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.

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.

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.

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.

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.

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.

Squamous cell carcinoma of bladder is best treated with a radical cystectomy. Squamous cell carcinoma of bladder invading the abdominal wall is not commonly reported and hard to manage surgically. Abdominal wall defect caused by a wide resection of squamous cell carcinoma invading abdominal wall can be reconstructed using various muscle flaps. We performed a salvage cystectomy for a patient with squamous cell carcinoma of bladder invading abdominal wall up to skin, and the abdominal wall defect was successfully reconstructed using a unilateral tensor fascia lata myocutaneous flap.
