Granuloma faciale is a rare disease of unknown origin characterized by single or multiple cutaneous nodules usually occurring on the face. A narrow grenz zone of normal dermis is usually observed between the epidermis and the dense dermal polymorphous infiltrates. We report a case of granuloma faciale in a 40-year-old male patient with erythematous plaque on his nose. The skin biopsy specimen showed a dense dermal accumulation of inflammatory cells, including neutrophils, eosinophils, monocytes, and lymphocytes. The infiltrate was distributed diffusely throughout the involved dermis and it focally involved the thinned and flattened epidermis. There is deposition of fibrinoid material within and around the affected lood wessels. The lesion was treated with CO2 laser effectively.

It is known that neutropenia caused by combination pegylated interferon plus ribavirin therapy for hepatitis C virus (HCV) infection is well tolerated and carries a negligible risk of infection. Neutropenic enterocolitis is encountered most frequently in patients with hemato-oncologic diseases who are undergoing intensive chemotherapy. However, little information exists regarding this life-threatening event in the setting of HCV therapy. We present here an unusual case of fatal neutropenic enterocolitis in a cirrhotic patient receiving combination therapy for HCV infection. This is the first report of a death from neutropenic enterocolitis associated with treatment for chronic HCV infection. The present case suggests that caution should be exercised when continuing HCV therapy in neutropenic patients with advanced fibrosis, and the decision to maintain such therapy should be balanced against the potential for serious adverse events.

Although continuous low-dose (metronomic [MET]) therapy exerts anti-cancer efficacy in various cancer models, the effect of long-term MET therapy for hepatocellular carcinoma (HCC) remains unknown. This study assessed the long-term efficacy of MET on suppression of tumor growth and spontaneous metastasis in a rat model of HCC induced by administration of diethylnitrosamine for 16 wk. The rats were divided into 3 groups: MTD group received intraperitoneal (i.p.) injections of 40 mg/kg cyclophosphamide on days 1, 3, and 5 of a 21-day cycle; Control and MET groups received i.p. injections of saline and 20 mg/kg cyclophosphamide twice a week, respectively. Anti-tumor and anti-angiogenic effects and anti-metastatic mechanisms including matrix metalloproteinases (MMPs) and tissue inhibitors of MMPs (TIMPs) were evaluated. Twelve wk of MET therapy resulted in a significant reduction in intrahepatic tumors than control or MTD therapy. The MET group had fewer proliferating cell nuclear antigen-positive cells and decreased hypoxia-inducible factor-1alpha levels and microvessel density. Lung metastases were detected in 100%, 80%, and 42.9% in the control, MTD, and MET groups, respectively. MET therapy significantly decreased expression of TIMP-1, MMP-2 and -9. For mediators of pro-MMP-2 activation, MET therapy induced significant suppression in the TIMP-2 and MMP-14 level. The survival in the MET group was significantly prolonged compared to the control and MTD groups. Long-term MET scheduling suppresses tumor growth and metastasis via its potent anti-angiogenic properties and a decrease in MMPs and TIMPs activities. These results provide a rationale for long-term MET dosing in future clinical trials of HCC treatment.

Epithelioid hemangioendothelioma is a neoplasm of vascular origin with a low-to-intermediate malignant potential and is one of the rare sarcomas arising from the liver. Its etiology is unknown and its clinical outcome is unpredictable. There is no generally accepted therapeutic strategy because of its rarity and the variable natural course between hemangioma and angiosarcoma. We report a case of a 64-year old woman who underwent hepatic resection due to epithelioid hemangioendothelioma in the right lobe that progressed to extrahepatic metastases of the bone, pleura, and peritoneum 22 months later. However, after resection there was no primary hepatic recurrence.

Reactivation of hepatitis B virus (HBV) replication is a frequent phenomenon in patients receiving immunosuppressants or chemotherapy. It was recently reported that regional therapy, such as transarterial chemotherapy (TAC) or radiotherapy, can also induce HBV reactivation in patients with hepatocellular carcinoma (HCC), and this can be prevented by preemptive lamivudine treatment. We report an unusual case of fatal hepatitis caused by reactivation of the tyrosine-methionine-aspartate-aspartate (YMDD) lamivudine-resistant strain in a 51-year-old male patient with HCC who was receiving preemptive lamivudine therapy. This patient received combined helical tomotherapy and TAC for the treatment of HCC with pulmonary metastasis. HBV reactivation and hepatitis exacerbation occurred after 2 months of therapy, but preemptive antiviral therapy was continued. Laboratory tests showed that the serum HBV DNA level had increased by more than 10,000-fold and a severe elevation of the aminotransferase level to 1,060 U/L. Although adefovir was added to lamivudine immediately after detecting the YMDD mutants, the patient eventually died of hepatic failure. Our experience suggests that for preemptive therapy, the use of potent antiviral drugs with a low risk of drug resistance as well as close viral monitoring are important for chronic HBV carriers undergoing intensive anticancer therapy.

BACKGROUND/AIMS: We compared the recurrence of hepatocellular carcinoma (HCC) and the survival of patients who received radiofrequency ablation (RFA) after transarterial chemoembolization (TACE) with patients treated with TACE or RFA alone. METHODS: This study included 201 patients with HCC, who were consecutively enrolled at Seoul St. Mary's Hospital between December 2004 and February 2010. Inclusion criteria were a single HCC < or = 5.0 cm or up to three HCCs < or = 3.0 cm. We used a propensity score model to compare HCC patients (n = 87) who received RFA after TACE (TACE + RFA) with those who received TACE (n = 71) or RFA alone (n = 43). RESULTS: The median follow-up period was 33.3 months (range, 6.8 to 80.9). The TACE + RFA group showed significantly lower local recurrence than the RFA or TACE groups (hazard ratio [HR], 0.309; 95% confidence interval [CI], 0.130 to 0.736; p = 0.008; and HR, 0.352; 95% CI, 0.158 to 0.787; p = 0.011, respectively). The overall survival was significantly better in the TACE + RFA group compared to the RFA group (HR, 0.422; 95% CI, 0.185 to 0.964; p = 0.041). However, the survival benefit was not different between the TACE + RFA and TACE groups (p = 0.124). Subgroup analysis showed that among patients with a tumor size < 3 cm, the TACE + RFA group had significantly better long-term survival than those in the TACE or RFA groups (p = 0.017, p = 0.004, respectively). CONCLUSIONS: TACE + RFA combination treatment showed favorable local recurrence and better overall survival rates in early-stage HCC patients. Patients with tumors < 3 cm are likely to benefit more from TACE + RFA combination treatment. Additional studies are needed for the selection of suitable HCC patients for TACE + RFA treatment.

Epstein-Barr virus (EBV) infection varies in its clinical manifestations and severity. EBV can be a causative agent of hepatitis and may have a role in the pathogenesis of chronic autoimmune diseases including inflammatory bowel disease. A 24-year-old woman was admitted to our hospital, presenting with fever and elevated liver enzymes. She was diagnosed with acute hepatitis and EBV infection according to serologic tests and liver biopsy. Within two months, she was re-admitted to our hospital, presenting with hematochezia and lower abdominal pain. She was diagnosed with ulcerative colitis. In situ hybridization for EBV was positive in initial liver biopsy and colon biopsy. Here we report an unusual case of acute EBV hepatitis followed at a short interval by ulcerative colitis.

Most pancreatic pseudocysts are located in or around the pancreas, but they can be found in all the potential spaces around viscera in and outside of the abdominal cavity. The complications of pancreatic pseudocysts are infection, rupture, fistula, obstruction and hemorrhage. However, an upper gastrointestinal bleeding caused by pancreatic pseudocyst is rare. Pseudocysts with complication like hemorrhage require percutaneous, endoscopic or surgical treatment. We report a case of the pancreatic pseudocyst involving duodenal wall with upper gastrointestinal hemorrhage, which was improved by conservative treatment.

The role of radiotherapy in the treatment of hepatocellular carcinoma (HCC) has been limited to date, because the liver has a low tolerance to radiation. However, reconstructing tumors and surrounding organs via a three-dimensional conformal planning system can avoid excess radiotherapy exposure to the rest of the liver and adjacent organs. Recently, the concept of "adaptive radiotherapy," such as with helical tomotherapy, has been introduced for treating HCC. Helical tomotherapy obtains an image from the computed tomography component, which allows targeted regions to be visualized prior to, during, and immediately after each treatment and delivers intensity-modulated radiation therapy. We report two patients with advanced HCC who underwent tomotherapy treatment. One was a patient afflicted with advanced HCC and a portal vein tumor thrombus, which was treated with tomotherapy combined with transarterial chemolipiodolization. The other was a patient afflicted with multiple pulmonary metastases treated with tomotherapy followed by systemic chemotherapy.

BACKGROUND/AIMS: Obstructive sleep apnea is becoming more important in gastroesophageal reflux disease (GERD) patients. This study investigated the prevalence of high risk for obstructive sleep apnea in GERD patients in comparison with that in healthy controls using the Berlin Questionnaire. We also investigated the risk factors for obstructive sleep apnea in GERD patients. METHODS: We enrolled 1,007 subjects: 776 healthy controls, 115 individuals with erosive reflux disease, and 116 with non-erosive reflux disease. GERD was diagnosed and classified using endoscopy and a reflux questionnaire. The Berlin Questionnaire was used to evaluate obstructive sleep apnea. RESULTS: More patients in the GERD group (28.2%) had higher risk for obstructive sleep apnea than healthy controls (20.4%, P = 0.036). More patients with non-erosive disease (32.8%) had higher risk for obstructive sleep apnea (OSA) than patients with erosive disease (20.9%) and controls (20.4%, P = 0.010). On multivariate analysis, non-erosive disease was a high risk factor for obstructive sleep apnea (odds ratio [OR], 1.82; P = 0.011). Age > or = 55 years (OR, 1.83; P < 0.001) and a high body mass index (> or = 25 kg/m2) (OR, 2.76; P < 0.001) were also identified as risk factors. Nocturnal GERD was related to high risk for OSA in non-erosive disease patients (OR, 2.97; P = 0.019), but not in erosive disease patients. CONCLUSIONS: High risk for OSA is more prevalent in GERD patients than in controls. Non-erosive reflux disease, age > or = 55, and a high BMI are associated with high risk for OSA.
