Background: Parotid gland tumor is a quite common pathology in salivary gland tumor. The exact diagnosis for parotid gland tumors has an important significance because it will help to plan appropriate surgical strategies. Objective: To remark some characteristics of ultrasonographic image of the parotid gland tumors and evaluate the role of ultrasonography in diagnosis of the parotid gland tumors. Subject and methods: A cross-sectional, descriptive study was conducted on 24 patients with parotid gland tumors, operated on at the Department of Plastic and Maxilofacial Surgery of Hospital 103 and the Department of Odonto - Stomatology of Ha Dong General Hospital, Hanoi from January, 2007 to July, 2008. Results: The size of tumors was 2-4cm (58.33%), 21/24 of tumors were in superficial lobe areas. 46.66% of pleomorphic adenomas had a lobulated shape. 2/3 of Warthin\u2019s tumors had an oval shape. 79.17% of the benign lesions were well-defined. 87.5% of all tumors had echogenicity decreased. Almost equal percentages of Warthin\u2019s tumors were echogenicity decreased and structure in heterogeneous. Conclusion: Ultrasonography is a useful method in the diagnosis of the parotid gland tumors, helping to determine clearly the natural basis of some tumors and contributing to early screening for acute parotid gland tumors.

Carcinoma exmixed tumor is a mixed tumor in which a second neoplasm develops from the epithelial component that fulfills the criteria for malignancy. This tumor occurs frequently in the parotid glands. Individuals in whom carcinoma ex mixed tumor have a past history of benign mixed tumor. These lesions contain both a benign mixed tumor as well as a malignant neoplasm. We report a case of carcinoma ex mixed tumor which occurred in the parotid gland. A 67-year-old woman presented with movable right mass. she complained pain and facial paralysis. The clinical presentation, several diagnostic images, and histopathologic findings are presented.

gland tumors. Although rare in children, it is the most common "malignant"salivary gland tumor, having been reported in major and minor (intraoral) salivary gland sites as well as in the maxilla and the mandible. In children, as in adults, it most often occurs in the parotid gland, but a significant percentage is found in the palate. Presently, there is no unanimity of opinion about whether to consider all mucoepidermoid tumors malignant or what the most appropriate treatment regimen is. The importance of submitting, for microscopic diagnosis, all tissue removed during surgical procedure is illustrated in this case report and a review of the literature is presented.]]>

Carcinosarcomas, also known as true malignant mixed tumors, are rare tumors of the salivary gland and are composed of both malignant epithelial and malignant mesenchymal elements. They may occur in pre-existing pleomorphic adenomas or arise de novo. Here we report the first case of carcinosarcoma of the parotid gland composed of mucoepidermoid carcinoma and osteosarcoma. The tumor had originated from the parotid gland and extended into the parapharyngeal space. To the best of our knowledge, there have been no reports on mucoepidermoid carcinoma mixed with osteosarcoma ex pleomorphic adenoma in the parotid gland.

Carcinoma ex pleomorphic adenoma of the salivary gland is a relatively uncommon tumor that accounts for roughly 4% of all malignancies at this location. The lesion occurs when a malignant tumor arises in the epithelial component of a pleomorphic adenoma. It usually arises in the parotid gland. Typically, it is a high grade carcinoma, frequently leading to metastasis and disease-related death. We experienced a case of a salivary duct carcinoma that arose in the epithelial component of a pleomorphic adenoma in the parotid gland with neck metastasis. After total parotidectomy and modified radical neck dissection, he was given 10, 980 cGy of radiation postoperatively for 7 weeks. The clinicopathologic feature of this tumor are presented with a review of literatures.

Carcinosarcoma, or true malignant mixed tumor of the salivary gland, is a very rare malignant tumor comprised of both carcinomatous and sarcomatous elements and accounts for only 0.04-0.16% of all salivary gland tumors. Carcinosarcoma usually occurs in the parotid gland. Other locations including submandibular gland, minor salivary gland, uterus, bladder or lung have been reported. We report a rare case of carcinosarcoma of the parotid gland in an 85-year-old female. The tumor was large, about 19x17 cm in size, and was successfully excised.

OBJECTIVETo investigate the prognosis-related factors and treatment strategy of primary parotid squamous cell carcinoma.

METHODSForty-nine primary parotid squamous cell carcinoma treated from 1970 to 2005 were retrospectively analyzed. The follow up data were analyzed by SPSS 13.0 software.

RESULTSIntegrated follow up data were obtained from 44 patients with a median follow up time of 38 months (5 - 215 months). Recurrence or distant metastasis of the carcinoma occurred in 21 patients, including 13 local recurrence in parotid or neck and 8 distant metastasis. Local recurrence was the main reason of treatment failure. The 3-year and 5-year survival rate and disease-free survival rate was 52%, 27% and 34%, 16%. Kaplan-Meier and log-rank analysis indicated that age, tumor size, distant metastasis, postoperative radiotherapy, facial nerve dysfunction, neck dissection, skin invasion, and surgical margins were prognosis-related factors. Cox analysis showed that age, facial nerve dysfunction, distant metastasis and surgical margins were the important factors that influenced the prognosis.

CONCLUSIONSPrimary parotid gland squamous cell carcinoma is an uncommon tumor, surgery and postoperative radiotherapy are the optimal treatment, which can improve the prognosis of the patients and decrease recurrence of the tumor.

parotid region, 4. Masses in the medianparamedian region, 5. Masses in the lateral neck region. The lateral neck region is the area posterior to the hyolaryngotracheal conduit, below the posterior belly of the digastric muscle and tip of the parotid gland, and extends down to the clavicle.The contents of this region include the large vessels, nerves and greatest number of lymph nodes of the neck,and lymph node metastasis in this region is usually from a primary lesion at the base of the tongue or elsewhere in the oropharynx. Common lateral neck masses include branchial cleft cyst, carotid body tumor, neurogenic tumor, panneck infection,cystic hygroma,hemangioma,lipoma and lymphoma. Especially lymphosarcoma, Hodgkin's disease, cystic hygroma, hemangioma and branchial cleft cyst and more common and often manifest in the young patients. Many head and neck disease processes manifest as neck masses. These conditions are treated by surgical excision, except for some inflammatory masses, and often those also must be excised before a diagnosis can be made. We retrospectively reviewed 5-year experiences in the treatment of lateral neck masses at our department to define better clinical characteristics of the masses and the optimal diagnostic and therapeutic approaches to these rare diseases.]]>

The authors analyzed retrospectively the 36 patients with malignant salivary gland tumors who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from February, 1989 to September, 1997. The results obtained were as follows: 1. There were 14 males( 38.9%) and 22 females(61.1%). The peak age of patients with major salivary gland tumors was the 6th decade, but with minor salivary gland was the 5th decade. 2. Of all salivary gland tumors, 5 cases arose in the parotid glands, 2 cases in the submanibular glands, 1 case in the sublingual gland and 28 cases in the minor salivary glands. 3. The incidence according to the anatomic primary site for minor salivary glands was 15 cases in the palate, 5 in the floor of mouth and 2 cases each arising in the tongue, lip, retromolar area and buccal mucosa. 4. Of all salivary gland tumors, adenoid cystic carcinoma was 5 cases in the major salivary glands and 8 in the minor salivary glands. mucoepidermoid carcinoma was 2 cases in the major salivary glands and 14 in the minor salivary glands and others were 2 cases of adenocarcinoma, 4 malignant mixed tumors and 1 undifferentiated carcinoma. 5. The incidence of cervical lymph node metastasis was 100%(2/2) in the submandibular glands, 80%(4/5) in the floor of mouth, 50%(1/2) in the tongue and 20%(1/5) in the parotid glands. The highest incidence of lymph node metastasis according to histopathological classfication was found in the high grade of mucoepidermoid carcinoma and tubular type of adenoid cystic carcinoma. 6. Nerve invasion was common in the adenoid cystic carcinoma. 7. The lung was the commonest site for distant metastasis comprising 7 cases among 7 cases in which distant spread occurred.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.
