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.

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.

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.

PURPOSE: There diagnostic modalities have been commonly used to detect prostate cancer to date: digital rectal examination (DRE), serum prostate specific antigen (PSA) and transrectal ultrasonography(TRUS). We evaluated the diagnostic values of these three modalities in the early detection of prostate cancer. MATERIALS AND METHODS: We analysed 215 patients with low urinary tract symptoms who had pathologic diagnosis for prostatic cancer was possible by biopsy or transurethral resection. Transectal ultrasonography guided sextant biopsies were performed if the PSA level was greater than 4.0 ng/ml or DRE was suspicious, even if TRUS revealed no ateas suspicious for cancer. TURP were performed without TRUS or biopsies if the PSA level was lesser than 4.0 ng/ml and DRE was negative. RESULTS: Of the 215 patients, 36 (16.7%) revealed prostate cancer. Positive predictive value, sensitivity and specificity was 37.0%. 83.3%. 71.5% for DRE, 30.0%, 91.7%, 58.3% for PSA and 27.6% 58.3%. 43.3% for TRUS respectively. Positive findings on serum PSA or DRE or both tests detected significantly more tumors(97.2%, 35of 36 cancers) than only PSA (91.7%, 33 for 36 cancers), DRE (83.3%, 30 of 36 cancers) and TRUS (60.0%, 21 of 35 cancers) alone. CONCLUSIONS: These result shows that DRE is more valuable and cost effective method for detection of prostate cancer than serum PSA and the use of DRE in conjunction with serum PSA enhances prostate cancer detection.

PURPOSE: We compared the recurrence rate and mean interval to recurrence according to tumor grade after complete transurethral resection and adjuvant intravesical instillation with bacillus Calmette-Guerin (BCG), in patients with stage T1 transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Between January 1994 and May 2000, 31 patients presenting to our hospital with T1 superficial bladder cancer received adjuvant intravesical instillation with BCG after complete transurethral resection of the bladder tumor. Tumors with CIS lesion or recurrent tumors were excluded. The recurrence rates, mean interval to recurrence, tumor size and number of tumors were compared according to tumor grade. RESULTS: Of the 31 patients, 5 presented with grade I tumor, 17 with grade II tumor and 9 with grade III tumor. Mean follow-up period was 22 months (range 6-58) and mean tumor sizes according to tumor grade were 1.6, 1.6 and 1.7cm in grade I, II and III, respectively. Twelve (38.7%) patients experienced tumor recurrence. The recurrence rates according to tumor grade were 20.0%, 41.2% and 44.4% in grade I, II and III, respectively. Mean interval to recurrence were 40, 11.4 and 7.5 months, respectively. CONCLUSIONS: Our results suggest that the recurrence rates were higher in grade II and III tumors than in grade I tumor. Therefore close follow-up is necessary in both grade II and III tumors.
