Clinical analysis of 170 patients with childhood leukemia was made, who were admitted to the department of Pediatrics, Pusan Paik Hospital, Inje University, College of Medicine during 10 years from 1981 to 1990. The results were as follows: 1) The annual number of the patients with childhood leukemia was in the range of 6~25 cases. And the annual rate of the number of the patients in the department of the Pediatrics was 0.37~1.60% with the average of 1.06%. 2) Of the 170 patients, 72 cases(42.3%) were in the range of 0~5 years of age, which was the largest age group. In male, of the 97 patients, the largest age group was the age group of 0~5 years, which included 45 cases (46.4%), while in female, the largest was that of 6~10 years, which included 29 cases of 73 patients (39.8%). 3) Of the 170 patients, sex ratio was 1.33:1 with male dominance in all age groups except 1:1.6 with female dominance in the age group of 6~10 years. 4) Of the 170 patients, 113 cases were ALL (66.5%), 50 cases AML (29.4%), and 7 cases CML (4.1%). 5) In ALL, 51 cases of the 113 patients (45.1%), were in the age group of 0~5 years, 35 cases (31%) in the age group of 6~10 years, and 27 cases (23.9%) in the age group of 11~15 years. In AML, 19 cases of the 50 patients (38.0%) were in the age group of 0~5 years, 17 cases (34%) in the age group of 6~10 years, and 14 cases (28%) in the age group of 11~15 years. 6) In ALL, the sex ratio of male: female was 1.21:1, 1,50:1 in AML, and 2.5:1 in CML. 7) According to the FAB classification in ALL, of the 113 patients, 72 cases (63,7%) were in L1 type, 34 cases (30.0%) in L2 type, and only 3 cases in L3 type. In AML, of the 50 patients, 19 cases (38%) were in M2 type, 16 cases (32%) in M1 type, and 6 cases (12%) in M4 type, in order. 8) In CML, of the 7 patients, 4 cases were juvenile type, who were all under 10 years old, while 3 cases were adult type, who were all male above 11 years old. 9) Of the 170 patients, clinical symptoms on admission were pallor in 112 cases (65.9%), fever in 84 cases (49.4%), hemorrhage in 78 cases (45.9%), weakness in 40 cases (25.3%), bone pain in 32 cases (18.8%) in order. 10) Of the 170 patients, physical findings on admission were hepatomegaly in 113 cases (66.5%), lymphnode swelling in 84 cases (49.4%), splenomegaly in 78 cases (45,9%)in order. 11) Of the 170 patients, the hemoglobin level on admission were 4~7gm/dl in 95 cases (55.9%), 8~10gm/dl in 42 cases (24.7%), and 0~3gm/dl in 22 cases (12.9%) in order. 12) Of the 170 patients, the WBC count on admission were 10,000~50,000/mm3 in 58 cases (34.1%), below, 5,000/mm3 in 49 cases (28.8%), and 5,5000~100,000/mm3 in 24 cases (14.1%) in order. 13) Of the 170 patients, the platelet count on admission were below 50,000/mm3 in 93 cases (54,7%), above 100,000/mm3 in 48 cases (28.2%), 20,000~50,000/mm3 in 43 (25,3%), 43 cases (25,3%), and 50,000~100,000/mm3 in 29 cases (17.1%) in order.

Superficial angiomyxoma is a comparatively rare dermal and subcutaneous tumor. We report a case of superficial angiomyxoma of the thumb in view of its rarity and typical light and electronmicroscopic features. The patient was a 46-year-old male. who presented with an asymptomatic, slowly enlarging mass that developed in the left thumb over the 5 years. He had a history of trauma and electric burn in the same area 20~30 years ago. Simple X-ray and magnetic resonance imaging revealed 35x30mm, mass with destruction of distal phalangeal bone. On operation, the lesion was moderately well circumscribed and soft with lobulated nodules that elevated the overlying skin and destroyed the underlying bone. The cut surface of the mass was glistening and slimy. The mass was whitish gray and lobulated. Bony involvement was not present. Microscopically, the tumor was composed of stellated and spindle shaped stromal cells which were scattered throughout myxoid ground substance. Neither nuclear hyperchromasia nor plemorphisam was present. Small to medium sized thin walled blood vessels were scattered. There was a scanty infiltrate of inflammatory cells. The S-100 protein immunostaining was negative in tumor cells. On electron microscopy, the cytoplasm of the stromal cells contained well developed rough ednoplasmic reticulums and other features that indicated differentiation toward fibroblasts.

We reviewed five cases of Uterine leiomyomas, each with a conspicuously, yellow cut surface, among 198 consecutive cases of surgically removed uterine leiomyomas. Their gross findings were not significantly different from ordinary leiomyomas except for their pale to bright Yellowish cut surface. Microscopically, multiple small clusters of clear cells were widely scattered in otherwise hypercellular leiomyornas in 4 of the 5 cases. Of those, one case gave a positive reaction of Oil-Red O stain. Ultrastructurally, clear cells corresponded to the degenerating smooth muscle cells with intracytoplasmic lipid vacuoles. The rest of cells showed myofibers undergoing varying degrees of degeneration. Focal accumulation of foamy histiocytes was associated with carneous degeneration in one case. We conclude that the yellowish leiomyoma of the uterus seems, in part, to reflect accumulation of a lipid substance in degenerating hypercellular leiornyoma, or possibly collections of xanthoma cells in secondary degeneration.

Tumor DNA content measured by flow cytometry may be a predictor in the prognosis of epithelial ovarian cancer, but the results have been inconsistent. It is recognized that these conflicting results are at least partly due to the variation of DNA content between the samples from the same patient(i.e., intratumoral DNA heterogeneity). The purposes of this retrospective study were to investigate the frequency and the nature of DNA heterogeneity in epithelial ovarian cancer and to evaluate the prognostic significance of DNA heterogenetiy itself. Thirty-two patients with stage II to IV epithelial ovarian cancer who were managed at Asan Medical Center between May 1993 and April 1996 were analysed. Measurements of the nuclear DNA content were performed on samples from primary and metastatic lesion using paraffin embedded archival tissues by Epics(Coulter Inc.) flow cytometry. In two cases, the metastatic tumor was minute and did not reveal a separable peak on repeated examination. DNA heterogeneity was defined as different ploidy pattern or difference of the DNA indices than 0.15 between primary and metastatic tumors. DNA heterogeneity was found in 11 cases(36.7%), and the number of cases with homogeneous diploid and that with homogeneous aneuploid tumor were 5(16.7%) and 14(46.7%) respectively. In evaluation of prognostic significance of DNA heterogeneity using correlation with serum CA 125 level after second course of chemotherapy and residual tumor size after cytoreductive surgery among these three groups, the patients with DNA heterogeneity were considered to show intermediate prognosis between those with homogeneous diploid and homogeneous aneuploid tumor. In conclusion, DNA heterogeneity in epithelial ovarian cancer is considerable in frequency and may have prognostic value.

Epstein-Barr virus(EBV) is associated with a wide spectrum of benign and malignant disorders including leukoplakia, Hodgkin's lymphoma, central nervous system lymphoma, peripheral T cell lymphoma and nasopharyngeal undifferentiated carcinoma. There are several distinctive aspects of biology of the virus that are important in investigation of virus in clinical specimens. The abundant expression of the EBER mRNA transcripts makes possible the sensitive detection of latent expression in EBV-associated tumors. Although there has been a dramatic increased interest in the direct characterization of EBV in clinical specimens, there have been few studies about the effective and reliable positive controls in performing in situ hybridization technique for EBV, especially on paraffin-embedded tissue. We applied Burkitts lymphoma cell line as positive control in EBV in hydridization using Oncor Kit. The cell block of Burkitt lymphoma cell line(CCL85 EB-3) showed strong and specific positivity for EBER in situ in nuclei of EBV infected cells.

9.Clinical Characteristics of Xanthogranulomatous Pyelonephritis.
Korean Journal of Urology 2004;45(9):935-940
PURPOSE: In most cases, xanthogranulomatous pyelonephritis (XGP) is diffusely or focally enlarged, mimicking a neoplastic process. The purpose of this study was to improve the preoperative diagnosis of this disease. MATERIALS AND METHODS: The clinical characteristics, laboratory and radiological findings, preoperative diagnoses and operative methods of 13 patients with XGP, who underwent an operation between 1979 and 2004, were retrospectively reviewed. All patients had undergone intravenous pyelography(IVP) and ultrasonography. Their mean age was 51+/-3.3 years (range 30 to 71), with a male to female ratio of 4 to 9. RESULTS: All 13 patients had flank pain, 8(61.5%) had a urinary tract infection and 9(69.2%) with benign renal disease preoperatively underwent a simple nephrectomy. Four patients preoperatively diagnosed with a renal cell carcinoma(RCC) underwent a radical nephrectomy. 3 patients had extended to the psoas muscle. On the basis of the ultrasonographic features: (1) 6(46.1%) were diffuse hydronephrotic; (2) 4(30.8%) were diffuse parenchymal; (3) 2(15.4%) were diffuse contracted, and (4) 1(7.7%) was segmental or focal. On the basis of the computed tomography(CT) features, the diffuse or global forms(88.9%) were more common than the localized or focal forms(11.1%). Diffuse XGP may be staged as follows: Stage I(25%), involvement is limited to the kidney; Stage II(50%), involvement extends to the perirenal fat within Gerota's fascia; Stage II(25%), involvement extends beyond the Gerota's fascia into another organ. CONCLUSIONS: Preoperative diagnosis of XGP will be raised through a better understanding of the characteristics and radiological findings of this disease.

The authors performed prospectively the transcranial Doppler monitoring of bilateral anterior and middle cerebral arteries in 15 patients with ruptured cerebral aneurysm. The entry criteria for the study were confined to the patients who were admitted within 3 days after bleeding and had clinical grades of I, II, or III. The mean frequency shifts of bilateral anterior and middle cerebral arteries were increased immediately after ictus and showed continous further elevation between the 3rd and 8th rupture days. After that, they normalized slowly. The increase of frequency shift preceded clinical ischemic symptoms and an early steep increase of frequency shift was correlated to a high chance for suffering delayed ischemic deficits. The thick clots in subarachnoid cisterns shown on CT scans taken within the third rupture day were correlated well to the severe increase of frequency shifts. The aggressive treatment was done on asymptomatic patients who showed relatively rapid increase of frequency shifts, and they had shown no or trasient mild ischemic symptoms.
