  • 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.

  • Mucoepidermoid carcinoma is one of the most common malignant tumors that occur in the salivary glands. While several cases of distant metastasis have been reported, instances of metastasis to the skin are rare. We present the case of a 72-year-old man diagnosed with parotid mucoepidermoid carcinoma who experienced temporary remission following surgical resection and adjuvant chemoradiotherapy. However, the carcinoma recurred along the skin at the periauricular area along the mask line. Given the current prevalence of COVID-19, the practice of wearing masks has become more widespread. This case report highlights the recurrence of mucoepidermoid carcinoma along the mask strap line, emphasizing the importance of distinguishing it from benign dermatological conditions.

  • The mucoepidermoid cancer is a tumor arising in the bronchial submucosal glands that shows an intimate admixture of glandular element and sheets of cell with or no definite squamous differentiation. This rare tumor is usually located in lobe and bronchi and occasionally in the trachea. This tumor presents with symptoms of bronchial irritation or obstruction, often of several years duration. The treatment is complete resection with use of bronchoplastic techniques.Low grade tumor have a good prognosis with adequate resection. We experienced a case of mucoepidermoid cancer arising from superior segment of left lower lobe, which was treated with Lt.lower lobectomy.

  • 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 carcinomas (MECs) arising within the jaws as primary central bony lesions are termed central MECs. Central MECs are extremely rare, comprising 2-3% of all mucoepidermoid carcinomas. We herein report a rare case of central MEC of the maxilla in a 52-year-old male whose plain radiographs showed a "ground glass" pattern and computed tomographic images, a hypodense mass with numerous calcifications. To the best of our knowledge, this is the first report of central MEC showing a "ground glass" appearance.

  • 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.

  • Mucoepidermoid carcinoma of the lung is a very rare and potentially malignant tumor that arises from submucosal gland of the trachea and bronchi. We experienced two cases of mucoepidermoid carcinoma which was located in the left main bronchus and right intermediate bronchus. They were treated with left sleeve resection and right bilobectomy. Postoperative course was uneventful, and the followed up for each of them was 3 year and 18 months without any evidence of recurrence.

  • Cancer of the oral cavity and pharynx represents the 7th most diagnosed malignancy in Spain. Mucoepidermoid carcinomas are the most frequent malignancies of the minor salivary glands of oral cavities. The purpose of this report is to describe the very rare case of an alveolar ridge high-grade mucoepidermoid carcinoma presenting as an inside socket radiolucent lesion, simulating an apical cyst. The patient was diagnosed in our unit for oral and maxillofacial surgery and treated with surgery and adjuvant radiotherapy. The patient continues to be free of recurrent/persistent, local/regional disease after two years of follow up. Non-healed tooth related lesions present for more than one year are strongly recommended to be biopsied and evaluated histopathologically.

  • Mucoepidermoid tumors of lung are extremely uncommon, with fewer than 50 such cases having been reported. The degree of tumor malignancy has been discussed by some authors without any definite conclusion. This report describes a case of this, occurred in a 53-year-old female, having a highly malignant process and finally confirmed by postoperative histopathological evaluation.

  • To evaluate the diagnostic findings of salivary gland tumors, we reexamined aspiration cytology smears of 7 cases of pleomorphic adenoma, 3 cases of adenoid cystic carcinoma, and 3 cases of mucoepidermoid carcinoma, performed during April 1986 to March 1990, which were comfirmed by surgical excision and histologic diagnosis. The results obtained are summarized as follows : 1. All cases of pleomorphic adenoma showed branching cellular clusters of epithelial and myoepithelial cells. Acellular elements including myxomatous and chondroid components were observed. There were no cellular pleomorphism and nucleoli. Keratinizing squamous epithelial cells and keratin pearls were noted. 2. The smears of adenoid cystic carcinoma showed cell bails or cell cords containing a central hyaline core. Nuclear atypism and the nucleoli were frequently observed. There were no keratinizing squamous epithelial cells. 3. The smears of mucoepidermoid carcinoma showed mainly sheets or clusters of intermediate cells and some mucin-producing cells. Some nuclear pleomorphism was observed. Mucinous material and many inflammatory cells were present in the background.
