1/9. 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 = 1keywords = mandible, jaw (Clic here for more details about this article) |
2/9. 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 = 1keywords = mandible, jaw (Clic here for more details about this article) |
3/9. 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 = 6.7844588151644keywords = mandible (Clic here for more details about this article) |
4/9. 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 = 7.7536672173308keywords = mandible (Clic here for more details about this article) |
5/9. Central mucoepidermoid carcinoma of the mandible in a child.Central mucoepidermoid carcinoma is an uncommonly encountered tumor. A rare case of this malignant tumor arising in the mandible of a 14-year-old adolescent is presented. Symptoms, signs, and management approach are discussed. A literature review of similar previously described cases is discussed as well.- - - - - - - - - - ranking = 4.8460420108317keywords = mandible (Clic here for more details about this article) |
6/9. Primary intraosseous (central) salivary gland neoplasms in jaw bones: report of a mucoepidermoid carcinoma of the mandible diagnosed by fine-needle aspiration cytology.A case of intraosseous (central) mucoepidermoid carcinoma of the mandible diagnosed by fine-needle aspiration (FNA) cytology, with the diagnosis confirmed by surgical resection of the tumor is presented. Mucoepidermoid carcinoma is the most common histotype of malignant and benign salivary gland tumors, which occasionally arise within the facial bones of mandible and maxilla, besides their ordinary derivation from the major and minor salivary glands of the head and neck regions. This case is unusual in that although tumors of the jaws abound, only rare reports of intraosseous salivary gland-type lesions sampled by FNA exist. The current concepts exploring the intraosseous derivation of salivary gland tumors are presented and certain points on FNA technic for adequate sampling of such lesions are related.- - - - - - - - - - ranking = 5.9692084021663keywords = mandible, jaw (Clic here for more details about this article) |
7/9. Glandular odontogenic cyst: a case report and clinicopathologic analysis of the relationship to central mucoepidermoid carcinoma.Glandular odontogenic cyst (GOC), an unusual multilocular cystic lesion of jaws exhibiting the features of both botryoid odontogenic cyst and mucoepidermoid tumor has been reported recently as a new entity with uncertain histogenesis. The world health organization named GOC as an independent pathologic entity and classified it as a developmental odontogenic epithelial cyst. We report an additional case, describe its clinicopathologic features, and discuss the similarity to the central mucoepidermoid carcinoma.- - - - - - - - - - ranking = 0.030791597833652keywords = jaw (Clic here for more details about this article) |
8/9. Vertical ramus compartment resection of the mandible for deeply invasive tumors.PURPOSE: Vertical ramus compartment resection of the mandible is indicated in the management of pathology that originates in the ascending ramus or condyle of the mandible and invades the pterygomaxillary fossa, infratemporal space, parapharyngeal space, masseter muscle, or medial pterygoid muscle. This article describes the technique, presents a review of the relevant literature, and reports the outcome of five cases. patients AND methods: A retrospective review of all cases operated on by the senior author (R.A.O.) over the last 5 years at the University of maryland was performed. The records of these cases were reviewed to identify patient sex, age, pathologic diagnosis, use of adjuvant therapy, and status after resection. RESULTS: Five surgical cases in which a vertical ramus compartment resection of the mandible was necessary were identified. The histologic diagnoses of these five cases were as follows: grade II chondrosarcoma, peripheral neuroectodermal tumor, high-grade central mucoepidermoid carcinoma, invasive squamous cell carcinoma, and odontogenic keratocyst. Four of the five patients are alive and well at follow-up of 16 to 43 months. The only death occurred in a 70-year-old man with squamous cell carcinoma that recurred intracranially by local extension. CONCLUSIONS: When indicated by local extension or tumor biology, vertical ramus compartment resection of the mandible is a viable surgical modality that allows clearance of local disease in most well-selected cases.- - - - - - - - - - ranking = 7.7536672173308keywords = mandible (Clic here for more details about this article) |
9/9. Central mucoepidermoid carcinoma.A case of central mucoepidermoid carcinoma of the mandible is presented along with a review of the literature.
