Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

PURPOSE: The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS: The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10degrees of mesial angulation to the center analog. Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Eventually, 40 experimental casts were produced. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. The analysis of variance was performed using the SPSS (v 12.0) program (alpha = .05), and the statistical significance was set at P < .05. RESULTS: The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. However, no significant difference was observed with respect to the length of the impression coping. Additionally, no significant difference was observed between the parallel and mesial angulated groups. CONCLUSION: Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. Additionally, the accuracy of the implant cast was not different for the parallel and 10degrees mesial angulated groups.

Cystitis glandularis is a benign metaplastic proliferative lesion of the urinary bladder which usually occurs in the setting of chronic irritation and infection or in some cases as a congenital process. Sometimes it presents as a tumor mass-like florid lesion, grossly mimicking malignancy. We report a case of 59-year-old man with multiple mass lesions around the trigone and the neck portion, which suggested the possibility of malignancy in clinical and radiological evaluations. Final diagnosis was confirmed by transurethral resection. The surface urothelial lining was intact. The submucosa showed von Brunn's nests, cystitis glandularis and cystitis cystica in the edematous lamina propria. There were numerous glands lined by tall columnar, mucin producing epithelium without atypia, conforming to the appearance of the intestinal variant of cystitis glandularis. The cystitis glandularis may mimic a neoplasm on gross evaluation. The intestinal variant of cystitis glandularis is particularly likely to be problematic when florid.

Dermoid cysts can be found anywhere in the body, particularly in areas where embryonic elements fuse together. Dermoid cysts arising in the head and neck lesion are relatively common, but that of nasolabial area has not been reported. Recently, we experienced a case of epidermoid cyst mimicking nasolabial cyst. The patient was a 49 year-old man with an anterior nasolabial swelling that has been presented for 1 year. After cyst excision, a histologic examination revealed that it was an epidermoid cyst. We report this case with the literature review.

Tuberculosis of the pancreas is a very rare disorder, little reported in the literature. Several theories of the pathogenesis of pancreatic tuberculosis have been proposed. Direct invasion of the pancreas by Mycobacterium tuberculosis is rare; most commonly the pancreas is spared even when liver and spleen are severely involved by miliary dissemination. More common is the involvement of abdominal lymph nodes which, as caseating masses, subsequently invade the pancreas. Pancreatic tuberculosis is a treatable and preventable disease; however, major challenges remain in diagnosis. There have been several reports including the endoscopic retrograde pancreatographic(ERP) findings, however, our case of pancreatic tuberculosis showed quite unusual ERP findings. We report a 54-year old man suffering from chronic epigastric pain and weight loss who was diagnosed intraabdominal tuberculosis with pancreatic involvement. Abdominal ultrasonography showed ill-defined hypoechoic mass at pancreatic head, peripancreatic lymph nodes enlargement and intra- and extrahepatic bile ducts dilatations. Endoscopic retrograde pancreatogram showed blurring and irregularity of the second branch of pancreatic duct at head and the parenchymal abnormal pooling of the contrast dye was noted. Percutanieous transhepatic cholangiogram revealed the complete obstruction of the distal common bile duct. At explo-laparotomy, massive necrosis and fibrous adhesions were noticed around the extrahepatic bile duct and pancreas head and multiple pericholedochal lymph nodes enlargement and several whitish-yellow nodules on the surface of the liver were noted. The extrahepatic bile duct was dilated and the common bile duct at the suprapancreatic portion was compressed by the lymph nodes and necro-inflammatory tissues which invaded the pancreatic head posteriorly. The microscopic findings of the nodules on liver surface and lymph nodes revealed the typical findings of the tuberculosis.

To evaluate the clinical significance of anomalous pancreaticobiliary ductal union(PBDU), we analysed 11 cases(0.19%) of anomalous PBDU among 5675 cases performed ERCP from Jan. 1973 to Aug. 1992. According to the classification of Kimura et al., 4 cases were type 1(P-C union) and 7 cases type 2(C-P union). The length of common channel ranged from 1.5 cm to 3.1 cm(mean 1.9 cm). The common associated disease were choledochal cyst(7 cases), carcinoma of the gallbladder(5 cases) and biliary stone(3 cases). Four cases of carcinoma of the gallbladder were type 1. The incidence of anomalous PBDU was significantly higher in cases with carcinoma of the gallbladder(5 cases among 49 cases) than in case without carcinoma of the gallbladder(6 cases among 5626 cases). And the incidence of gallbladder carcinoma(45%) among the 11 cases of anomalous PBDU was significantly higher than that(0.78%) among those who did not have anomalous PBDU. In conclusion, the common associated diseases with the anomalous PBDU were choledochal cyst, carcinoma of the gallbladder and stone, and the anomalous PBDU may be risk factor in the development of carcinoma of the gllbladder.

PURPOSE: Because previous studies have reported depleted antioxidant capacity in patients with chronic pancreatitis (CP), prevention of free radical production has gained importance in antifibrotic treatment strategies for CP. The aim of this study was to investigate the effects of ascorbic acid on oxidative capacity and pancreatic damage in experimental CP. MATERIALS AND METHODS: CP was induced in male Sprague-Dawley rats by infusion of dibutyltin dichloride (DBTC) into the tail vein. Ascorbic acid was given intraperitoneally at a daily dose of 10mg/kg body weight. The treatment groups were as follows: group 1, DBTC plus intraperitoneal physiologic saline; group 2, DBTC plus intraperitoneal ascorbic acid; group 3, solvent plus intraperitoneal physiologic saline; group 4, no operation plus intraperitoneal physiologic saline. Each group contained 15 animals. Treatment was started after CP was established. After 4 weeks of treatment, serum hyaluronic acid and laminin levels were determined by radioimmunoassay, pancreatic tissue oxidative stress was analyzed, and the degree of pancreatic damage was determined. RESULTS: Ascorbic acid treatment markedly increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) concentrations in pancreatic tissue (p < 0.01 for both). Significant serum hyaluronic acid and laminin reductions were observed in group 2 as compared with group 1 (p < 0.05). However, the serum hyaluronic acid and laminin levels remained elevated when compared with those of groups 3 and 4 (p < 0.05). Histopathologic scores were also lower in animals with CP that underwent ascorbic acid-treatment (p < 0.05). CONCLUSION: Ascorbic acid treatment alleviated the degree of oxidative stress and pancreatic damage in rat CP. Antioxidant treatment might be considered a potential option to improve the pathologic process in CP.
