Primary angiosarcomas of the breast are rare malignancy that account for fewer than 0.04% of all malignant breast tumors. The prognosis is poor. Surgery is the first line of treatment for angiosarcoma. Adjuvant chemotherapy and radiotherapy have been tried, but their efficacy remains controversial. Here we present the case of a 47-year-old woman with a palpable left breast mass that was diagnosed as a primary angiosarcoma. The patient underwent modified radical mastectomy with adjuvant chemotherapy and radiotherapy. Postoperatively, eighteen months later, the angiosarcoma recurred. The patient returned complaining of dyspnea and hemoptysis and was found to have a large pleural effusion. She developed a gradual onset of thrombocytopenia that persisted despite platelet transfusions. Finally, the patient died of respiratory failure secondary to pulmonary hemorrhage.

Methyl bromide is presently used as a fumigant for insects in soil, grains or fruit in storage or transport. It is a neurotoxic agent and has been responsible a number of deaths or acute poisonings among occupationally exposed persons. We report 2 patients, who had worked fumigation warehouse, presented with seizures and altered mental state. The serum concentrations of bromide were elevated 32.9 and 42.5 mg/l, respectively. Brain MRI showed bilateral symmetric high signal intensities in the splenium of corpus callosum, the globus pallidus, the quadrigeminal plate, the periaqueductal gray matter, the red nucleus, the substantia nigra, the medial lemniscus, the pontine tegmentum, the dentate nucleus, and the medulla. There was no brain lesion in the other patient. Appropriate and supervised handling of the chemical and regular education to workers are important to avoid the risk of methyl bromide poisoning.

OBJECTIVE: To determine the diagnostic performance of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and DCE ultrasound (DCE-US) for predicting response to neoadjuvant chemotherapy (NAC) in breast cancer patients. MATERIALS AND METHODS: This Institutional Review Board-approved prospective study was performed between 2014 and 2016. Thirty-nine women with breast cancer underwent DCE-US and DCE-MRI before the NAC, follow-up DCE-US after the first cycle of NAC, and follow-up DCE-MRI after the second cycle of NAC. DCE-MRI parameters (transfer constant [Ktrans], reverse constant [kep], and leakage space [Ve]) were assessed with histograms. From DCE-US, peak-enhancement, the area under the curve, wash-in rate, wash-out rate, time to peak, and rise time (RT) were obtained. After surgery, all the imaging parameters and their changes were compared with histopathologic response using the Miller-Payne Grading (MPG) system. Data from minor and good responders were compared using Wilcoxon rank sum test, chi-square test, or Fisher's exact test. Receiver operating characteristic curve analysis was used for assessing diagnostic performance to predict good response. RESULTS: Twelve patients (30.8%) showed a good response (MPG 4 or 5) and 27 (69.2%) showed a minor response (MPG 1–3). The mean, 25th, 50th, and 75th percentiles of Ktrans and Kep of post-NAC DCE-MRI differed between the two groups. These parameters showed fair to good diagnostic performance for the prediction of response to NAC (AUC 0.76–0.81, p ≤ 0.007). Among DCE-US parameters, the percentage change in RT showed fair prediction (AUC 0.71, p = 0.023). CONCLUSION: Quantitative analysis of DCE-MRI and DCE-US was helpful for early prediction of response to NAC.

Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal solid tumor commonly documented in children and young adults. Here, we report a case of IMT in colon confirmed pathologically after laparoscopic anterior resection. A 35-year-old man presented with anal bleeding after defecation for 2 weeks. Colonoscopy demonstrated a mass with shallow ulceration in the central area and irregular margin accompanied by intact mucosa in the descending colon. Computer tomography showed a well-demarcated and homogenous solitary mass in the descending colon. We performed laparoscopic anterior resection. This case was diagnosed as IMT after microscopic examination. The tumor was composed of a proliferation of spindle-shaped cells arranged in the hyaline material with chronic inflammatory cells, composed mainly of plasma cells and lymphocytes. Immunohistochemically, tumor cells were positive for smooth muscle actin, and vimentin, and negative for desmin, CD117 (c-kit), anaplastic lymphoma kinase-1.

PURPOSE: The purpose of this study was to evaluate the B-mode sonographic and sonoelastographic features of high risk lesions of the breast. MATERIALS AND METHODS: From April 2009 to February 2010, 1390 patients with breast lesions underwent US-guided core-biopsy. Among them, 13 lesions were confirmed to be pure sclerosing adenosis by subsequent surgical excision or on imaging follow-up of more than 1 year. Two radiologists retrospectively analyzed the B-mode sonography according to the Breast Imaging Reporting and Data System classification. The sonoelastographic images were classified into 5 elasticity scores according to the Itoh classification and the strain ratio between the mass and the surrounding fat tissue was reviewed. We considered the sonoelastographic patterns to be suspicious for the case with a score of 4 and 5 and a strain ratio of more than a 2.24. RESULTS: The common B-mode sonographic features of sclerosing adenosis were an irregular shape (69.2%, 9 of 13), an indistinct margin (92.3%, 12 of 13), hypoechogenicity (76.9%, 10 of 13) and category 4A, a low suspicion of malignancy (61.5%, 8 of 13). The common sonoelastographic features were a score of 2 (42%, 6 of 13) and a strain ratio < 2.24 (69.2%, 9 of 13). CONCLUSION: Sclerosing adenosis showed suspicious B-mode sonographic findings, but it had benign sonolastographic features.

OBJECTIVE: We were trying to identify the expression of Wnt 1 and beta-catenin in normal ovarian epithelium and epithelial ovarian tumor. METHODS: We used archival formalin-fixed and paraffin-embedded tissues from Comprehensive Gynecologic Cancer Center and the Department of Pathology at Bundang CHA Hospital from 2000 to 2005. Immunohistochemical staining for Wnt 1 and beta-catenin was performed on the ovarian epithelial tissues. Statistical analyses were performed with SPSS 10.1 for Windows and significance was defined as P<0.05. RESULTS: Of 114 cases, the cases were composed of 54 carcinomas, 40 borderline tumors, 12 benign tumors and 8 normal control ovarian tissues. Abnormal nucleocytoplasmic expression of beta-catenin was found in 4 endometrioid carcinomas. The nuclear expression of beta-catenin was found especially in the components of the endometrioid carcinoma (28.6%, P<0.05). Wnt 1 was overexpressed in all 9 clear cell carcinomas, but not frequent in the other types of malignant tumors (P<0.05). We found a statistically significant correlation between beta-catenin nuclear localization and endometrioid carcinomas. And we found a significant correlation between Wnt 1 expression and clear cell carcinomas. CONCLUSION: It does not seem that Wnt 1 over expression directly provoke the nuclear localization of beta-catenin. But, deregulation of beta-catenin and Wnt 1 may play a role in the pathogenesis of ovarian epithelial carcinogenesis of endometriod carcinoma and clear cell carcinoma. Evaluating this avenue of regulation of beta-catenin and Wnt protein in ovarian epithelial carcinoma may provide a new direction for early diagnosis and treatment in ovarian epithelial carcinoma and provide opportunities for making a certain biomarkers.

Fetal bilateral renal agenesis is a lethal congenital anomaly characterized by bilateral pulmonary hypoplasia, deformities and death due to severe oligohydramnios. This syndrome is associated with malformations of genitourinary tract, cardiovascular system, vertebral bodies or imperforated anus in more than half of the affected individuals. An early and reliable prenatal diagnosis is extremely important because it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, empty renal fossae. But poor sonographic resolution of severe oligohydramnios makes it difficult to diagnose the disease. We present a case of bilateral renal agenesis diagnosed at the 18th weeks gestation by using Transvaginal Ultrasonography and Color Doppler.

BACKGROUND: The grey zone of cervical cytology, and in particular atypical squamous cells, cannot exclude HSIL (ASC-H) causes diagnostic difficulties and increases medical expenses. We analyzed p16INK4a expression in ASC-H liquid-based cytology specimens (LBCS) to develop more effective methods for the management of ASC-H patients. METHODS: We carried out p16INK4a immunostaining with 57 LBCS of ASC-H diagnostic categories, all of which were histologically cofirmed and 43 cases of which were compared with the results of a human papillomavirus (HPV) chip test. RESULTS: p16INK4a immunostaining with ASC-H LBCS was positive in 20% (3/15) of cervicitis, 25.0% (3/12) of tissue-low-grade squamous intraepithelial lesion, 75.0% (18/24) of tissue-high grade squamous intraepithelial lesion (HSIL), and 100% (6/6) of invasive cancer cases. The positivity of p16INK4a in LBCS was correlated with higher grade of histologic diagnosis (r=0.578, p=0.000). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of p16INK4a immunostaining for the prediction of tissue-HSIL+ were 80.0%, 77.8%, 80.0%, and 77.8%, respectively. The sensitivity, specificity, PPV, and NPV of p16INK4a immunostaining plus HPV chip test for predicting tissue-HSIL+ were 71.2%, 86.4%, 84.2%, and 79.2%. CONCLUSIONS: p16INK4a immunostaining as well as HPV chip testing with remaining LBCS with ASC-H are useful objective markers for the prediction of tissue-HSIL+.

BACKGROUND/AIMS: The aims of this study were to determine subgoups of functional dyspesia and to evaluate the short-term effect of cisapride in patients with functional dyspepsia in Korea. METHODS: 1025 patients, with a mean age of 42.6 years, with symptoms of functional dyspepsia, were recruited consecutively and upper gastrointestinal symptoms were investigated by interview in 41 hospitals in Korea. In an open, multicenter trial, 1025 patients received Smg of cisapride three times a day (TID) for at least .2 weeks for the treatment of symptoms of functional dyspepsia. When necessary, the dose of cisapride was increased to 10mg TID and the duration of therapy was extended to 4 weeks. RESULTS: The most frequently reported symptoms of functional dyspepsia were epigastric discomfort or fullness (85%), bloating (70%), belching (53%), early satiety (52%) and epigastric pain (46%) retrospectively. Subgroups of functional dyspepsia were as follows; dysmotility-like 73.5%, ulcer-like 39.7%, reflux-like 13.0%, and unspecified dyspepsia 14.0%. However, 33.2% of subjects with functional dyspepsia could be classified into more than one subgroup. Upper gastrointestinal symptoms were decreased to average 50.3% (range; 42.2 to 59.2%) after 2 weeks of cisapride treatment and to 25% (19.2 to 29.9%) after 4 weeks. cisapride therapy resulted in good or excellent improvement in 59.0% of the patients after two weeks, in 75% of patients after 4 weeks. Adverse events were occurred in 52 patients (5.8% of all patients), most commonly, loose stools or diarrhea (3.5%), abdominal pain (1.1%), and dizziness (0.3%). The majority of adverse events was mild and transient in nature and led to premature discontinuation of treatment in 4 patients. CONCLUSIONS: Although the majorities of patients with functional dyspepsia have dysmotility like symptoms in Korea, there is such overlap among the dyspepsia subgroups. Most patients responded well to a short therapeutic trial with cisapride without significant side effects.
