Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

OBJECTIVES: The aim of this study is to verify the status and the clinical significance of BRAF and NRAS mutations in patients of one of the university hospitals in Korea. METHODS: Polymerase chain reaction (PCR) amplification and direct sequencing were performed for the analysis of melanoma samples (n=22) for the detection of mutations in exon 15 of the BRAF gene, and exons 2 and 3 of the NRAS gene in genomic DNA. Mutations of the BRAF gene were correlated with the clinicopathologic features of patients and the BRAF mutation status was compared in 18 paired primary and metastatic tumors. RESULTS: Incidence of somatic mutations within the BRAF and NRAS genes was 27.3% (6/22) and 0% (0/22), respectively. Age, gender, Breslow thickness, and ulceration did not show correlation with BRAF mutations. Among 18 patients with metastasis, BRAF mutation was detected in 22.2% of cases (4/18), and all four cases with BRAF mutations were identified in metastatic lymph node tissues. BRAF mutations were only found in lymph node metastases, which was statistically significant (28.6% vs 0%, P<0.01). CONCLUSION: The incidence of BRAF mutation is as low as in other Asian reports and the NRAS mutation was not found in patients of our institute.

A case of malignant eccrine acrospiroma of the anterior chest wall is reported. This mass had been present for 20 years and during rescent 5 years it showed frequent ulceration and bleeding suggesting malignant transformation. Microscopically, several foci malignant transformation from preexisting benign eccrine acrospiroma are seen and in immunohistochemical staining, the tumor cells both benign and malignant portion, show positive reaction to cytokeratin.

OBJECTIVE: Immediate contralateral epidural hematoma (EDH) and traumatic intracerebral hematoma (T-ICH) after craniectomy for traumatic subdural hematoma (SDH) are rare but devastating post-operative complications. Their clinical features and outcomes are not well studied. In this report, we present the clinical features and outcomes of immediate contralateral acute hematoma cases requiring a second operation. METHODS: This study includes 10 cases of immediate contralateral EDH and T-ICH following bilateral craniectomy for the evacuation of traumatic SDH and contralateral hematoma between 2004 and 2015. Their medical records and radiographic findings were reviewed and analyzed retrospectively. RESULTS: Ten of the 528 patients (1.89%) who underwent craniectomy for the evacuation of traumatic SDH developed post-operative EDH (n=5), T-ICH (n=5). The trauma was caused by a fall in 5 patients and by a traffic accident in 5 patients. The patients who suffered trauma due to pedestrian accidents died. Seven patients had a low admission Glasgow Coma Scale (GCS; GCS≤8) score in the preoperative state (average admission GCS, 7.7; average discharge GCS, 3.4; and average discharge Glasgow Outcome Scale, 2.0). Severe intra-operative brain swelling was noted in all patients, while skull fracture was observed in 8. Multiple associated injuries and medication for heart disease were characteristic of patients who died. CONCLUSION: The prognosis of delayed contralateral hematoma was very poor. Multiple associated injuries, past medical history and traffic accidents, especially pedestrians were seemed to be associated with higher mortality rates. Finally, contralateral skull fractures can indicate high risk of delayed contralateral acute intracranial hematoma.

V. parahaemolyticus was isolated from blood culture of a 34-year old female patient with HCV viral hepatitis and liver cirrhosis. V. parahaemolyticus is one of the frequent causative agents of gastrointestinal infection, but rarely causes septicemia. This case is thought to be the 3rd report of V. parahaemolyticus septicemia in Korea.

Until now, surgical treatment of bile duct carcinoma has been unsatisfactory. There have been few reports dealing with the clinical significance of epidermal growth factor receptor(EGFR) and c-erbB-2 in bile duct cancer. To evaluate epidermal growth factor receptor(EGFR) and c-erbB-2 protein as a marker for prognosis, we analyzed the data and outcome of 32 cases of extrahepatic bile duct carcinoma immunohistologically, as well as clinicopathologically. The expressions of EGFR and c-erbB-2 showed in 71.9%(23/32) and 34.4%(11/32), respectively. The expression of EGFR was closely associated with the expression of c-erbB-2 (p<0.05). The expression rate of EGFR was significantly higher in well-differentiated cancer than in poorly-differentiated cancer (p<0.05), but was not related to stage, or lymph node metastasis. The expression of c-erbB-2 was not related to stage, lymph node metastasis, and differentiation. The expressions of EGFR and c-erbB-2 did not correlate with survival. In conclusion, the expression of EGFR or c-erbB-2 may be used as a tumor marker, but not as a prognostic factor in extrahepatic bile duct cancer.

A 62-year-old male with a smoking history of 30 pack-years presented with a 1-year history of a periumbilical pulsating mass. He had been treated for hypertension for 2 years. Physical examination revealed a huge pulsating mass in the periumbilical abdomen. Femoral and popliteal arterial pulses were palpable. Computed tomography showed arterial dissection in the proximal segment of the superior mesenteric artery, a huge aneurysm (52×50 mm) with mural thrombus and two smaller aneurysms (20×20 mm) in the right ileocolic and ileal branches, along with atherosclerotic changes. Interposition using the great saphenous vein was performed after aneurysmal isolation and ligation of jejunal branches in the sac. Distal flow was reestablished by end-to-end and end-to-side anastomoses of the right ileocolic and ileal branches, respectively. No complications were observed at 1-year follow-up.

Recently the use of hydrochloric acid as a toilet disinfectant has become more common, and the risk of its ingestion is though to be increasing. We experienced a case of 67 year-old man who accidentally ingested hydrochloric acid and as a result developed a postprandial epigastric fullness end pain 3 weeks thereafter, The patient underwent an UGI series, fiberoptic gastroscope and abdominal ultrasonography and was found to have a gastric midbody stricture. A total gastreetomy and Roux-en- Y esophagojejunostomy was performed. We report this case with brief review of the literature.
