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.

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.

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.

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.

Immunohistochemical studies of the molecules associated with gastric tumor progression and metastasis were done to evaluate their relationship with known prognostic factors and their usefulness in assessment of the progression of gastric carcinoma in 127 gastric carcinoma tissues. The 4 antibodies used in this study were CD44H, CD44v6, erbB-2, and p53. The CD44H expression was detected in 76 (59.8%), CD44v6 in 63 (49.6%), erbB-2 in 18 (14.2%), and mutant p53 in 98 (77.2%) out of 127 cases of gastric carcinomas. There was no significant correlation between the expression rates of each four proteins. The expression rates of all 4 proteins were not significantly correlated with age and sex of the patients and lymph node metastasis, but the correlation between CD44v6 expression and the depth of tumor invasion and tumor stage was significant (p<0.05). These results suggest that CD44v6 is closely associated with tumor invasion, and high levels of CD44H, erbB-2 and p53 are associated with tumorigenesis of the stomach as they are highly expressed in early as well as in advanced gastric carcinomas. The findings also support the conclusion that the loss of control of alternative CD44 mRNA splicing resulted in production of CD44v6 splicing variant in tumor cell facilitates tissue invasion by increased adherence of the tumor cell to an extracellular matrix or by tumor cell migration. It can be expected that CD44v6 overexpression in tumor cells appears to be an important prognostic indicator for gastric tumor progression.

Two women were referred for evaluation of new-onset urinary retention of unclear etiology. The results of the urodynamic study confirmed bladder outlet obstruction. The evaluations revealed a bladder neck mass with bilateral hydronephrosis on radiologic studies. Cystoscopy verified a urethral mass and transurethral biopsy was conducted. The pathology report showed a urethral adenocarcinoma. One patient underwent pelvic exenteration and ileal conduit, but another patient refused the operation
