Mucoepidermoid carcinoma occurs more freguently than any other in the major sacivary glands. It is relatively more common in parotid than in submandibular gland. Stewart at al published the first large series of these tumors in 1945 and suggested the name "Mocoepidermoid tumor". Now it is divided three categories : low-grade, intermediate-grade, high-grade. And Mucoepidermoid carcinomas are composed of mucous cells, epidermoid cells, and intermediate cells. We freated low-grade mucoepidermoid carcinoma patient with induction chemotherapy, surpery, and adjuvomt chemotherapy.

Mucoepidermoid carcinoma is one of the most common malignant salivary gland neoplasm. It occurs over a wide age range, and is most common in the parotid gland and usually appears as an asymptomatic swelling. Pain or facial nerve palsy may develop. Minor salivary gland tumors also typically appear as asymptomatic swellings, which are sometimes fluctuant and have blue or red color that can be mistaken clinically for a mucocele. Histopathologically the mucoepidermoid carcinoma is composed of a mixture of mucous-producing cells and squamous (epidermoid) cells. Low-grade tumors show prominent cyst formation, minimal cellular atypia, and relatively high proportion of mucous cells. Mucoepidermoid carcinoma of the minor salivary glands are treated usually by assured surgical excision. For low-grade neoplasm, only a modest margin of surrounding normal tissue may need to be removed, but high-grade or large tumors warrant wider resection. Postoperative radiation therapy also may be used for more aggressive tumors. Mucoepidermoid carcinoma of the oral minor salivary glands generally have a good prognosis, because they are mostly low-to intermediate grade tumors. We present a case of mucoepidermoid carcinoma managed with surgical enucleation and postoperative irradiation and a good clinical result with review of literatures.

The authors analyzed retrospectively the 19 patients with mucoepidermoid carcinoma of salivary glands who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from June, 1986 to September, 1998. The results obtained were as follows: 1. There were 4 males(21%) and 15 females(79%). Age distribution was wide and the mean age was 45.2. 2. Of all mucoepidermoid carcinomas of salivary gonads, 4 cases arose in the major salivary glands and 15 cases in the minor salivary glands. The incidence according to the anatomic primary site for minor salivary glands was 8 cases in the palate, 2 cases each arising in the tongue and floor of mouth and 1 case each arising in the mandible, buccal mucosa and the lower lip. 3. In histopathological classification of mucoepidermoid carcinoma, 5 cases were low grade. 9 cases, intermediate grade and 5 cases, high grade. 4. Perineural invasion was observed 40%(2/5) in high grade and 22%(2/9) in the intermediate grade of mucoepidermoid carcinoma. 5. The incidence of cervical lymph node metastasis according to histopathologic grade was 40% (2/5) in high grade and 11%(1/9) in intermediate grade of mucoepidermoid carcinoma. 6. The lung was the commonest site for metastasis comprising 3 cases among 3 cases of distant spread of which 2 cases in high grade and 1 case in intermediate grade of mucoepidermoid carcinoma.

Mucoepidermoid carcinoma is the most common malignant neoplasm of the salivary gland, compring between 30 and 40%. Fine needle apsiration cytology was performed in five patients with mucoepidermoid carcinoma. The patients consisted of three males aged of 42, 48, and 60 years, and two females aged 36, and 56 years. The primary tumor sites were the parotid gland in four patients and the submandibular gland in the rest one. The histologic grades were low in one patient, intermediate in two patients and high in other two. In our experience, the common cytologic findings of low grade subtype were predominent mucous cells with some intermediate cells in an abundant mucinous background. The cytologic findings of intermediate grade subtype were predominant clusters of intermediate cells with or without mucous cells in an abundant mucinous background. And the cytologic findings of high grade subtype were predominant clusters of epidermoid cells with intermediate cells in a bloody background. Cytologic pleomorphism and atypia were more severe in high grade than low and intermediate grade, and nucleoli were more frequently noted in epidermoid cells. In low grade, it is very difficult to decide the benignancy or malignancy of the tumor. In fact, the presence of mucous cells in a mucinous background should rule out any other type of well differentiated carcinoma.

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.

The purpose of this paper is to review our experience with mucoepidermoid carcinoma(MEC), a rare tumour in minor salivary glands, in a paediatric patients. 15-year-old boy was noted to have a irregular round mass appearing atthe soft palate just to the right of the mid-line. A computed tomographic(CT) scan showed a palatal mass limited to soft palate with no bony erosion. The lesion was curetted and debulked. Pathology was reported as an intermediate-grade mucoepidermoid carcinoma, and the patient was considered to radiation therapy institution for further treatment. To date, patients remain free of disease. Wide local excision is the treatment of choice for low to intermediate grade MEC of the minor salivary glands in paediatric patients.
