Because most of the benign skin appendage tumors arise from pluripotential cells that form during adult life and possess the potentiality of differentiating in more than one direction, combinations of several tumor types can occur. We report a case of combined with eccrine poroma, clear cell hidradenoma, and syringocystadenoma papilliferum as a single tumor in a 41-year-old male who had suffered from a tumor on posterior neck for 5 years. The tumor was a relatively oval shaped pedunculated, and rubbery hard mass, measuring 3.5*3.0* 1.3cm in size. The outer surface was variegated and covered with hair. The diagnosis was confirmed by histopathological findings and surgical excision was done.

Recently, facial traumas are increasing due to expansion of motor vehicles and complexity of social life pattern. The zygoma bone is a prominent part of the midface and prone to be traumatized. Numerous approaches for reduction and fixation of zygomatic fractures have been described. Each reduction method has its advantages and disadvantages. The authors employed the external wire traction with fluoroscopy in cases of non-comminuted zygomatic arch fracture. The advantages of this method are a more accurate reduction under direct vision and takes a very short time. This procedure also can reduce the pain and edema after postoperation and possible under local anesthesia. With such method, we obtained satisfactory results cosmetically and functionally.

PURPOSE: Laparoscopic cholecystectomy (LC) is the standard management for acute cholecystitis. Percutaneous transhepatic gallbladder drainage (PTGBD) may be an alternative interim strategy before surgery in elderly patients with comorbidities. This study was designed to evaluate the safety and efficacy of PTGBD for elderly patients (>60 years) with acute cholecystitis. METHODS: We reviewed consecutive patients diagnosed with acute cholecystitis between January 2009 and December 2013. Group I included patients who underwent PTGBD, and patients of group II did not undergo PTGBD before LC. RESULTS: All 116 patients (72.7 +/- 7.1 years) were analyzed. The preoperative details of group I (n = 39) and group II (n = 77) were not significantly different. There was no significant difference in operative time (P = 0.057) and intraoperative estimated blood loss (P = 0.291). The rate of conversion to open operation of group I was significantly lower than that of group II (12.8% vs. 32.5%, P < 0.050). No significant difference of postoperative morbidity was found between the two groups (25.6% vs. 26.0%, P = 0.969). In addition, perioperative mortality was not significantly different. Preoperative hospital stay of group I was significantly longer than that of group II (10.3 +/- 5.7 days vs. 4.4 +/- 2.8 days, P < 0.050). However, two groups were not significantly different in total hospital stay (16.3 +/- 9.0 days vs. 13.4 +/- 6.5 days, P = 0.074). CONCLUSION: PTGBD is a proper preoperative management before LC for elderly patients with acute cholecystitis.

Brain meningioma, the most common benign brain tumor, has been reported to account for 13-26% of all intracranial tumors, with a crude incidence rate of 2.3 per 100,000 persons for all types of meningiomas. The prevalence of neuropsychiatric lupus erythematosus is 15-91% and its clinical manifestations are diverse: from mild cognitive dysfunction to serious neurological or psychiatric symptoms. Here, we report the first Korean patient with brain meningioma and systemic lupus erythematosus who had undergone surgical tumor resection.

We report a case of a 25-year old man with chronic kidney disease with secondary hyperparathyroidism who had persistent elevation of serum parathyroid hormone level after the immediate total parathyroidectomy and autotransplantation. To localize supernumerary (ectopic) parathyroid gland, we checked Tc-99m MIBI scintigraphy, MDCT and PET-CT. Contrast-enhanced MDCT showed a small strong enhancing lesion over left bracheocephalic vein, and PET-CT showed multiple brown tumors. We removed the supernumerary parathyroid gland and got a rapid drop of parathyroid hormone level.

PURPOSE: We previously reported that forkhead transcription factors of the O class 1 (FOXO1) expression in gastric cancer (GC) was associated with angiogenesis-related molecules. However, there is little experimental evidence for the direct role of FOXO1 in GC. In the present study, we investigated the effect of FOXO1 on the tumorigenesis and angiogenesis in GC and its relationship with SIRT1. MATERIALS AND METHODS: Stable GC cell lines (SNU-638 and SNU-601) infected with a lentivirus containing FOXO1 shRNA were established for animal studies as well as cell culture experiments. We used xenograft tumors in nude mice to evaluate the effect of FOXO1 silencing on tumor growth and angiogenesis. In addition, we examined the association between FOXO1 and SIRT1 by immunohistochemical tissue array analysis of 471 human GC specimens and Western blot analysis of xenografted tumor tissues. RESULTS: In cell culture, FOXO1 silencing enhanced hypoxia inducible factor-1alpha (HIF-1alpha) expression and GC cell growth under hypoxic conditions, but not under normoxic conditions. The xenograft study showed that FOXO1 downregulation enhanced tumor growth, microvessel areas, HIF-1alpha activation and vascular endothelial growth factor (VEGF) expression. In addition, inactivated FOXO1 expression was associated with SIRT1 expression in human GC tissues and xenograft tumor tissues. CONCLUSION: Our results indicate that FOXO1 inhibits GC growth and angiogenesis under hypoxic conditions via inactivation of the HIF-1alpha-VEGF pathway, possibly in association with SIRT1. Thus, development of treatment modalities aiming at this pathway might be useful for treating GC.

PURPOSE: Extremely elderly patients who present with complicated gallstone disease are less likely to undergo definitive treatment. The use of laparoscopic cholecystectomy (LC) in older patients is complicated by comorbid conditions that are concomitant with advanced age and may increase postoperative complications and the frequency of conversion to open surgery. We aimed to evaluate the results of LC in patients (older than 80 years). METHODS: We retrospectively analyzed 302 patients who underwent LC for acute cholecystitis between January 2011 and December 2013. Total patients were divided into three groups: group 1 patients were younger than 65 years, group 2 patients were between 65 and 79 years, and group 3 patients were older than 80 years. Patient characteristics were compared between the different groups. RESULTS: The conversion rate was significantly higher in group 3 compared to that in the other groups. Hematoma in gallbladder fossa and intraoperative bleeding were higher in group 3, the difference was not significant. Wound infection was not different between the three groups. Operating time and postoperative hospital stay were significantly higher in group 3 compared to those in the other groups. There was no reported bile leakage and operative mortality. Preoperative percutaneous transhepatic gallbladder drainage and endoscopic retrograde cholangiopancreatography were performed more frequently in group 3 than in the other groups. CONCLUSION: LC is safe and feasible. It should be the gold-standard approach for extremely elderly patients with acute cholecystitis.
