Mucoepidermoid carcinoma of the trachea is rare. Its occurence in a 14-year-old boy is reported here. This case illustrates the typical course of tracheal tumors with clinical manifestations of cough, wheezing, and hemoptysis, the intially reported normal chest roentgenogram, and the common failure to diagnose tracheal tumor for several months. Early use of tomographic studies and bronchoscopic examination in any person with recent onset of airway obstruction unresponsive to bronchodilator therapy is recommended.

Mucoepidermoid carcinoma of trachea and bronchi is a rare tumor, especially in children. The authors report a case of 9-year-old boy with mucoepidermoid carcinoma at the carina. His presenting symptoms were hemoptysis of recent onset and intermittent cough of 2 years' duration. Preoperative assessment of the tumor was an intraluminal polypoid mass arising from the carina extending into the trachea and right main stem bronchus. A complete resection with reconstruction of carina was successful. The tumor was 12 mm in size, polypoid with a broad base. It had characteristic features of a low-grade mucoepidermoid tumor, namely, admixture of islands of intermediate cells and glandular components with invasion of submucosa. The patient is now 15 months postsurgery free of disease.

A 16-year-old girl was hospitalized because of anemia and thrombocytopenia in April 1998, and was diagnosed as having AML (FAB:M2). After failure of initial remission induction therapy, she was successfully treated with the MEC regimen as a second-line chemotherapy. On June 22, the first consolidation therapy was started. One week later, the patient developed a high fever with backache. Chest computed tomography (CT) on July 8 showed a 3cm mass lesion adjacent to the thoracic descending aorta in the left upper lobe. She was given fluconazole and antibiotics, and remained in remission. On July 24, the mass lesion changed to a cavitary lesion on chest CT, suggesting a fungal infection, probably aspergillosis. With recovery from neutropenia, the patient became asymptomatic, and fluconazole was changed to itraconazole. On July 27, she suffered sudden, massive hemoptysis and died. Autopsy revealed a localized adhesion between the cavitary lesion and the thoracic descending aorta, and the aortic wall was ruptured at this site. Microscopic examination revealed invasion of mucormycotic hyphae into the wall of the aorta with infiltration of inflammatory cells. The vasa vasorum were occluded by thrombi, in which mucormycotic hyphae were detected.

Mucoepidermoid carcinoma of the trachea is a rare tumor. This investigation reports on a case of a 67-year-old male with mucoepidermoid carcinoma in the lower 1/3 of the trachea. The patient presented with intermittent coughing and hemoptysis lasting for 1 month. The preoperative investigation revealed an intraluminal polypoid mass in the posterolateral trachea with 75% stenosis of the tracheal lumen. A rigid bronchoscope was used to evaluate the airway before surgery, and the tumor was mechanically resected using the tip of the rigid bronchoscope just before intubation. Finally, the tumor was completely removed, and the airway was successfully reconstructed. At 6 months after surgery with no adjuvant chemoradiotherapy, the patient was free of disease.

Two adolescents presented with a history of dyspnea upon exertion and cough. In both cases, the chest X-ray and pulmonary function testing, including flow-volume loop, were normal. A bronchial tumor was diagnosed by CT scan, which was ordered after each patient had an episode of hemoptysis. The sedimentation rate was the only abnormal laboratory test in both cases. Mucoepidermoid carcinoma of the bronchus, a rare tumor in childhood, was found at pathology in both cases. There was no evidence of metastases to local lymph nodes or distal sites. There were 47 previously reported cases in children. Recurrent pneumonia and persistent cough were the most common presenting findings. These tumors are of low-grade malignant potential but they can become locally invasive, extending into cartilage and surrounding soft tissue. Prognosis is good with complete resection.

Mucoepidermoid carcinoma of the tracheobronchial tree, which is thought to arise from the minor salivary gland tissue of the proximal airway, is an extremely rare neoplasm. We herein report a case of a 31-year-old pregnant woman in her 36th week, who complained of recurrent hemoptysis from bronchial mucoepidermoid carcinoma. As massive bleeding from the tumor was seen during a caesarean section, it was necessary to add bronchial artery embolization. The tumor was successfully removed by a sleeve resection of the left main bronchus after the embolization. The patient is doing well without any signs of recurrence at 3 years after undergoing the operation.

Mucoepidermoid carcinoma (MEC) of the lung is a rare endobronchial tumor accounting for up to 0.2% of primary lung cancer. We report a patient with MEC who presented with cough, hemoptysis, and localized findings on chest examination. This case emphasizes the importance of obtaining adequate biopsy to establish the correct diagnosis. In addition, it highlights that MEC of the lung usually presents in the low-grade form, carrying a favorable prognosis.

Primary pulmonary neoplasms rarely occur in children, but the majority of those that do are malignant. Mucoepidermoid carcinoma (MEC) represents ~10% of all primary pulmonary malignant tumors. However, MEC is not usually considered in the clinical differential diagnosis in pediatric practice. The present study presents the case of a seven-year-old female with a one-year history of recurrent hemoptysis. Computerized tomography (CT) scans revealed a tumor originating in the right lower lobe bronchus. The patient did not receive any radiation and chemotherapy following a lobectomy on the right lower lung. The tumor was histopathologically determined to be an MEC of the tracheobronchial tree. Subsequent to a six-year follow-up, the MEC was undetectable in this patient, according to the clinical and radiological evidence. The literature with regard to pediatric MEC is also reviewed in this study.

Mucoepidermoid carcinoma (MEC) is a rare malignant tumor arising from the bronchial gland. A case of 6-year-old male child who presented with fever, hemoptysis and wheezing since 1month is reported. Chest X-ray showed features suggestive of foreign body with post-obstructive pneumonia and was treated for the same with medication without much improvement. Subsequently computerized tomography scan chest was carried out, which showed oval mass with speculated margin in right hilar region with distal segmental atelectasis. Bronchoscopy showed small growth with nodularity in the apical segmental bronchus of the right lower lobe with mucosal erosion and hence carried out broncho-alveolar lavage showed few atypical squamous cells. Patient underwent right lower lobectomy, which showed a grey white oval mass with solid and cystic areas in the right hilar region with extension in to the lung parenchyma. Histology of the tumor showed mixed solid and cystic areas with sheets of epidermoid cells and mucus-filled cysts of irregular size. Areas of solid growth were composed of squamoid and intermediate cells. Hence, the final diagnosis of mucoepidermoid carcinoma (MEC) intermediate grade of the lung was made. Early diagnosis can be accomplished if the clinician is alert to persistent pneumonia, coughing and tumor obstruction on image studies. MEC is a comparatively rare low-grade tumor, which reportedly carries a good prognosis with early surgical intervention.

Mucoepidermoid carcinoma of the tracheobronchial tree is a rare airway tumor (<1% of all lung tumors). In adults, the majority of primary tracheal tumors are malignant. Management during pregnancy is complex and requires weighing maternal and fetal prognosis. Reported cases describe surgical resection following cesarean section. We report the first case to be treated by Argon-Plasma Coagulation (APC) in pregnancy. A 35-year-old Caucasian woman G1P0, at 27 weeks of gestation was admitted to the emergency department because of hemoptysis and severe dyspnea. Bronchoscopy and biopsies diagnosed primary tracheal mucoepidermoid carcinoma. Following an episode of tracheal bleeding, she was intubated. After thorough explanations to the family and obtaining informed consent, therapeutic bronchoscopy, under general anesthesia using a rigid bronchoscope, was performed. The tumor was cored out with the tip of the bronchoscope and removed with an alligator forceps. The tumor bed was coagulated with APC. The obstetrical team was ready to intervene in case of maternal emergency. Immediate follow-up was good, and she left the hospital 4 days later. She delivered at 39 weeks of gestation by cesarean section because of dystocia. Five years later, the patient is doing well without any signs or symptoms of recurrence. Pediatric follow-up is normal. Argon Plasma Coagulation for treatment of mucoepidermoid tracheal carcinoma is feasible during pregnancy. Reporting this case could lead to less aggressive management of mucoepidermoid carcinoma in pregnant patients.
