Malignant mesothelioma of the tunica vaginalis is an externally rare tumor arising from the serosal surface of the pleural, pericardial, peritoneal cavities. The pathologic diagnosis was based upon the clinical, gross and microscopic findings and immunohistochemical studies. Appropriate treatment of malignant mesothelioma consists of inguinal orchiectomy with close follow up. Treatment of locally recurrent and distant metastasis have not been standardized. We report a case of metastatic malignant mesothelioma from the tunica vaginalis of the right spermatic cord with coincident finding of left renal cell carcinoma, that was metastasis to the abdominal wall, 17months after right radical orchiectomy and left radical nephrectomy.

PURPOSE: To analyze the enhancement patterns and morphology of peripheral cholangiocarcinomas (CCs), as seen on three-phase helical CT. MATERIALS AND METHODS: Three-phase helical CT scans of 25 cases of 24 patients with pathologically-proven CCs were retrospectively reviewed. After intravenous administration of contrast media, scans of the hepatic arterial phase (HAP) were obtained at 30 seconds, of the portal venous phase (PVP) at 70 seconds, and of the delayed phase (DP) at 3 minutes. RESULTS: Linear, dense, marginal enhancement was seen in 17 CCs (68%), mainly on HAP images (64%) while thick, band-like, peripheral enhancement was seen in 18 (72%), on either PVP (52%) or DP (44%). Internal enhancement was observed in 23 CCs (92%) on PVP (68%) and/or DP (88%), and 19 CCs (76%) among them showed incomplete enhancement of stippled and/or septated patterns. Most (76%) were seen throughout all three phases to be hypoattenuating, as compared to the surrounding parenchyma. On HAP, wedge-shaped parenchymal enhancement was demonstrated at the periphery of 19 CCs (76%) suggesting impaired portal flow. Associated morphologic findings were satellate nodules (n=15, 60%), lymphadenopathy (n=14, 56%), focal dilatation of intrahepatic ducts around the tumor (44%), umbilication of the liver surface (50%), and clonorchiasis (44%). CONCLUSION: On three-phase helical CT, peripheral cholangiocarcinoma showed linear marginal enhancement on HAP, thick peripheral enhancement on PVP and/or DP, stippled and septated enhancing foci on DP, and peritumoral wedge enhancement on HAP. Associcated findings such as satellite nodules, focal dilatation of the intrahepatic ducts, umbilication of the tumor, and clonorchiasis were helpful.

OBJECTIVE: This study was designed to examine the pharmaco-dynamic pattern of proteomic expression in cervical carcinoma cells (CaSki cell line; HPV-16 positive) after in vitro treatment by the etoposide. METHODS: We analyzed proteomic profiling in cervical carcinoma cells after etoposide treatment using two-dimensional gel electrophoresis (2-DE) with MALDI-TOF-MS used for protein identification. Then, we tested the several experimental methods for verification and functional identification, including MTT assay, PI staining, DNA fragmentation assay, FDA, FACS and Western blot analysis. RESULTS: Etoposide inhibited the CaSki cervical cancer cell growth in a dose-dependent manner and the optimal concentration of etoposide is 2micrometer(IC50) in the CaSki cervical cancer cells. The etoposide induced apoptosis, as determined by DNA fragmentation assay, FACS, and Western blot. The etoposide increased the protein expression of Fas (Apo-1/CD95), p53, pRb and caspase-3, but decreased the level of Bcl-2 and caspase-3 precursor and subsequently triggered the mitochondrial apoptotic pathway (release of cytochrome c and activation of caspase-9). To this end, we analyzed CaSki cancer cells using 2-DE. Eight proteins (XAP-5, HXC-36, serine/threonine protein phosphatase 2B catalytic subunit, G2/mitotic-specific cyclin B1, T-box transcription factor TBX20, diacylglycerol kinase, amiloride-sensitive amine oxidase, HEF-like protein, ras-related protein Rab-20) were down-regulated and nine proteins (RNA 3'-terminal phosphate cyclase-like protein, late endosomal/lysosomal Mp1 interacting protein, glia maturation factor, replication protein A 14 kDa subunit, mago sashi protein homolog, 14 kDa phosphohistidine phosphatase, protein C14 or f48, cyclin-dependent kinase 4 inhibitior A, retinoic acid-binding protein II) were up-regulated in etoposide-treated CaSki cells when compared with non-treated cells. CONCLUSION: Our results clearly indicate that etoposide induced cell death by apoptosis. These findings may provide insights into the mechanisms underlying the apparent anti-tumoral effects of etoposide.

A case of primary adenosquamous carcinoma of the liver is reported. A large cystic mass with irregular enhancing wall was seen in the left lobe of the liver; multiple hepatic cysts and metastatic nodules were scattered in both lobes. Sonoguided needle biopsy was performed and on histopathology, adenosquamous carcinoma was diagnosed. The radiologic and pathologic relationships of this unusual neoplasm are discussed.

Primary epiploic appendagitis of the colon is a rare cause of abdominal pain and is a self-limiting disease. Double contrast barium enema showed a smooth extrinsic compression located anterolateraly to the involved colon. Ultrasonography revealed a non-compressible echogenic ovoid mass attached to the colon wall. On abdominal CT, all lesions were seen as pedunculated ovel fatty masses with surrounding streaky densities connected to the serosal surface of the adjacent colon. Follow up CT performed 13-25(mean 18) days later showed that during this intrval, the volume of the mass and extent of surrounding infiltrations had decreased.

The circumsporozoite protein (CSP) of Plasmodium spp. is a diagnostic antigen and useful biomarker for monitoring short-term/seasonal changes to malaria transmission. Using P. vivax CSP antibody ELISA, epidemiological characteristics were analyzed in the residents of Ganghwa, Cheorwon, Paju, and Goseong from 2017 to 2018. In Ganghwa and Cheorwon, 1.6% and 1.2% of residents, respectively, were PvCSP-antibody-positive in 2018, which indicates a decrease of 0.4% in the positive rate compared to 2017. The annual parasite incidence (API) in Ganghwa and Cheorwon was 24.9 and 10.5 in 2017 and 20.3 and 10.7 in 2018, respectively. Although the changes were not significant, the API in Ganghwa decreased slightly by 4.5 in 2018 compared to the previous year. In Paju and Goseong, 3.9% and 2.0% of residents were positive for the PvCSP antibody. The API in Paju was 13.1 in 2017 and 16.0 in 2018, although no malaria patients were reported for the 2 years. Therefore, the results suggest that PvCSP is a useful antigen for confirming initial malaria infection. Additionally, considering that the antibody is relatively transient, it can be employed for sero-epidemiological studies to determine the extent of malaria transmission in the current year.

Recently, favorable outcomes have been reported after the endovascular treatment of either ruptured or unruptured paraclinoid aneurysms. The complications specifically related to the endovascular treatment of paraclinoid aneurysms have also been reported in other studies. Visual symptoms related to the mass effects associated with giant paraclinoid aneurysm normally improve after coil embolization. However, these symptoms have also been reported to be exacerbated in some cases. The authors here report an unusual case of progressive visual loss occurring after endovascular coiling treatment in a case of a large paraclinoid aneurysm.
