ABSTRACT
A choledochal cyst is relatively rare lesion in the biliary system, and a carcinoma arising from such a cyst is rarely reported. Until now, a case of a hepatocellular carcinoma combined with a choledochal cyst had not been reported. A 45-year-old woman was recently admitted due to abdominal pain. An abdominal computed tomography revealed a 5 cm-sized low attenuative mass involving the right anterior and left medial segment of the liver and gallbladder fossa. An endoscopic retrograde cholangiopancreatogram showed fusiform dilatation of the common bile duct, but anomalous union of pancreaticobiliary duct was not observed. Fine-needle aspiration of the liver was conducted and yielded a hepatocellular carcinoma. On celiac arteriography, a hypervascular hepatic mass was also found. Transarterial chemoembolization was performed. It is believed this may be the first case of a choledochal cyst combined with a hepatocellular carcinoma in the literature. Hence, this case is herein reported with a review of related literatures.

A 71-year-old man was admitted due to abdominal distension and periumbilical pain. He was diagnosed as having mucinous ductal ectasia (MDE) of the pancreas three months prior, but refused an operation. Three months later, an abdominal computed tomography revealed more dilated pancreatic duct, newly developed liver metastasis and ascites in comparison with previous findings. Fine-needle aspiration cytology of the cystic lesion in the pancreatic head was conducted and yielded adenocarcinoma. Also, an ascitic fluid cytology determined adenocarcinoma. This patient was diagnosed to be inoperable and received palliative chemotherapy and pain control. The patient expired 5 months after the initial diagnosis.

BACKGROUND: In patients with chronic obstructive pulmonary disease(COPD), it is well known that hypoxemia increases the frequency of VPB, which is associated with the poor prognosis such as sudden death. The aim of this study is to evaluate the effect of short and long-term low flow oxygen therapy on the development of VPBs in patients with COPD by correcting the hypoxemia. METHOD: In 19 patients with COPD, oxygen saturation and VPB are monitored by pulse oxymeter and 24-hour Holter EKG, with room air and the 1st and the 8th day during oxygen therapy by nasal prong (2L/min). RESULTS: The arterial oxygen saturation was significantly higher on the 1st day of oxygen therapy compared with breathing room air, and also higher on the 8th day of oxygen therapy than on the 1st day. We found that there was significant correlation between the minimal value of the arterial oxygen saturation and the mean value of the arterial oxygen saturation. The number of VPBs per hour was significantly higher on the 1st day of oxygen therapy compared with breathing room air, and also higher on the 8th day of oxygen therapy than on the 1st day. There was no significant correlation between the decrease of the frequency of VPBs and the increase of the minimal arterial oxygen saturation. But, because of the low p value as 0.056, The correlation is highly suggested. CONCLUSION: With oxygen therapy, the arterial oxygen saturation was increased and the number of VPBs was decreased, and with long-term oxygen therapy more than 7days, the number of VPBs was more decreased in patients with COPD.

Primary mediastinal nonseminomatous germ cell tumor associated with Klinefelter's syndrome is a rare disorder. We experienced a case of recurred primary mediastinal nonseminomatous germ cell tumor developed in a 24-year-old patient with Klinefelter's syndrome. The patient had been treated with surgery and combination chemotherapy under the diagnosis of primary mediastinal nonseminomatous germ cell tumor before. A round mass was found on the right lower lung field in the chest X-ray during follow up. The patient was diagnosed as recurred primary nonseminomatous germ cell tumor and Klinefelter's syndrome through tumor markers, peripheral blood karyotyping, and other tests including hormonal assay and was treated with combination chemotherapy and surgery again. When the patient is diagnosed as primary mediastinal nonseminomatous germ cell tumor, Klinefelter's syndrome and hematologic malignancies should be considered to be associated diseases and vice versa.
