We report a patient with combined hepatocellular-cholangiocarcinoma confined in the common hepatic duct and scirrhous type of hepatocellular carcinoma in the caudate lobe of liver simultaneously. The patient was a 55-yearsold Korean man with hepatitis B virus (HBV) carrier who was referred from a local hospital due to detected liver mass on abdominal computed tomography (CT). He has presented jaundice and weight loss for the previous 3 weeks. Laboratory examination showed AST/ALT elevation and hyperbilirubinemia. HBsAg was positive. The tumor marker study showed elevated AFP and DCP, not CEA and CA 19-9. Abdominal CT disclosed an about 2.1×0.9 cm sized soft tissue density in hilum with both intrahepatic duct (IHD) dilatations and an about 3×2.1 cm sized arterial enhancing lesion at segment 8 of the liver. Patient received 15 cycles of Gemcitabine/Cisplantin chemotherapy from February 27, 2013 to December 31, 2013. Caudate lobectomy of liver, segmental resection of bile duct and Roux-en-Y hepaticojejunostomy was performed on February 10, 2014. The final pathologic report showed double primary liver cancer, combined hepatocellular-cholangiocarcinoma in common hepatic bile duct and scirrhous type of hepatocellular carcinoma in segment 1 of the liver. This is a very unusual case in which combined hepatocellular-cholangiocarcinoma confined in the large bile duct and two rare hepatic cancers coexisted.

A number of studies have shown the value of fine needle aspiration cytology for the diagnosis of breast lesions, but reports on the comparison of cytologic and histologic variations of breast cancers are few. We reviewed histologically proven 106 breast aspirates with an emphasis on the cytology of ductal carcinomas and of an area of uncertain atypia. Positive and negative predictive values of breast aspiration cytology were 100% On review of the cases originally diagnosed as atypia of uncertain nature (19 %), features more suggestive of malignancy or benignancy were recognizable in most underdiagnosed cases and a half of overdiagnosed cases, respectively. However, indistinguishable atypism also remained. Thirty seven cases out of 53 infiltrating duct carcinomas revealed malignant cytology, with variations in background, cellularity, morphology of cell groups, and extent of isolated tumor cells. When classifying the infiltrating duct carcinomas into scirrhous, solid-tubular, and papillotubular types, scirrhous type frequently appeared as irregularly shaped tight or loose cell clusters, and solid-tubular type as round-margined cell balls.

In order to compare cytologic findings ol breast carcinoma in fine needle aspiration cytology (FANC) with histologic findings and prognostic factors including histologic grading, lymph node metastasis and stage, 79 cases of infiltrating ductal carcinoma diagnosed by FANC and confirmed by histology were analysed. We especially attempted to col relate nuclear grade, cellularity and smear pattern with histologic grade, type, status of lymph node metastasis and stage. The results are as fellows. 1. High nuclear grade was correlated with high histologic grade, lymph node metastasis and advanced stage. 2. Individual cell pattern was more frequently identified in high histologic grade and scirrhous or solid-tubular type than in low histolgic grade and papillotubular type. 3. Cellularity increased with higher histologic grade and lymph node metastsis. However cellularity was low in scirrhous type. 4. There is no relationship between nuclear grade and histologic type, between smear pattern and lymph node metastasis or stage, and between cellularity and stage. These results suggest that cytologic findings of breast carcinoma such as nuclear grade, cellularity and smear pattern are indicative of histologic findings in relation to histolgic grade and type. Especially, nuclear grade of FANC may yield valuable prognostic information.

목적: 담관암의 진단과 치료 평가를 위해서 여러 영상학적 방법이 이용되나 성장 형태를 포함한 질환의 성상이 아주 다양하고 종양과 주변 조직간의 대조도가 낮은 경우 발견이 어렵고 주로 종양 부분에 대한 국소 영상을 시행하여 질병의 전신 평가에는 충분하지 못할 수 있다. 이러한 점을 보완하기 위하여 $^{18}$F-FDG PET에 대한 연구가 이루어 지고 있는데, 본 연구에서는 담관암의 발생위치와 성장형태에 따라 $^{18}$F-FDG 섭취양상의 변화와 그에 따른 임상적 의의를 알아보고자 하였다. 대상 및 방법: 2005년 4월부터 2008년 5월까지 담관암으로 진단 받고 PET/CT를 촬영한 환자를 대상으로 하였다. 위치에 따른 담관암의 분류는 간내담관암과 간외담관암으로 나누고 간외담관암은 간문부암과 원위부 담도 암으로 나누었다. 간외담관암은 다시 그 성장형태에 따라 경화형, 결절형, 용종형으로 분류하여 PET양성인 환자들 중 SUV$_{max}$를 비교하였다. 결과: 총 82명의 담도암 환자들 중PET양성을 보인 환자는 81.7%이었다. PET 양성을 보인 간내담관암 환자는 23명으로 이들의 SUV$_{max}$는 9.4$\pm$4.1로 간외담관암보다 의미있게 높았다. 용종형의 간외담관암은 9명중 모두가 PET 양성이었고, SUV$_{max}$도 10.1$\pm$7.0으로 경화형, 결절형에 비해 높았다. 결론: 본 연구의 결과를 바탕으로$^{18}$F-FDG PET은 간외담관암보다는 간내담관암을 가진 환자의 진단에 더 유용할 것으로 보이며, 간외담관암의 진단에 있어서는 담도벽을 따라 침윤성으로 발생하는 경화형보다는 종괴를 형성하는 용종형에서 더 의미있는 검사방법이 될 수 있겠다.
