Abstract PDF: A nodular density was detected on a chest radiograph taken from a 57-year-old Korean woman who was visiting a hospital for a routine check. Chest computed tomography revealed a 4.8 cm lobulated mass in the right lung and another focal nodular lesion in the left lung; biopsies of both lungs revealed adenocarcinoma. We conducted DNA sequencing and peptide nucleic acid clamping to investigate the potential double primary lung cancer. The results verified that the mass in the right lung had a mutation in the epidermal growth factor receptor, whereas the nodule in the left lung had a wild-type sequence, showing that these two were genetically different cancers from one another. Thus, we demonstrate that genetic testing is useful in determining double primary lung cancer, and we herein report on this case.

Simultaneous chylothorax and chylous ascites: Tae Soo Jang, In Beom Jeong, Do Yeun Cho, Sung Ju Kang, Oh Jung Kwon; Yeungnam Univ J Med. 2017;34(2):265-269. Published online December 31, 2017; DOI: https://doi.org/10.12701/yujm.2017.34.2.265

Abstract PDF: Chylothorax or chylous ascites are rare manifestations of liver cirrhosis. We report a rare case of simultaneous chylothorax and chylous ascites in a patient with hepatitis B virus-related liver cirrhosis. A 76-year-old woman was referred to our hospital with a pleural effusion on her right side. She had no history of recent medical procedures, trauma or tumor. There was no evidence of mass or thoracic duct obstruction in a computed tomography scan. Pleural fluid and ascites were confirmed as chylothorax and chylous ascites by chemistry analysis. Despite thorough conservative care, there was no improvement. Pleurodesis was planned, but hepatic encephalopathy developed suddenly and she did not recover.
