Mucoe;idermoide Lung Carcinoma in Child. Recurrent pneumonia in the same region of the lung should raise clinical suspicion of an endobronchial lesion or mass, such as mucoepidermoid carcinoma. Directory of Open Access Journals Sweden. Mucoepidermoid carcinoma is an uncommon neoplasm of the tracheobronchial tree, of unknown etiology.
Its preferred endobronchial location often results in respiratory symptoms such as obstruction of the airways and lung diseases of slow recovery. They usually are slow growing tumors although they may present an aggressive behavior with local invasion and lymph node metastases depending on their histopathologic characteristics.

The mainstay therapy is complete surgical resection either by means of lobectomy or by lung sparing procedures such as bronchotomy and bronchoplasty.
Prognosis depends upon the degree of cellular differentiation of the tumors. The authors report a case of this rare neoplasia and describe the clinical and radiographic characteristics, and the surgical treatment.
Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands. However, it is a rare entity in larynx. Laryngeal cases are frequently misdiagnosed with other malignancies and they are under-reported.
So, recognizing the clinical and histological features of this tumor is essential. Laryngeal mucoepidermoid carcinoma can arise in supraglottis, glottis and subglottis. Generally, it presents as a submucosal mass; therefore, progressive symptoms without any identifiable lesion in Mucoepidermoid carcinoma of the anterior maxilla: Full Text Available Mucoepidermoid carcinoma is the second most common salivary gland tumor primarily involving major salivary glands and intraoral minor salivary glands.
Although rare, it can occur in the jaw bones, but it is very rare in the maxillary anterior region. Here, we present a case of mucoepidermoid carcinoma occurring in maxillary anterior region in a year-old male patient presented as painless swelling clinically appearing similar to a periapical or nasopalatine cyst. The final diagnosis of this lesion was made after microscopic examination of biopsy specimen.
Mucoepidermoid carcinoma of lung masquerading as urothelial carcinoma of bladder.
Background Mucoepidermoid carcinoma MEC of the lung is a rare subtype of non-small cell lung cancer. There is no consensus regarding optimal management for this disease. Case report We present a case of MEC of the lung in a 75 year-old female geado a history of superficial urothelial carcinoma of the bladder. The patient akto found to have an asymptomatic lung mass. Initial biopsy suggested metastatic recurrence of urothelial carcinoma and therefore, cisplatin and gemcitabine chemotherapy was administered prior to surgical resection.
Pathological analysis of the resected specimen confirmed a diagnosis of stage IIIA MEC with focal high-grade features including transitional cell-like areas. Adjuvant muciepidermoide was administered due to a positive microscopic resection margin.
grdo No chemotherapy was given due to lack of supporting data. The patient developed widespread metastatic disease 3 months following completion of mucoepidwrmoide and died 1 month later.
Conclusion This case demonstrates the possibility of dual pathology in cases where metastatic disease is suspected. The use of small tissue samples may complicate diagnosis due to the heterogeneity of malignant tumours. Mucoepidermoid carcinoma of the conjunctiva with lung metastasis.
Full Text Available A year-old lady presented with redness and decreased vision in right eye since 6 months. She was earlier diagnosed of cavitary mucoepicermoide lesion, presumed secondary to tuberculosis and treated with anti-tubercular treatment for 4 months. A diagnostic ccarcinoma biopsy of uveal mass revealed malignant cells. Computed tomography-guided lung biopsy revealed squamous cell carcinoma SCC, indicating metastatic spread from the orbit.
She underwent lid-sparing exenteration of the mucoepieermoide eye. Histopathological examination of the orbital tissue revealed mucoepidermoid carcinoma arising from the conjunctiva with extensive invasion into the orbital tissue, muscle fibers, sclera, choroid and optic carcinooma.
Multiple tumor emboli were seen in the lumen of orbital blood vessels. In conclusion, mucoepidermoid carcinoma of the conjunctiva is a rare, aggressive variant of SCC.
Early intervention is essential to prevent intraocular invasion and systemic metastasis. Mucoepidermoid carcinoma of parotid gland: Full Text Available Mucoepidermoid carcinoma MEC is the most common malignant neoplasm of the major salivary glands, accounting for The aim of this article is to report a case of MEC in a years-old male patient who presented with a painless firm fluctuant swelling in left preauricular area.
The lesion was mucoepidermoude examined preoperatively, and investigations were carried out. Fine-needle aspiration cytology was done for the lesion and report suggested tumor of the parotid gland. Superficial parotidectomy procedure was done, taking care not to injure the lower division of the facial nerve.
Post recovery was uneventful with no defect of facial nerve functions. The histologic picture confirmed that the tumor was MEC of parotid gland. Through the literature reviews of MEC the discussions on prevalence, origin, diagnosis, histological finding, investigation and the modes of treatment are made.
In cases of recent asthma in which clinical control with the usual treatment corticosteroids and bronchodilator is unsatisfactory, it is important to consider mucoepidermokde diagnoses, such as congestive heart failure, gastroesophageal reflux or other forms of airway obstruction.
We report the case of a female patient with mucoepidermoid carcinoma of the trachea mimicking asthma. The patient presented cough and wheezing, as well as abnormal spirometry results with an muvoepidermoide pattern that was responsive to bronchodilators.
One year later, the patient presented clinical and spirometric worsening.

The chest X-ray revealed no abnormalities. Primary pulmonary mucoepidermoid carcinoma: Full Text Available Abstract Background The optimal brado for pulmonary mucoepidermoid carcinoma MEC, a rare type of tumor, has not been established yet. This study analyzed the survival of pulmonary MEC patients and attempted to find clues for optimal treatment.
Methods A total of 21 patients with pulmonary MEC from November to January were included in the investigation. Immunohistochemistry, epidermal growth mucoepidsrmoide receptor EGFR mutation, and survival were retrospectively studied. Results Among the 21 pulmonary MEC patients, 17 were diagnosed with low-grade malignancy and 4 with high-grade malignancy through pathological examination. The prognosis was found to be poor in the presence of lymph nodes. The mutation rate of EGFR was 0.
Log-rank test results indicated that age, grade, lymph node metastasis, and tumor-node-metastasis stage were prognostic factors. Conclusion Age, grade, lymph node metastasis and tumor-node-metastasis stage correlate with the survival of pulmonary MEC patients. Trial registration This study was approved and registered by the Ethics Committee of Zhongshan Hospital. Written informed consent was obtained from all participants prior to treatment. Treatment of tracheal mucoepidermoid carcinoma by argon plasma coagulation during pregnancy.
Mucoepidermoid carcinoma of the tracheobronchial tree is a rare airway tumor cesarean section. A 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.
Mucoepidermoid carcinoma of the lung with initial presentation of microangiopathic hemolytic anemia and thrombocytopenia. Full Text Available Mucoepidermoid carcinoma is a rare entity of lung malignancy that is subclassified into high-grade or low-grade types according to its histological features.
High-grade mucoepidermoid carcinoma is a more aggressive form of malignancy, with a tendency towards lymph node involvement and distant metastasis. Cancer-related microangiopathic hemolytic anemia as a less common situation of paraneoplastic syndrome may be encountered with metastatic malignancy, but has not been reported previously in mucoepidermoid carcinoma of the lung.
Herein, we report a year-old male patient who alfo with hemoptysis for one day. Laboratory tests showed microangiopathic hemolytic anemia and thrombocytopenia. A chest X-ray demonstrated consolidation in the left lung field.
Chest computed tomography revealed a mass in the left upper lobe, and a subsequent bronchoscopic biopsy was performed. The histopathological results indicated a high-grade mucoepidermoid carcinoma. Magnetic resonance imaging of the brain demonstrated leptomeningeal carcinomatosis.
The patient refused systemic chemotherapy, and palliative radiation therapy only was conducted for local disease control. The patient has performed well for 12 months to date since diagnosis of the tumor.
Long term control of a maxillary sinus mucoepidermoid carcinoma with low dose muocepidermoide therapy: Mucoepidermoid carcinoma of the maxillary sinus is a rare malignancy of the head and neck. The location of this tumour near vital structures and its large size at presentation makes surgical resection with negative margins challenging. In incurable cases, relief from symptoms such as epistaxis may be achieved with radiation therapy.
