary glomus tumour. A 29-year-old female patient presented to our clinic complaining of cough, dyspnoea and left-sided chest pain. Computed tomography (CT) of the thorax revealed a nodular lesion causing obstruction of the left main bronchus. Fibreoptic bronchoscopy demonstrated a polypoid mass occluding the left main bronchus 10 mm distal to the main carina. Bronchoscopic biopsy was interpreted histologically as carcinoid tumour. Bronchotomy plus mass extirpation was performed with left thoracotomy. Microscopically, a tumoral structure composed of uniform cells with a round centrally located nucleolus and narrow eosinophilic cytoplasm was seen. Thin-walled vessels lined with endothelium were interspersed between tumoral structures. The cells were stained chromogranin and cytokeratin negative and strongly vimentin positive. The pathological diagnosis for the thoracotomy specimen was pulmonary glomus tumour. Follow-up chest CT was negative for recurrent tumour and the patient remains free of disease 17 months after surgery.
