Primary liver tumors are uncommon in childhood, with a relative frequency of 3 % of all childhood tumors. Seventy-three cases of pediatric primary liver tumors operated on at single institution between 1986 and 2002 were reviewed. Malignant tumors included 37 cases of hepatoblastoma, 11 hepatocellular carcinomas, 6 undifferentiated (embryonal) sarcomas, and 1 mixed germ-cell tumor. Benign tumors constitute only 24.6 % of liver tumors, including 7 hemangioendotheliomas, 5 mesenchymal hamartomas, 3 congenital cysts, and one each with focal nodular hyperplasia and hemangioma. The common presenting clinical features were abdominal mass or abdominal distension. Anatomical hepatic resections were carried out in 38 cases, and nonanatomical resections in 34 cases. One patient died of a direct result of hepatic resection (1.4 %). The complication rate was 16.4 %.

A 61-year-old male who complained of right upper quadrant pain was referred to the authors for evaluation after his computed tomography suggested biliary adenocarcinoma. The lesion consisted of multiple cysts with papillary mass and peri-ampullay mass. The patient underwent an operation due to a clinical suspicion of biliary cystadenocarcinoma, but the pathology confirmed biliary papillomatosis (BP) after diagnosing intrahepatic papillary neoplasm with high-grade dysplasia and invasive adenocarcinoma with papillary neoplasm from the distal common bile duct to the duodenum. BP is a disease characterized by multiple papillary masses. Its cause has yet to be discovered. It commonly manifests as bile duct dilation but rarely as a ductal cystic change. Under computed tomography or magnetic resonance imaging, both the BP and the cystic neoplasm can show bile duct dilation and a papillary mass, which makes their differential diagnosis difficult. A confirmative diagnosis can be made through a pathologic examination. BP is classified as a benign disease that can become malignant and may recur, though rarely. Its treatment of choice is surgical resection. Laser ablation or photodynamic therapy can be used for unresectable lesions. In the case featured in this paper, biliary papillomatosis was difficult to differentiate from cystic adenocarcinoma due to diffusely scattered multiple large cystic lesions in the liver, and it was histologically confirmed to have become malignant with cystic duct dilation after the operation. This case is reported herein with a literature review.

췌장암은 예후가 매우 불량한 암으로 수술적 절제술을 시행하여도 대부분의 경우 재발을 한다고 알려져 있다. 재발을 하는 경우 대개 항암화학요법을 시행하게 되나, 그 반응 또한 좋지 않은 것으로 알려져 있다. 간에 국소적으로 재발을 했을 경우 종양절제술을 시행하는 것에 대해서는 몇몇 보고가 있는 정도이며, 생존율을 향상시킬 수 있는지에 대해서는 연구가 거의 없는 상태이다. 본 증례는 유문보존 췌십이지장 절제술 시행 후 간에 국소적으로 재발한 췌장암에 대하여 gemcitabine 및 capecitabine과 oxaliplatin 병합 항암화학요법을 시행하였으나 크기가 증가하였고, 이에 종양절제술을 시행하였으며, 이후 장기생존을 보였던 경우로 매우 드문 증례를 경험하였기에 보고하는 바이다.

Although significant advances in the treatment of intrahepatic lesions, it is reported that the prognosis for patients with hepatocellular carcinoma (HCC) who have extrahepatic metastasis remains poor. We report a patient with lung, liver, brain, bone and subcutaneous metastasis from HCC who has survived more than 7 years maintaining relatively good performance status as a result of repeated therapies. A 55-year-old male patient with HCC underwent right lobectomy of the liver and cholecystectomy in September 2006. He received wedge resection for lung metastasis twice (July 2009, January 2011) and Gamma Knife stereotactic radiosurgery for brain metastasis (April 2011). Over the last 3 years, he has developed metastasis in subcutaneous tissues, muscle, and bone with pain. He has undergone 7 courses of radiotherapies for subcutaneous tissues, muscle, and bone metastasis and been prescribed sorafenib and he is still capable of all self-care.

A primary metastatic malignant plasma cell tumor was presented in a 7-year-old, female, mixed breed dog. The dog was admitted to Veterinary Teaching Hospital at College of Veterinary Medicine, Seoul National University after suffering from depression, anorexia, and dyspnea. The dog was euthanized due to poor prognosis. At necropsy, numerous, firm and tan round nodules, 1 to 2 cm in diameter were noted in the ribs. The nodules formed chain or were occasionally coalescing, causing osteolysis of the ribs. A large amount of clear fluid was present in the thoracic cavity. The spleen and liver were markedly enlarged and congested. Histologically, the nodular masses were diagnosed as plasma cell tumor which was believed to be originated from the rib. Evidence of metastasis was observed in the spleen, liver, and kidney.

This study aims to report a case of rectosigmoid neuroendocrine tumor patient with liver metastasis whose outstanding carcinoid symptom was mucosal diarrhea for more than 10 times a day. Three different herbal decoctions were administered orally for the treatment of diarrhea which was among carcinoid symptoms from diffuse metastatic liver lesion. The herbal decoctions given were modified Lijung-tang, modified Sambaek-tang and modified Jeokseokjiuyeoryang-tang. The administration period was 5, 14 and 9 days respectively. Frequency of patient's mucosal diarrhea had increased consistently during hospitalization. It had almost doubled compared to pre-hospitalization up to 27 times/24 hrs. But during the period of modified Sambaek-tang administration, frequency of diarrhea was maintained between 9 to 15 times/24hrs. There was no difference of liver tumors between Nov 16th 2013 and Dec 9th 2013 in computed tomography images. Three conventional established herbal prescriptions administered in this case didn't show any favorable effect on improving mucosal diarrhea induced by carcinoid symptoms of a rectosigmoid neuroendocrine tumor with liver metastasis. Even if modified Sambaek-tang showed partial effect on frequency of diarrhea, we concluded that it was not sufficient to be a therapeutic method of the diarrhea as carcinoid symptom. Furthermore, it is necessary to conduct additional studies about the diarrhea of neuroendocrine tumor with liver metastasis.

Objective: To compare the performance of the deep learning-based lesion detection algorithm (DLLD) in detecting liver metastasis with that of radiologists. Materials and Methods: This clinical retrospective study used 4386-slice computed tomography (CT) images and labels from a training cohort (502 patients with colorectal cancer [CRC] from November 2005 to December 2010) to train the DLLD for detecting liver metastasis, and used CT images of a validation cohort (40 patients with 99 liver metastatic lesions and 45 patients without liver metastasis from January 2011 to December 2011) for comparing the performance of the DLLD with that of readers (three abdominal radiologists and three radiology residents). For per-lesion binary classification, the sensitivity and false positives per patient were measured. Results: A total of 85 patients with CRC were included in the validation cohort. In the comparison based on per-lesion binary classification, the sensitivity of DLLD (81.82%, [81/99]) was comparable to that of abdominal radiologists (80.81%, p = 0.80) and radiology residents (79.46%, p = 0.57). However, the false positives per patient with DLLD (1.330) was higher than that of abdominal radiologists (0.357, p < 0.001) and radiology residents (0.667, p < 0.001). Conclusion: DLLD showed a sensitivity comparable to that of radiologists when detecting liver metastasis in patients initially diagnosed with CRC. However, the false positives of DLLD were higher than those of radiologists. Therefore, DLLD could serve as an assistant tool for detecting liver metastasis instead of a standalone diagnostic tool.

간에 생기는 단발성 괴사성 결절은 매우 드문 양성 질환으로 대개 아무 증상 없이 우연히 발견되고, 간에서 생길 수 있는 여러 가지 단발성 병변과의 감별을 필요로 하며, 특히 악성 종양의 병기 결정에 있어서 간내 전이암과 구별하는 것은 매우 중요하다고 알려져 있다. 영상의학적으로 간의 단발성 괴사성 결절은 조영증강이 얼거나 미약한 주변부 조영증강을 보이는 경계가 좋은 간내 결절로 보고되고 있다. 하지만 단발성 괴사성 결절이 영상에서 과녁 모양으로 보이는 경우는 지금까지 보고된 바 없으며, 특히 고자장의 자기 공명 영상과 양성자 방출 단층 촬영 소견이 보고된 경우도 전무하다. 이에 저자들은 조기 위암 환자에서 과녁 모양으로 보여 전이암과 감별이 어려웠던 간내 단발성 결절을 경험하여 이의 다양한 영상 소견을 보고하고자 하며, 병리학적 소견과 이에 대한 문헌 고찰을 통해 원인을 알아 보고자 하였다.
