A wide range of denomination has been used for inflammatory myofibroblastic tumor (IMT). IMT is not entirely homogeneous, even though it shows some overlapping histologic features such as haphazard proliferation of spindle cell and polymorphic chronic inflammatory cell infiltraion. The spindle cell is considered to be of myofibroblastic origin but follicular dendritic cell origin was reported recently. IMT is known as nonneoplastic, aberrant inflammatory response. However, IMT could show local invasion, recurrence, vascular invasion, and malignant transformation, and clonal characteristics and aneuploidy of IMT support the hypothesis that IMT may be a neoplastic process. In order to define the nature of spindle cell of IMT, immunohistochemical stains for smooth muscle actin (SMA), vimentin (VMT), lysozyme, S-100 protein, cytokeratin, CD21 were done. Additional immunohistochemical stains for MIB-1 for proliferating activity and LMP (latent membrane protein) for Epstein-Barr virus (EBV) were done. IMTs were composed of each 2 cases from lung, liver and lymph node and one case from common bile duct, maxillary sinus, bladder and thigh, and were histologically subclassified according to Coffin et al. Nine cases (90%) were positive for SMA and VMT, but no correlation between SMA and VMT immunoreactivity and histologic types was identified. Five cases (50%) were positive for lysozyme and S-100 protein, and histologic type III was negative for lysozyme and S-100 protein, and immunoreactivity for S-100 protein was different according to the histologic subtypes. All 11 cases were negative for CD21 and EBV LMP. MIB-1 labelling index was less than 1% in all cases. In summary, the spindle cell is regarded as myofibroblastic origin rather than follicular dendritic cell origin. Relationship with EBV is not clear, and negligible MIB-1 reaction suggests that IMT might have a good prognosis.

We observed a case of sebaceous epithelioma associated with a nevus sebaceus in a 25-year-old male. The tumor was bean-sized, dome-shaped nodule on the slightly yellowish plaque of nevus sebaceus. Histopathological finding shows undifferentiated cells which are arranged in a palisade fashion at the periphery of a cell mass and a fairly large number of transitional cells and groups of mature sebaeeous cells.

Purpose:
Proper use of antibiotics during emergency abdominal surgery is essential in reducing the incidence of surgical site infection. However, no studies have investigated the type of antibiotics and duration of therapy in individuals with abdominal trauma in Korea. We aimed to investigate the status of initial antibiotic therapy in patients with solitary abdominal trauma.
Methods:
From January 2015 to December 2015, we retrospectively analyzed the medical records of patients with solitary abdominal trauma from 17 institutions including regional trauma centers in South Korea. Both blunt and penetrating abdominal injuries were included. Time from arrival to initial antibiotic therapy, rate of antibiotic use upon injury mechanism, injured organ, type, and duration of antibiotic use, and postoperative infection were investigated.
Results:
Data of the 311 patients were collected. The use of antibiotic was initiated in 96.4% of patients with penetrating injury and 79.7% with blunt injury. Initial antibiotics therapy was provided to 78.2% of patients with solid organ injury and 97.5% with hollow viscus injury. The mean day of using antibiotics was 6 days in solid organ injuries, 6.2 days in hollow viscus. Infection within 2 weeks of admission occurred in 36 cases. Infection was related to injury severity (Abbreviated Injury Scale of >3), hollow viscus injury, operation, open abdomen, colon perforation, and RBC transfusion. There was no infection in cases with laparoscopic operation. Duration of antibiotics did not affect the infection rate.
Conclusion
Antibiotics are used extensively (84.2%) and for long duration (6.2 days) in patients with abdominal injury in Korea.

"Tumor-to-tumor" metastasis is a rare event; meningioma has been reported as the most common primary intracranial tumor to harbor cancer metastases. Several hypotheses have been previously proposed to explain this occurrence, but the exact mechanism by which these metastases develop into meningiomas is not yet understood. Magnetic resonance imaging and spectroscopy have been valuable diagnostic tools, but preoperative diagnosis of metastasis to meningioma remains highly difficult. We present a case report of a metastasis of non-small cell lung cancer into an intracranial meningioma.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

OBJECTIVE: The aim of study was to evaluate the efficacy of medical and/or laparoscopic surgical treatment for improvement of reproductive outcome of in vitro fertilization and embryo transfer (IVF-ET) in the patients with endometriosis. METHODS: 296 IVF-ET cycles except 18 cycles of cancelled embryo-transfer (unfertilization; 16 cycles, high risk of ovarian hyperstimulation syndrome; 2 cycles) in 191 infertile women with endometriosis from January 1, 1995 to December 31, 1998 were included in this study. All women's ages were < or = 35 and the factor for infetility was endometriosis only and day 3 follicle stumulating hormone (FSH) level of all the cycles was < or = 10 mIU/ml in this study. All the baseline study about infertility was done before initiating treatment of infertility. The stage of endometriosis was recorded during diagnostic laparoscopy by WHO critera. Medical treatment (GnRH agonist or danazole) or laparoscopic surgery was done independently or combinedly by the physician's decision according to the disease entity and symptoms. Short or long protocols were used for controlled ovarian hyperstimulation and 3 day embryos were transferred (maximally 4 embryos) by standard procedures in our institute. We classified the cases as 4 groups : group 1 (without pre-treatment, 80 cycles), goup 2 (laparoscopic surgery only, 37 cycles), group 3 (medication only, 140 cycles), group IV (combined pre-treatment, 39 cycles). RESULTS: The mean age (years old, mean +/- SEM) was 31.5 +/- 0.3 (group 1), 31.6 +/- 0.5 (group 2), 31.5 +/- 0.2 (group 3), 31.7 +/- 0.4 (group 4) respectively. The duration of infertility (months) was 57.7 +/- 3.3, 64.5 +/- 4.8, 59.1 +/- 1.9, 52.0 +/- 3.7 respectively among groups. The viable pregnancy rate (over 28 gestational weeks, VPR) was 12.5 % (10/80) in goup 1, 13.5 % (5/37) in goup 2, 14.3 % (20/140) in group 3, 30.8 % (12/39) in group 4 and there was statistically significant difference between group 1 and group 4 (P=0.03, Chi square test). The total used gonadotropins (ampules) for controlled ovarian hyperstimulation were 28.2 +/- 0.6.

PURPOSE: To report the ophthalmic manifestations of neurofibromatosis in Korea. METHODS: Ophthalmologic examinations were performed from November 2001 to January 2008 for 153 consecutive patients who were diagnosed with neurofibromatosis according to the diagnostic criteria for neurofibromatosis. A retrospective analysis was performed according to the medical records of these 153 patients. RESULTS: Seventy seven out of the 153 patients were men, 76 were women and the mean age was 20.44 +/- 14.34 years old. One hundred twelve were neurofibromatosis type 1 and six were neurofibromatosis type 2. Remained thirty five were segmental neurofibromatosis type 1. Ophthalmic manifestations of the neurofibromatosis type 1 were Lisch nodule (52.68%), high myopia (14.29%), plexiform neurofibroma in the orbit (4.46%), cafe au lait spots (4.46%) and optic glioma (3.58%). In the neurofibromatosis type 2, epiretinal membrane (33.33%) showed highest incidence and posterior subcapsular opacity (16.67%), Lisch nodule (16.67%), optic disc edema (16.67%), and optic nerve glioma (16.67%) were also noted. Lisch nodule (25.71%) was the most common ophthalmic finding in segmental neurofibromatosis type 1. CONCLUSIONS: Lisch nodule, which was the most common manifestation of the neurofibromatosis type 1, was less manifested in our cases compared to the previous reports of western countries. In the neurofibromatosis type 2, epiretinal membrane and posterior subcapsular cataract showed higher incidence than those of other types of neurofibromatosis.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. Frequent sites of extrahepatic metastasis are the lung, adrenal gland, bone, etc. But, cutaneous metastasis from HCC is rare event. Several cases of subcutaneous seeding after percutaneous transhepatic biopsy or aspiration of liver were reported, however, most of these cases had solitary nodular lesion which was located at the biopsy site. We experienced a case of multiple cutaneous metastasis on whole body from HCC which was not related to percutaneous transhepatic biopsy of liver in a 34-ear-ld male patient. Thus, we report a case of multiple cutaneous metastasis from HCC with brief review of related literature.

PURPOSE: The purpose of this study was to evaluate the diagnostic accuracy of Tc-99m labeled antigranulocyte antibody immunoscintigrapy in the diagnosis of osteomyelitis and compare with the results of triphasic bone scan. MATERIALS AND METHODS: The study population was 39 patients (22 male, 17 female) who had uncertain diagnoses of osteomyelitis. Fifteen patients had history of orthopedic surgery, and 5 had previous fracture. One milligram of monoclonal antibody against NCA-95 was labeled with 370 MBq of Tc-99m, injected intravenously, and 4 hour images were obtained. Triphasic bone scan images were obtained in 30 p;tients. The final diagnosis was confirmed by bacteriologic culture, biopsy or long term clinical follow up. RESULTS: Twenty one patients were confirmed to have osteomyelitis (1 acute, 20 chronic). Eighteen patients were without osteomyelitis. Antigranulocyte antibody immunoscintigraphy had a sensitivity of 71% (15/21), and a specificity of 89% (16/18), while the sensitivity and specificity of triphasic bone scan was 93% (13/14) and 38% (6/16), respectively. Antigranulocyte antibody scan showed higher specificity of 100% (11/11) in comparison with 33% (3/9) of triphasic bone scan in patients with history of orthopedic surgery or fracture. CONCLUSION: Antigranulocyte antibody immunoscintigraphy is more specific than that of triphasic bone scan and may be helpful in patients with history of surgery or fracture. However, sensitivity is lower than triphasic bone scan in the detection of chronic osteomyelitis.
