1/24. Mucoepidermoid carcinoma of the eyelid skin.PURPOSE: Mucoepidermoid carcinoma involving the eye or its adnexa generally arises from the conjunctiva. We describe a nodular lesion of the lower eyelid skin with histologic features consistent with low-grade mucoepidermoid carcinoma. METHOD: Case report. RESULTS: By histology, the tumor demonstrated areas of squamous cell carcinoma and scattered islands of mucin-secreting cells. Histochemistry showed hyaluronidase-resistant mucin and intense immunoreactivity with an antibody against carcinoembryonic antigen suggesting that the tumor originated from acrosyringeal structures. CONCLUSIONS: To our knowledge, this is the first report of a mucoepidermoid carcinoma arising from sweat glands in the eyelid skin.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
2/24. Mucoepidermoid carcinoma of the bronchus.bronchoscopy in a 4.5-year-old girl with recurrent pneumonia showed an exophytic endobronchial mass. biopsy disclosed microscopic and ultrastructural features of a low-grade mucoepidermoid carcinoma. Complete cure was accomplished by surgical removal of the tumor and right lower lobe.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
3/24. Co-occurrence of mucoepidermoid carcinoma and squamous cell carcinoma of the esophagus: report of a case.A case of co-occurrence of a mucoepidermoid carcinoma (MEC) and a squamous cell carcinoma (SCC) in the esophagus is described. The present patient was a 61-year-old man who underwent a curative esophagectomy with a regional lymph node dissection for a MEC in the lower esophagus and a SCC near the esophagogastric junction. The two lesions were endoscopically and histologically divided by a normal esophageal mucosa. The MEC of the esophagus consisted of SCC cells and signet-ring cells, and a mucin product and carcinoembryonic antigen, which were found at high levels in the blood serum before surgery, were detected histochemically in the signet-ring cells. The follow-up survey of the patients with esophageal MEC previously reported in japan showed that most of the patients died of either local recurrence or widespread metastasis after treatment; the overall 5-year survival rate was 24.4% in the total 25 cases, and 27.7% in the 22 resected cases. However, 6 patients who died of therapeutic complications were included among these patients; furthermore, the 5-year survival rate after surgery was 29.2% in the patients treated over the last decade (1989-1998). We expect that the clinical outcome of patients treated for esophageal MEC will therefore improve in the future.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
4/24. Intraosseous mucoepidermoid carcinoma. Report of a long-term evolution case.Primary central mucoepidermoid carcinoma (CMC) of the jaws accounts only for 2-3% of all mucoepidermoid carcinomas reported. Bhaskar in 1963 first analysed the criteria for his central origin, histology and pathogenesis. The authors report a long-term evolution case of CMC of the mandible with peculiar clinical features observed at the Department of Maxillo-Facial Surgery of the School of medicine and Surgery of the "Federico II" University of Naples (Naples, italy) examining histopathologic and clinical features and problems related to the treatment.- - - - - - - - - - ranking = 134.64924556213keywords = mandible (Clic here for more details about this article) |
5/24. Intrapulmonary lymph nodes enlarged after lobectomy for lung cancer.A 62-year-old man, who had had a left upper lobectomy for mucoepidermoid lung carcinoma, was admitted again 3 months later because of enlargement of four small nodules in the left lower lobe. A computed tomography-guided needle aspiration biopsy obtained insufficient material for diagnosis, and because pulmonary metastases were suspected, two of the four tumors were extirpated. Intraoperative frozen section found the nodules to be intrapulmonary lymph nodes. Intrapulmonary lymph nodes should be included in the differential diagnosis of coin lesions in the peripheral lung field.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
6/24. Video-assisted sleeve lobectomy for mucoepidermoid carcinoma of the left lower lobar bronchus: a case report.We report what we believe to be the first case of video-assisted sleeve lobectomy in an adolescent girl who had experienced recurrent episodes of lobar pneumonia and received a diagnosis of low-grade mucoepidermoid carcinoma of the left lower lobar bronchus.- - - - - - - - - - ranking = 5keywords = lower (Clic here for more details about this article) |
7/24. Central mucoepidermoid carcinoma--a case report.The mucoepidermoid carcinoma (MEC) account for approximately 6-8 Percent of all salivary gland tumors. Central mucoepidermoid carcinoma of the jaws is rare. Following is a case report of central mucoepidermoid carcinoma which involves the ramus of the mandible. Origin of the central mucoepidermoid carcinoma is discussed.- - - - - - - - - - ranking = 134.64924556213keywords = mandible (Clic here for more details about this article) |
8/24. A large glandular odontogenic cyst of the mandible: report of case.Glandular odontogenic cyst (GOC) is generally considered uncommon, but several investigators claim there is a more frequent occurrence than previously thought. However these case reports lacked confirming data to validate their claim. On the other hand, it is possible that cases of central mucepidermoid carcinoma or later periodontal cyst might be viewed as glandular odontogenic cyst. This is a report of a case of a 70-year old male who presented with a firm swelling in the right side of his edentulous mandible. Radiographic examination revealed a multilocular radiolucent lesion in the mandible extending from the right first premolar to the left second premolar and reaching the inferior mandible. Clinical findings, the health history, and microscopic examination of excised tissue confirmed the diagnosis of GOC. The lesion was excised and post-operative healing was uneventful.- - - - - - - - - - ranking = 942.54471893491keywords = mandible (Clic here for more details about this article) |
9/24. Central mucoepidermoid carcinoma of the mandible: report of four cases with long-term follow-up.Central mucoepidermoid carcinomas are uncommon tumours, representing about 2 to 4% of all mucoepidermoid carcinomas. They are histologically low-grade cancers, usually affecting the mandible as uni- or multilocular radiographic lesions. The authors report four cases of central mucoepidermoid carcinomas affecting the mandible and discuss their clinical, radiographic and histological findings. Four females were affected, with a mean age of 42 years and all cases involved the posterior mandible. Treatment included surgery in three cases and surgery associated to neck dissection and radiotherapy in one case. Two patients showed no recurrence and were alive without signs of the disease after a mean follow-up of 78 months. The other two patients showed local recurrence and one was alive with disease after a follow-up of 384 months, and the other was followed-up for 324 months dying by other causes without signs of the tumour. Central mucoepidermoid carcinomas of the mandible are low-grade tumours, and effective surgical treatment involving wide local excision or en bloc resection allows patients to have a favourable prognosis after long-term follow-up.- - - - - - - - - - ranking = 1077.193964497keywords = mandible (Clic here for more details about this article) |
10/24. Successful treatment of tracheal mucoepidermoid carcinoma using rigid bronchoscopy combined with conventional surgical resection.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.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
