Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

INTRODUCTION: This study was performed to evaluate the diagnostic usefulness of simultaneous determination of 3 tumor markers {serum carcinoembryonic antigen(CEA), squamous cell carcinoma antigen (SCC Ag) and neuron specific enolase(NSE)} in lung cancer patients. METHOD: In 113 patients with primary lung cancer(70 with squamous cell carcinoma, 30 with adenocarcinoma, 13 with small cell carcinoma) and 103 patients with benign lung diseases, serum CEA and NSE were measured by enzyme immunoassay, and SCC Ag was measured by microparticle enzyme immunoassay. RESULTS: 1) The mean serum levels of 3 tumor markers were significantly higher in lung cancer groups than benign lung disease groups respectively(p=0.001). 2) In squamous cell carcinoma, the SCC Ag was elevated in 67%, in adenocarcinoma CEA was elevated in 77% and in small cell carcinoma NSE was elevated in 77%, but there were no significant differences according to the stage of each cancer cell types. 3) CEA was the most sensitive marker, but nonspecific to cancer types. SCC Ag was less sensitive than other markers, but more specific toward squamous cell carcinoma, and NSE was more specific to primary lung cancer. 4) As the number of positive tumor markers was increased, the relative possibility of lung cancer was also increased. If two markers were positive, it increased to 77%, and if three markers were positive it increased to 90%. CONCLUSION: The simultaneous measurement of serum CEA, SCC Ag and NSE would provide additional information for the diagnosis of lung cancer.

BACKGROUND: A stenosis of left main coronary artery has critical prognostic importance. Recent reports on successful left main stenting are now challenging traditional treatment patterns for this lesion. We evaluated recent four-year trends in incidence, clinical, angiographic findings and treatment modalities in patients with left main coronary artery stenosis(LMS). METHODS: Patients who were diagnosed as a significant LMS at Yonsei cardiovascular hospital between 1996 and 1999 were analyzed retrospectively. RESULTS: The incidence of LMS during the period of 1996 to 1999 was 3.3%(n=24) and it was significantly higher than that of previous 15 years before 1996(p<0.01). The incidence of isolated ostial lesion was 0.28% and this lesion was more prevalent in young female patients with less risk factors compared with other types of LMS(p<0.01). After exclusion of the patients with an isolated ostial lesion, patients were grouped according to the lesion site: ostium, shaft, and shaft lesion extended to distal vessels. There were no differences in clinical and hemodynamic findings among these groups. Coronary artery bypass graft was performed in 141 patients(63%) and stent implantation in 16 patients(14%). CONCLUSION: The incidence of LMS has been increased. There was no difference in clinical and hemodynamic findings according to the types of LMS. Surgery is still a standard treatment, but in selected patients percutaneous coronary intervention can be another treatment option.

A case of extrapulmonary silicosis involving abdominal lymph nodes in a 62-year-old man is presented. The patient underwent subtotal gastrectomy and regional lymph nodes dissection for gastric adenocarcinoma of clinical stage III. On gross examination, two separate gastric adenocarcinomas and multiple enlarged lymph nodes mimicking metastatic lesion were noted. Microscopic examination of the enlaged lymph nodes revealed characteristic sclerohyaline silicotic nodules without metastatic adenocarcinoma. Chest roentgenogram showed diffusely scattered multiple tiny nodular lesions in the entire lung fields, particularly the posterior side of both upper lung fields. He had worked in a mine for 18 years and had been exposed to silica for 5 of those years. We report incidentally found, unusual case of extrapulmonary silicosis.

The pulmonary sarcomatoid carcinoma is a rare malignant tumor, which is composed of an admixture of carcinomatous and sarcomatous components, and accounts for 0.3% of all pulmonary neoplasms. Clinicopathological features are often related to anatomical location: central endobronchial type and peripheral parenchymal type. Noninvasive diagnostic test had a low yield in detection sarcomatoid carcinoma. Metastasis to the regional lymph nodes and to distant organ is common. The prognosis is poor and the median survival is about 15 months. We report two cases of pulmonary sarcomatoid carcinoma with review of literatures.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.
