The authors reviewed 95 cases(46 men and 49 women) of the orbital tumors diagnosed histopathologically at the Department of Ophthalmology, Yeungnam University Hospital from March 1984 through August 1994. Seventy-five cases of benign tumors were found evenly in all decades, but twenty cases of malignant tumors were noticed more frequently in 1st, 6th, and 7th decades. The frequency of benign orbital tumors was in this order; dermolipoma(21%, 20 cases), dermoid cyst(11.6%, 11 cases), mucocele(8.4%, 8 cases), lipoma(7.4%, 7 cases) and pleomorphic adenoma(5.3%, 5 cases). Of malignant orbital tumors, the frequency was in this order; retinoblastoma(3 cases), malignant melanoma(2 cases), sebaceous carcinoma(2 cases), and maxillary sinus carcinoma(2 cases). Malignant orbital tumors of 8 expired patients were revealed as secondary or metastatic tumors.

Minor salivary gland tumors vary in their primary sites, histopathology and bilogical behavior. Therefore various factors are considered in selecting the treatment modality and predicting the prognosis. The prognosis of milignant tumors of minor salivary glands are worse than that of such lesions of major salivary glands. Authors experienced 26 cases of minor salivary gland tumors(10 benign tumors and 16 malignant tumors) during the past 7 years and analyzed their clinical characteristics. 1) The palate was the most common site of origin of minor salivary gland tumors (38.5%). 2) The most common benign tumor was pleomorphic adenoma and majority of them occur red in the palate(60.0%) and the remaining occured in the nasal cavity or the paranasal sinuses (30.0%), and the lip ( 10.0%). 3) In the case of malignant tumors the most frequent sites were the nasal cavity or the paranasal sinuses (31.3%) with the following histopathologic frequencies: adenoid cystic carcinoma(56.3%), malignant pleomorphic adenoma(12.5%), mucoepidermoid carcinoma(12.5%), polymorphic adenocarcinoma (12.5%), epthelial-myoepithelial carcinoma (6.25%). 4) Minor salivary gland tumors have high probability of malignancy and tumor extension is important to their treatment.

Purpose: To evaluate usefulness in diagnosing primary malignant lesion of metastatic bone tumor using $^{18}F$ FDG PET/CT. Material & Methods: Retrospective analysis was executed on 5,452 patients who were taken with $^{18}F$ FDG PET/CT between December 2003 and December 2007. 180 patients who had not any history of malignancy and complained musculoskeletal pain and had ill-defined osteolytic lesion in plain X-ray, were included. 96 male and 84 female were enrolled and mean age was 59.1 year old (22~90). We analyzed diagnostic accuracy, age and sex distribution of primary malignant lesion, location of metastatic lesion. Results: We could confirmed primary malignant lesion in 152 cases (84.4%). Most common malignant primary lesion was lung (28.3%), breast (18.9%) and gastrointestinal system (16.7%) and spine was the most common metastatic location of primary malignant lesion. Conclusion: $^{18}F$ FDG PET/CT is a effective molecular imaging detecting primary malignant lesion in patients having metastatic bone lesion without history of malignancy.

We report the case of a 16-year-old boy with a solid pancreatic mass which proved to be a nonfunctioning, malignant pancreatic neuroendocrine tumor (PNET). In pediatric patients, malignant pancreatic tumors are rare, especially malignant PNET. When dynamic contrast enhanced MRI showed a well enhancing solid pancreatic tumor on arterial and delayed phases and combined with malignant features, such as vascular invasion, invasion of adjascent organs, and lymphadenopathy, we should include malignant pancreatic neuroendocrine tumor in the differential diagnosis of childhood pancreatic tumors.

The present study was based on the multicenter study and retrospective method of 200 patients with intraoral minor salivary gland tumors which were received at the Yonsei university dental hospital, Soonchunhyang Bucheon hospital and Yonsei university Severance hospital from 1990 to 2006. In this study, 61.5% of the cases were benign tumor and 38.5% were malignant tumor. Of the benign tumors, pleomorphic adenoma was the most common benign tumor (n=104) and Warthin's tumor, lymphangioma, myoepithelioma and basal cell adenoma were followed. Of the malignant tumors, adenoid cystic carcinoma was the most common malignant tumor (n=32) and mucoepidermoid carcinoma, adenocarcinoma, carcinoma ex pleomorphic adenoma, metastatic adenocarcinoma and acinic cell carcinoma were followed. The most common primary tumor location was palate. The result of this study was compared with other previous reviews and showed some differences.
