The authors report a case of malignant teratoma in a 3-year-old girl who suffered from occipital headache and vomiting for about 2 months. The tumor occupied left cerebellopontine angle resulting in a moderate degree of hydorcephalus. Histologically, the tumor consisted mainly of neuroepithelial tissues showing varying degrees of differentiation, with areas of epidermis, mature fat tissue, connective tissue, gastrointestinal glands and smooth muscle bundles containing ganglions. Also noted are groups pf polygonal or spindle cells representing immature mesodermal tissue. In contrast to two malignant intracranial teratomas previously reported in Korean literatures, this case is characterized by the presence of predominent neuroepithelial components and by uncommon tumor location, the posterior fossa far from middle line of the body.

Adenocarcionma of fetal type is in lung is a newly recognized malignant tumor sharing morphologic features with the epithelial component of the pulmonary blastoma devoid of sarcomatous component. We present a case of adenocarcinoma of fetal type in a 28-year-old female, consisting of numerous branching tubules or glands and morula-like epithelial complexes. Histologically, the tubules and glands were composed of glycogne-rich nonciliated epithelial cells showing in part argyrophilia. Some of tubular and morula-like epithelial cells revealed immunoreactivity for neuron-specific enolase. We report this case with a review of literatures with special references on the histogenisis. This report is the pathologically confirmed second case of the pulmonary adenocarcinoma of fetal type in Korea, following the report of Cho and Lee, 1990.

There are two major types of vascular birthmarks, hemangiomas, those demonstrating endothelial hyperplasia, and malformation, those with normal endothelial turnover. Venous malformations have previously been treated by surgical excision, where possible. Although not a panacea for all such tumors, the use of sclerosing agents is decidedly preferable in some cases to extirpation with a scapel. The method involves the direct injection of absolute alcohol into the lesion on the fluoroscopic guide. The effect of treatment is satisfactory and there appears tobe no long term complication. We report 2 cases of surgically irresectable and deep-seated venous malformation which were treated sclerotherapy using ethanol.

The present study was performed to evaluate histomorphological difference in various surface-treated implants in beagle. Implants(Implantium(R), Dentium Co. Korea) with pure titanium machined surface, acid treated surface, and Al2O3(50~100micrometer)blasted with acid treated surface were used in this study. All mandibular premolars of 1.5~2 year old male beagle dogs were extracted. At 3 months after extraction, the implants(phi 4mm, l6mm) were installed. The beagle were sacrificed at 1, 3 months after installation and then tissues including implants were prepared for non-decalcified specimens. These specimens were analyzed comparatively under light microscope. The results of this study were as follow 1. Higher rate of osseointegration were showed in the Al2O3(50~100micrometer)blasted with acid-treated surface. 2. Increased osseointegration were showed in the Al2O3(50~100micrometer)blasted with acidtreated surface with time. 3. Higher maturation of integration were showed in the Al2O3(50~100micrometer)blasted with acid-treated surface. In conclusion, surface treatment of Al2O3blasted with acid might be considered to shorten healing time and improve success rate as increasing contact of implant and bone.

PURPOSE: The aim of this study was to estimate the current prevalence of varicocele and their effect on the testicular volume. MATERIALS AND METHODS: The relationship between testicular volume and the degree of varicocele, as classified by Dubin-Amelar, was evaluated in 1,281 Korean school boys, between 15 and 18 years of age. All examinations were carried out by a single urologist, and the testicular volume was measured in the upright posture using a Prader's orchidometer. All the boys were assessed for their previous medical history, family history. RESULTS: There was a 12.9% prevalence of varicocele in the adolescents. The mean testicular volume in the control groups was 14.29+/-2.10ml on the left and 14.45+/-2.13ml on the right. Patients with left varicocele had a testicular volume of 13.09+/-2.34ml on the left and 13.24+/-2.32ml on the right. The testicular volume of patients with a grade I varicocele were similar to those in the control group. Patients with grade II and III varicoceles had significantly smaller testes than the control groups. CONCLUSIONS: The reduction in testicular volume due to a varicocele correlated with the severity of the varicocele grade. Careful evaluation for testicular volume loss, and early surgical intervention, should be offered to adolescent patients with varicoceles.
