  • Mucoepidermoid tumor arising from the bronchial tree as one of the bronchial adenoma is a extremely rare in incidence. And its clinical and histopathologic behavior has been reported as varying degree of benign to extremely malignant. Because symptoms are usually related to the bronchial obstruction or obstructive pneumonitis followed by endobronchial growth of tumor, frequently error is made in diagnosis of this tumor as entity of obstructive lung disease. We present a case of mucoepidermoid tumor with review of relevant literatures arising from the right middle lobe bronchus extending to intermediate bronchus in 47 years old housewife and was surgically removed by middle and lower Iobectomy.

  • Mucoepidermoid cancer of the bronchus in childhood is extremely rare. These tumors generally produce symptoms of airway obstruction, often misdiagnosed as unresolved tuberculosis. Distant metastasis is an uncommon finding of this malignancy, therefore complete surgical resection is treatment of choice. The prognosis of these tumors correlates with the histologic grade of the tumor. We report our clinical experience of mucoepideromoid cancer in a 10-year-old child who visited our hospital with symptoms of recurrent cough and fever. The patients underwent successful removal of tumor by bilobectomy via thoracotomy after bronchoscopic biopsy.

  • Authors experienced a case of intermediate grade mucoepidermoid carcinoma in 29-year-old female. The origin of this tumor might be mucus secreting cells of palatal mucous gland. The characteristic features were as follows: 1. In clinical examination, exopytic mass was observed in left hard palate and similar to pleomorphic adenoma. 2. In radiographic findings, destructive changes of left hard palate, nasal septum, nasal inferior turbinate and floor of maxillary sinus and soft tissue mass were observed. 3. Histopathologically, mucus-secreting cells, epidermoid cells and intermediate cells were observed and diagnosed as intermediate grade mucoepidermoid carcinoma.

  • Mucoepidermid tumors are usually indistinquishable from benign tumors clinically, and accounts for approximately 6% to 8% of all salivary gland tumors. Although rare in children, it is the most common "malignant" salivary gland tumor, haying been reported in major and minor (intraoral) salivary gland sites as well as in the maxilla and the mandible. In children, as in adults, it most often occurs in the parotid gland, but a significant percentage is found in the palate. Presently, there is no unanimity of opinion about whether to consider all mucoepidermoid tumors malignant or what the most appropriate treatment regimen is. The importance of submitting, for microscopic diagnosis, all tissue removed during surgical procedure is illustrated in this case report and a review of the literature is presented.

  • Mucoepidermoid carcinoma of the lung is extremely rare. This rare tumor arise beyond the carina, usually main stem bronchi, but occasionally in lobar or segmental airways, This tumor presents with symptoms of bronchial irritation or obstruction. Distant metastasis is an uncommon, therefore complete surgical resection is the treatment of the choice. The prognosis of this tumor correlates with the histologic grade of the tumor. We experienced a case of mucoepidermoid carcinoma arising from the right middle lobe, which was treated with the right middle lobectomy, with good result. We report this case and follow-up of the patient.

  • 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.

  • Salivary gland tumors take possession of almost 5% in head and neck malignancies. Among these, mucoepidermoid carcinoma(MEC) is most common malignany in major salivary glands(12-29%) and the parotid gland is most predilection site. Intra-oral MEC has a tendency to various locations, and the predilection sites are palate, cheek, mandible, lip and tongue in order of frequency. A few cases of MEC are occurred in with retromolar trigone, oropharynx, and ectopic salivary gland. Recently, we experienced a-65-year old woman with retromolar trigonal mass, and she was finally diagnosed as MEC. We report it with review of literature.

  • 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.

  • Mucoepidermoid carcinoma of the lung can be divided into low grade and high grade varieties, like their major salivary glands counterparts. This carcinoma comprises only. about 0.5% of all pulmonary neoplasma. Their clinical and biologic behaviors are closely related with histologic grade of carcinoma. We have experienced two cases of mucoepidermoid carcinoma. Case 1 occurred in a 16 years old male and showed the histologic features of low grade type. This carcinoma arised from the right upper lobe bronchus which was removed by the right upper lobectomy. Case 2 occurred in a 41 year old male was the high grade carcinoma located at the distal left main bronchus which was removed by the left pnemonectomy.

  • The segmental mandibulectomy should be performed, if mandiblie invasion is suspected clinically and radiologically. And if tumor is located to mandible very closely or when microinvasion to mandible is suspected, marginal mandibulectomy is recommended. But in segmental mandibulectomy, reconstruction is difficult and cosmetic problem remains. In this case, we performed modified segmental resection of mandible, preserving the inferior margin of mandible, and maintains the continuity of the bone, in mucoepidermoid carcinoma of parapharynx, invading mandible. We reviewed the diagnosis, pathology, and treatment, and report the case with reviews of literature.
