The major categories of neuroendocrine tumors of lung are typical carcinoid, atypical carcinoid, large cell neuroendocrine carcinoma, and small cell carcinoma. The histologic classification criteria of neuroendocrine tumors are well documented in the "WHO Classification of Tumors" based on mitotic figures and necrosis. Cytologic characteristics of neuroendocrine tumors are trabecular, acinar, and solid arrangement of tumor cells and occasional rosette formation. Nuclear chromatin patterns are characteristically described as "salt and pepper chromatin pattern". Many of cytologic classifications documented in the literature are before the "WHO Classification". In this review, the cytologic features of pulmonary neuroendocrine tumors are documented according to the WHO classification, and recent concepts of neuroendocrine tumors of lung are discussed.

Carcinoid tumors of the thymus are vanishingly rare, and the characteristic cytologic findings of this condition have never before been reported in Korea. Recently, we encountered a 58-year-old woman who had been suffering from general weakness and weight loss for several months. Radiological imaging revealed a large anterior mediastinal mass. A fine needle aspiration biopsy (FNAB) of the mass showed predominantly scattered single cells, as well as some loose clusters of small cells with scanty cytoplasm. Some of these small cells exhibited plasmacytoid features, with moderately granular cytoplasm. We also discuss the cytological differential diagnosis between thymic carcinoid and other mediastinal tumors.

This study aims to report a case of rectosigmoid neuroendocrine tumor patient with liver metastasis whose outstanding carcinoid symptom was mucosal diarrhea for more than 10 times a day. Three different herbal decoctions were administered orally for the treatment of diarrhea which was among carcinoid symptoms from diffuse metastatic liver lesion. The herbal decoctions given were modified Lijung-tang, modified Sambaek-tang and modified Jeokseokjiuyeoryang-tang. The administration period was 5, 14 and 9 days respectively. Frequency of patient's mucosal diarrhea had increased consistently during hospitalization. It had almost doubled compared to pre-hospitalization up to 27 times/24 hrs. But during the period of modified Sambaek-tang administration, frequency of diarrhea was maintained between 9 to 15 times/24hrs. There was no difference of liver tumors between Nov 16th 2013 and Dec 9th 2013 in computed tomography images. Three conventional established herbal prescriptions administered in this case didn't show any favorable effect on improving mucosal diarrhea induced by carcinoid symptoms of a rectosigmoid neuroendocrine tumor with liver metastasis. Even if modified Sambaek-tang showed partial effect on frequency of diarrhea, we concluded that it was not sufficient to be a therapeutic method of the diarrhea as carcinoid symptom. Furthermore, it is necessary to conduct additional studies about the diarrhea of neuroendocrine tumor with liver metastasis.

Bronchial carcinoid tumor accounts for less than 5% of all primary lung tumors in adults. Although surgical resection is the treatment of choice, here we report a case of bronchial carcinoid tumor treated with flexible bronchoscopic resection. A 19-year-old-man presented with a history of wheezing with dyspnea for six months. A simple chest x-ray showed no abnormal findings, but a pulmonary function test showed a moderate obstructive lung disease pattern without a bronchodilator response. A computed tomogram of the thorax revealed an enhanced $15{\times}12$ mm nodule in the left main bronchus. Bronchoscopic examination showed a polypoid mass with a stalk in the left main bronchus, which almost completely occluded the left main bronchus. Histopathology of the resected specimen revealed a bronchial carcinoid tumor. We treated the carcinoid tumor with a flexible bronchoscopic resection. During the follow up period of 6 months, the previous tumor didn't relapse. Initial bronchoscopic resection should be considered when bronchial carcinoid tumor can be approached by bronchoscopy.

Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management. We report a case of atypical carcinoid with local recurrence and pleural metastases treated by video-assisted thoracoscopic surgery lobectomy and total pleurectomy with photodynamic therapy after non-radical wedge resection.

Carcinoid tumors arising in the thymus are rare. Since Rosai and Higa in 1972 distinguished these neoplasms from thymomas, fewer than 100 cases have been reported in the world literature. The pathologic diagnosis of thymic carcinoids is been on findings from light microscopy, histochemical studies, and electron microscopy. About 50% of thymic carcinoids are seen with endocrinopathies. Recurrence and extrathoracic metastasis are characteristic of thymic carcinoids. Surgical extirpation of the tumor initially and of the subseguent recurrences in the most effective treatment today The role of adjuvant radiotherapy and chemotherapy is still uncertain. Herein we report a case of thymic carcinoid tumor in a 36-year old male with brief review of literatures.

Tumors that metastasize to the pituitary gland are unusual and metastasis of neuroendocrine neoplasm to the sellar region is extremely rare. We report a 59-year-old man with pituitary metastasis from pulmonary carcinoid tumor who presented with left progressive deterioration of visual field. Sellar dynamic magnetic resonance imaging revealed an enhancing sellar mass invading the left cavernous sinus. We report this unusual case with a review of the relevant literature.

Bronchial carcinoid tumors are relatively uncommon neoplasms that are considered to be malignant tumors of low to intermediate grade. They are classified by pathologic features as typical or atypical carcinoids and have distinctly different prognoses and therapeutic options. Surgery is the treatment of choice in typical and atypical carcinoid tumors but the approach has been changing. Recently, several studies have described experiences using other technologies as adjuncts to bronchoscopic resection, technologies such as laser and cryotherapy with curative intent in endoluminal typical carcinoids. Here we present a case of atypical bronchial carcinoid that was treated with bronchoscopic cryotherapy.
