A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Calcification is found in 4% to 12% of renal masses due to a number of causes and can be seen in various patterns. This is found in 1% to 3% of the simple renal cysts. Among these a peripheral egg-shell type of calcification is more rare. We experienced the simple renal cyst associated with the thick egg-shell calcification on the renal upper pole in a 66-year-old female complaining upper abdominal discomfort, so we report that with literature.

We described the clinical manifestation of herpes zoster in thirteen children with underlying malignancies. Among the associated malignancies, hematologic malignancy including acute lymphotytic leukemia was the commonest and CNS tumors were also frequently associated. Pain was mild, and some showed high fever and abnormal liver function test results. Recurrent attacks were observed in 3 cases(23%). Thoracic segment and trigeminal nerve were commonly affected. In most cases, herpes zoster developed within two years after the diagnosis of the malignancy.

Background/Aims: Extracellular vesicles (EVs) are secreted from various types of cells and have specific functions related to their origin. EVs are observed in the small intestinal lamina propria (lpEVs), but their function remains unclear. This study aimed to investigate the role of lpEVs. Methods: LpEVs were isolated from antigen (ovalbumin [OVA])-fed mice (lpEVs/OVA), and administrated to the naïve mice for 5 days before induction of lung inflammation. Afterwards, the mice were sensitized and challenged with OVA to evaluate the role of lpEVs/OVA in the regulation of immune tolerance. Results: The isolated lpEVs/OVA were sphere-shaped, bi-layered vesicles of approximately 50 to 100 nm in size. The vesicles expressed CD81, A33 antigen, and major histocompatibility complex (MHC) class II on the surface. When administrated to naïve mice, the lpEVs/OVA migrated to the spleen. Intraperitoneal lpEVs/OVA administration to naïve mice decreased the immune response against sensitized antigen in a CD4+FoxP3+T cell-dependent manner. Conclusions EVs are actively secreted from small intestinal epithelial cells to deliver information about orally administered antigens to immune cells, which will facilitate the modulation of the immune response by acting as an intercellular communicasome.

PURPOSE: The purpose of the study is to compare the outcomes between three different one-layer vasovasostomy techniques: original one-layer, modified one-layer, and V-V type one-layer microsurgical vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed the charts and surgical records of all surgical procedures performed on a series of 117 consecutive patients undergoing a microsurgical one-layer, modified one-layer or V-V type one-layer vasovasostomy between May 1995 and March 2000. An original one-layer vasovasostomy was used in 48 men (group 1), a modified one-layer vasovasostomy in 35 men (group 2), and V-V type one-layer vasovasostomy in 34 men (group 3). A successful outcome (patency) was defined as sperm presenting at the follow-ups. RESULTS: The sperm concentration (million/ml) and motility (%) were as follows: in original one-layer vasovasostomy 17.5 and 32.9, in modified one-layer vasovasostomy 26.1 and 28.5 and in V-V type vasovasostomy 30.5 and 32.3. There were no significant differences in patency (85.4%, 91.4% and 91.2%) and pregnancy rate (56%, 62.5% and 63.6%) of the procedures. If the obstructive interval had been less than 4 years, patency was 87.5% and pregnancy rate was 61.5%, 5 to 9 years 95.8% and 63.4% and 10 years or more 83% and 58.3%. There were no correlations between obstructive interval and rates of patency and pregnancy. CONCLUSIONS: The patency and pregnancy rate revealed slightly better result in modified one-layer or V-V type one-layer microsurgical vasovasostomy than in original one-layer microsurgical vasovasostomy. However, they had statistically no significant differences in overall.

PURPOSE: To evaluate the enhancing pattern of gastric carcinomas at dynamic incremental CT and to correlate it with pathologic findings. MATERIALS AND METHODS: We retrospectively evaluated the enhancement pattern of stomach cancer on dynamic incremental CT of the 78 patients. All the lesions had been pathologically proved aftersurgery. The enhancement pattern was categorized as good or poor in the early phase ; homogeneous, heterogeneous or ring enhancement ; the presence or absence of delayed enhancement. There were 16 cases of early gastriccancer(EGC), and 62 cases of advanced gastric cancer(AGC). The Borrmann type of AGC were 1(n=1), 2(n=20), 3(n=32),4(n=8) and 5(n=1). The histologic patterns of AGC were tubular(n=49), signet ring cell(n=10), and mucinous(n=3). The enhancing patterns were compared with gross and histologic findings and delayed enhancement was corrrelated with pathologic evidence of desmoplasia. RESULTS: Good enhancement of tumor was seen in 24/41cases (58.5%) with AGC Borrmann type 3-5, in 6/21(28.6%) with AGC Borrmann type 1-2, and in 3/16(18.8%) with EGC (P<.05). By histologic pattern, good enhancement of tumor was seen in 8/10(80%) with signet ring cell type, in 21/49(42.9%)with tubular type, and in 1/3(33.3%) with mucinous type(P<.05). EGC was homogeneously enhanced in 14/16cases(87.5%), but AGC was heterogeneously enhanced in 33/62(53.2%), respectively(P<.01). There was no significant correlation between delayed enhancement and the presence of desmoplasia. CONCLUSION: AGC Borrmann type 3-5 andsignet ring cell type have a tendency to show good enhancement and EGC is more homogeneously enhanced at dynamicincremental CT.

Duane's retraction syndrome is a deficiency in abduction and a defect in abduction movements, with retraction and narrowing of the palpebral fissure of the affected eye. In addition, there are often an upshoot or downshoot of the affected eye on attempted abduction, widening of the palpebral fissure with abduction and mild to marked defect in convergence. But, the clinical picture in Duane's retraction syndrome is extremely variable. Two cases of Duane's retraction syndrome are presented, each of them is Duane's type I and type III, which are affected on left eye. The literatures relating to this syndrome are briefly reviewed.

Leiomyoma is a benign tumor, which usually occur at the smooth muscle of the gastrointestinal tract and uterus but rarely occurs on the corpus cavernosum of the penis. We experienced a patient with leiomyomas on the bilateral corpus cavernosa of the penis accompanied with impotence in a 60-year-old man. The patient was treated with complete local excision and has remained well without recurrence for l year, So we report this case with review of literatures.
