Angiofollicular lymph node hyperplasia(AFLNH) was first described in 1956 by Castleman et al. It was initially reported as a solitary mediastinal mass but multicentric and extranodal disease is now well known. Histologically two distinct variants, e.g. the hyaline vascular type and the plasma cell type, of AFLNH are recognized. And the plasma cell type is typically associated with clinical syndrome consisting of fever, anemia, elevated erythrocyte sedimentation rate and polyclonal hypergammaglobulinemia. Recently, we experineced three cases of AFLNH. Histologically, two cases were hyaline vascular type, that were presented as a right supraclavicular mass of 49-year-old female, and as an anterior mediastinal mass of 53-year-old female. The remaining one case was plasma cell type that was presented as a left axillary mass of 63-year-old male. The former two cases showed typical features of hyaline vascular type but in case 1, exuberant proliferation of hyalinized vessels of capillary size was characteristic feature. The latter case of plasma cell type characteristically showed clinical syndrome consisting of fever, hypoalbuminemia, polyclonal hypergammaglobulinemia. All cases were presented as a single mass and they were well after surgical excision.

Malignant mixed miillerian tumor (MMMT) was one of the rare uterine sarcoma. This tumor is composed of sarcoma and carcinoma. Primary MMMT in the peritoneum is among the rarest sites for MMMT. MMMT is highly malignant and the prognosis is grave due to frequent recurrence and metastasis. In the world literature, only 22 cases with primary MMMT of the peritoneum have been reported and most of these were single report. We report one case of primary MMMT in the peritoneum with a brief review.

PURPOSE: To report the technical effectiveness, outcome, and incidence of complications of combined clear cornea phacoemulsification with intraocular lens implantation and pars plana vitrectomy. METHODS: Single-center prospective, non-comparative, consecutive case series. Twenty-three eyes of 23 patients underwent combined clear cornea phacoemulsification and pars plana vitrectomy for various vitreoretinal disorders due to cataracts by a single surgeon between July 2003 and August 2004. Surgical feasibility, intraoperative and postoperative complications and outcome of clear cornea incisions in all combined procedure were evaluated. RESULTS: No significant adverse effect of clear corneal wound on pars plana vitrectomy procedures was noted in any of the patients. Operatively and postoperatively, no significant complications related to clear corneal wound were noted, even with the variations of pars plana vitrectomy procedures for cases with and without gas-fluid exchange and intravitreal tamponade. CONCLUSIONS: Clear corneal incisions is a safe and more reasonable alternative in combined phacoemulsification with intraocular lens implantation and pars plana vitrectomy. For a more comprehensive conclusion, a comparative study with scleral tunnel incisions may be necessary.

PURPOSE: Spontaneous subarachnoid hemorrhage(S-SAH) is a relatively rare disease with good clinical course and prognosis. The purpose of this study is to evaluate the cisternal blood distribution on CT in patient with S-SAH. MATERIALS AND METHODS: Out of 406 patients with subarachnoid hemorrhage on brain CT scan, 11 patients confirmed to be S-SAH by angiography and clinical follow-up were examined. We analysed the CT findings of these 11 cases retrospectively. RESULTS: Five patients had only perimesencephalic distribution of hemorrhage:the prepontine, the interped- uncular, and the suprasellar cisterns were involved in 4 cases each, the basal sylvian cistern in 3 cases, and the ambient cistern in 2 cases. The quadrigeminal and a portion of the lateral sylvians were also involved in 1 case each. Six patients revealed cisternal hemorrhage extending beyond the perimesencephalic cistern into the ventricles, cortical sulci, and lateral sylvian fissure. Intraventricular hemorrhage was noted in 3 cases of these 6 patients. CONCLUSION: Our study suggests that uncomplicated clinical course and normal anglographic finding are more important than CT distribution of cisternal hemorrhage in diagnosing S-SAH.

PURPOSE: The purpose of our study is to evaluate characteristic features of 4th ventricular tumors in CT and MRI. MATERIALS AND METHODS: Pathologically proved 9 patients with 4th ventricular tumor were examined by CT and/or MRI. 4th ventricular tumors were epedymoma(4 cases), medulloblastoma(2 cases), choroid plexus papilIoma(2 cases), and oligodendroglioma(1 case). Included in our study were only those mass lesions that were located at surgery predominently within 4th ventricle with or without ventricular expansion. RESULTS: The origin of 4th ventricular tumor was the roof (epedymoma 3 cases, medulloblastoma 2 cases), the floor (epedymoma 1 case), and the undetermined(remaining 3 cases). On MRI, all tumors were hypointense exept ependymoma(3 cases) showing isointensity on T1WI. All tumors were hyperintense on PDWI and T2WI. On Gd-DTPA enhanced T1WI, strong enhancement was seen in all but epedymoma(1 case) which showed mild enhancement. On CT, as compared with MR images, various density on precontrast and postcontrast images were seen. Calcification was seen in choroid plexus papilloma(1 case) and oligodendroglioma(1 case). Hydrocephalus is seen in all cases exept ependymoma(2 cases) and oligodendroglioma(1 case). Hemorrhage within tumor was present only in epedymoma(2 cases). Cystic change or necrosis of tumor was seen in ependymomma(3 cases), choroid plexus papilloma(1 case), and oligodendroglioma(1 case). Peritumoral edema was seen in medulloblastoma(1 case). Extension through the foramen Luschka and the Magendie was seen in ependymoma(2 cases), choroid plexus papilloma(2 cases), and medulloblastoma(1 case). Seeding along the CSF pathway was seen only in ependymoma(2 cases). CONCLUSION: The results of our study may suggest that specific diagnosis of 4th ventricular tumor can be suggested preoperatively by analysing the origin in 4th ventricle, difference of CT density or MRI signal inten. sity, presence of extension or seeding through cerebrospinal fluid of the lesion.

OBJECTIVE: Although marker chromosome is defined as an abnormal chromosome in which no part can be identified, derivative chromosomes with structural abnormalities of unknown origin are also called as marker chromosomes conventionally. The clinical significance of a marker chromosome is determined according to the origin of marker chromosome. In this study reverse painting fluorescence in situ hybridization (FISH), and comparative genomic hybridization (CGH) methods were employed to elucidate the origin of marker chromosomes in 5 clinical cases. METHODS: Reverse painting probes were generated from five copies of each marker chromosomes microdissected with micromanipulator, amplified with DOP-PCR, and labeled with fluorochromes. The probes were hybridized to normal metaphases. For CGH, normal control and patients' DNA were directly labeled with spectrum-red-dUTP and spectrum-green-dUTP by CGH nick translation kit, and hybridized to normal reference metaphases. The CGH images were captured with a computer controlled fluorescence microscope equipped with a CCD camera and analyzed by Cytovision workstation. RESULTS: Five marker chromosomes were identified as follows (1) derivative chromosome 15 inducing partial trisomy of 15pter->q21, (2) isochromosome of 18p causing 18p tetrasomy, (3) short arm of chromosome 5 causing 5p trisomy (4) small accessory chromosome originated from centromeric region of chromosome Xq11->q12 (5) der(17) with inverted duplication of the short arm of chromosome 17. In all cases the origin of each marker chromosomes were identified successfully with reverse painting FISH, and these results were concordant with the CGH profiles. CONCLUSION: Our results indicate that combined reverse painting FISH and CGH is a rapid, convinient and powerful tool to identify the origin of marker chromosomes and derivative chromosomes caused by various chromosome abnormalities such as translocation, duplication, deletion.

PURPOSE: To evaluate the effects of X-irradiation on prenatal deaths, i.e., preimplantation deaths, embryonic deaths, and fetal deaths, and on external malformations in precompacted preimplantation ddy mice. MATERIALS AND METHODS: Pregnant mice (n=85), obtained by limiting the mating time to from 6 to 9 A.M., were segregated into 11 groups. The first five groups (n=26) were irradiated with X-ray doses of 0.1, 0.5, 0.75, 1.5, and 3 Gy, respectively, at 24 h post conception (p.c.) of the preimplantation period. The second five (n=27) groups were irradiated at the same X-ray doses, respectively, but at 48 h p.c. of the preimplantation period. The last group (n=32) was the control group. The uterine contents were examined on the 18th day of gestation for prenatal deaths and external malformations. RESULTS: 1) A statistically significant increase in preimplantation deaths with increasing dose was observed in the experimental groups irradiated at 24 h p.c. and in the groups irradiated at 48 h p.c., as compared to the control group. The threshold dose was close to 0.05 Gy and 0.075 Gy for the irradiations at 24 h p.c. and 48 h p.c. respectively.2) A statistically significant increase in embryonic deaths with increasing dose was observed in all irradiation groups, except the group irradiated with a dose of 0.1 Gy at 48 h p.c..3) No fetal deaths were found in any experimental group.4) In the experimental groups irradiated at 24 h p.c., anomalies increased with statistical significance, as compared with the control group: 2 exencephalies, 2 open eyelids, 3 anophthalmias, 2 cleft palates, 2 gastroschisis, 1abdominal wall defect, 1 leg defect, and 2 short tail anomalies; the threshold dose for external malformations was close to 0.2 Gy at 24 h p.c.. In the groups irradiated at 48 h p.c., 1 open eyelid and 2 short tail anomalies were observed, but there was no statistical significance in those malformations. CONCLUSION: The results of this study reveal that X-irradiation of precompacted preimplantation ddy mice causes not only preimplantation deaths and embryonic deaths but also external malformations. In addition, external malformations were observed in our experiments at diagnostic doses, including 0.1 and 0.5 Gy. For this reason, we recommend that irradiation should be avoided during the preimplantation period by applying Rugh's 10-day rule.
