Mucoepidermoid carcinoma is one of bronchial adenoma which arising from submucosal gland or mucosal gland of lower respiratory tract. The symptoms of the tumor were produced by bronchial irritation and bronchial obstruction such as coughing, pneumonitis, and atelectasis. The malignancy potency of this tumor was determined by histologic pattern but high grade malignancy was uncommon and so distant metastasis was rare. Three treatment modality such as surgery, radiotherapy, chemotherapy were used for treatment but radiotherapy and chemotherapy were lesser effective than surgery. So Early and radical resection of tumor was recommended. Here we report one case of mucoepidermoid carcinoma which treated with radical resection.

A case of metastatic mucoepidermoid carcinoma of the lung, originating from the hard palate, was diagnosed by sputum and bronchial washing cytology. Although the cytologic features of mucoepidermoid carcinoma have been well described, it is easy to confuse mucoepidermoid carcinoma with the more common primary adenocarcinoma or squamous cell carcinoma of the lung. The features distinguishing mucoepidermoid carcinoma from other primary neoplasms include 1) mucus-secreting cells individually and in clusters admixed with other cell components, 2) epidermoid cells identified by the presence of abundant spread-out cytoplasm and an oval dark nucleus and 3) intermediate cells resembling normal ductal epithelial cells with moderate-to-scanty cytoplasm, a central, round vesicular nucleus and a prominent nucleolus. The morphologic features of metastatic mucoepidermoid carcinoma in this case were similar to those of primary salivary mucoepidermoid carcinoma.

Bronchial mucoepidermoid carcinoma is uncommon, representing 0.2% of all lung tumors. The disease usually presents with symptoms of airway obstruction and recurrent pneumonia. It is commonly classified into two grades in Korea, low and high. We report a case of a bronchial mucoepidermoid carcinoma in a 40-year-old woman who complained of symptoms of an upper respiratory infection. The histological grade after a bronchoscopic biopsy was intermediate. A left upper lobectomy was performed as treatment. The TNM stage of this case was IA (T1N0M0). In addition, 25 cases of bronchial mucoepidermoid carcinoma from 1984 in Korea are also reviewed from the viewpoint of the relationship between the histological grade, TNM stage and clinical course of the tumor.

Mucoepidermoid carcinoma is an uncommon lesion that accounts for approximately 1% of primary malignant bronchial gland tumors and less than 0.2% of all lung neoplasm. This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is uncommon, therefore complete surgical resection is the treatment of choice. The prognosis of tumor correlates with on the histologic grade of tumor. We experienced mucoepidermoid carcinoma in a 15 year-old girl with symptoms of cough and blood tinged sputum. The patient underwent successful removal of tumor by bilobectomy via explorothoracotomy after chest CT and bronchoscopic biopsy.

The mucoepidermoid carcinoma is a rare tumor in the lung. A case of bronchial mucoepidermoid carcinoma diagnosed by fine needle aspiration cytology is presented. The smear showed many intermediate cells with occasional mucus-secreting cells. Malignant squamous cells were not present. The cellular arrangement of intermediate cells was overlapping and grouped in ball-like fashion. These cytologic features are unique for diagnosis of this tumor.

Mucoepidermoid carcinoma was initially recognized as occurring only in the salivary gland and only later was it appreciated that it occurred in the bronchus and trachea as well. Mucoepidermoid carcinoma of bronchial gland origin is extremely rare, and little is known about their natural history. This carcinoma is derived from the minor salivary gland of the proximal tracheobronchial tree and it is divided into low-grade and high-grade by gross, histologic, and ultrastructural criteria. Also its clinical and biologic behaviors are closely related with histologic grade of carcinoma. We have experienced a rare case of bronchial mucoepidermoid carcinoma associated with adenocarinoma which obstructed the left main bronchus and was successfully removed by the pneumonectomy.

The mucoepidermoid carcinoma of the bronchus is very rare neoplasm. The histological appearance is an intimate mixture of mucous-producing cell and epidermoid cell. The malignant potency of the tumor was determined by histologic pattern. Bronchoplasty techniques represent the ideal form of excisional therapy for benign endobronchial tumor as well as tumors of low-grade malignant potential, such as bronchial adenoma, and for repair of traumatic airway injuries and benign stricture and selected group of patients with carcinoma of the lung. We experienced a case of-low-grade mucoepidermoid carcinoma in a patient of 21-year old male who has been suffered from hemoptysis episodes for several years. The sleeve resection of left main bronchus and left lower lobectomy due to bronchiectatic change were carried out. The patient are being followed up without specific problem.

Bronchial adenomas are a group of rare tumors representing less than 1% of primary lung neoplasms. Mucoepidermoid carcinoma of the lung is a very rare subtype of bronchial adenoma. We experienced a case of 20 year old patient with mucoepidermoid carcinoma of the lung, so we present this case of mucoepidermoid carcinoma with literature review.

The mucoepidermoid carcinoma is a rare tumor in the lung for less than 1% of all pulmonary neoplasm. It is mostly presented as a solitary pulmonary nodule at a large bronchial tree on bronchoscope. But more peripheral located tumor that not accessible to the bronchoscope are rarely reported on literature. The cytologic findings of these tumors are discribed as a mixture of squamous cells, mucous cells, and intermediate cells with overlapped cellular clusters. We experienced a case of peripheral mucoepidermoid carcinoma of lung diagnosed by fine needle aspiration cytology. The smear showed many cellular clusters on mucoid background. They consisted of many intermediate cells with occasional mucus-secreting cells, but malignant squamous cells were not present.

Mucoepidermoid carcinoma developed in tracheobronchial tree is one of rare lung tumor. It is histologically divided into low grade malignancy of relatively benign course versus high grade malignancy of fatal course. In low grade malignancy, it can be curative with a surgical resection. We experienced a case of mucoepidermoid carcinoma in a 28-year-old woman who complained sudden dyspnea and presented right total lung collapse on chest roentgenogram. It was diagnosed as a low grade mucoepidermoid carcinoma and removed by the surgical excision.
