Mucoepidermoid carcinoma (MEC) of the larynx is one of the rarest tumors in the pediatric age group. Our review of the English-language literature found only 1 previously reported case of a laryngeal MEC in a child. We present what to the best of our knowledge is the first case of a pediatric MEC of the larynx with transglottic involvement. Our patient was a 12-year-old girl who presented with long-standing hoarseness and recent dysphagia, breathing difficulty, and pain radiating to the left ear. Investigation revealed the presence of an endophytic mass in the larynx. Histopathologic examination of biopsy tissue identified the mass as a low-grade MEC. The patient was scheduled to undergo a total laryngectomy 1 week later, but she did not report for surgery. Three weeks later, she presented to the emergency department in a semiconscious state and in respiratory distress. Despite all resuscitative measures, she died.

Mucoepidermoid carcinoma of the lung is exceedingly rare. Our case involves a 58-year-old male who presented with shortness of breath, dysphagia, and weight loss. He denied ever smoking. Chest x-ray revealed trapped lung, and CT demonstrated a right bronchial mass. Diagnosis of lung carcinoma was made by bronchoscopic FNA biopsy. EGFR mutation was negative. Staging workup demonstrated evidence of advanced disease. Performance status was good, and it was decided to start chemotherapy and radiation for palliation. Lung carcinomas often present as an obstructing hilar mass. There are different histological grades that affect progression and survival. Though uncommon, metastatic spread has been previously reported. Studies have investigated the possible role of tyrosine kinase inhibitors in both EGFR-mutated and non-mutated cases. Unfortunately, there has been little consensus as to which therapies are most beneficial.

Mucoepidermoid carcinoma (MEC) is typically located in the salivary, lacrimal, and tracheobronchial glands and rarely presents in the esophagus. MEC is commonly characterized by squamous cells, mucus-secreting cells, and intermediate cells. This report presents the case of a 57-years-old male with a three months history of cough and shortness of breath. Computer tomography (CT) scans revealed a tumor locating in the left hilar. The histological report was squamous carcinoma. After three circles of chemotherapy, the patient complained of dysphagia. The electronic gastroscope showed a protrusion which 30-34 cm from the incisors. The tumor was histopathologically determined to be MEC of esophagus. The patient refused to surgery and concurrent chemoradiotheray; so, radiotherapy and sequential chemotherapy were performed, and after one year of follow up, the disease of esophagus recurrence; the patient was died of hemorrhage of esophagus for tumor progression. The literatures of MEC are also reviewed in this study.
