Milk of calcium bile or limy bile is a rare disorder in which the gallbladder lumen is filled with a thick, paste-like, radio-opaque material. Churchman first reported a case of curious deposition of calcium salts within the gallbladder in 1911. Volkmann first used the term Kalkmilchgalle or milk of calcium bile in 1926. The radio-opaque material is almost entirely composed of calcium carbonate by weight. The mechanisms by which bile turns limy and radio-opaque or the time required for this biochemical alteration to occur are not well understood. The limy bile is found mostly in a gallbladder complicated by cholecystitis. Recently, we experienced a 33 year old woman who had a milk of calcium bile in the gallbladder lumen. We report this case with a review of literature.

Nowadays increasing use of abdominal ultrasound in routine check-up may increase the detection rate asymtomatic cystic lesions of pancreas. Even through the majority of the cystic lesions of pancreas is pseudocyst, about 10-15% of those lesions are caused by pancreatic cystic tumor. In the pancreatic cystic tumor, especially, mucinous cystic tumor should be exicised due to its malignant potential, while the pancreatic pseudocyst or serous cystic tumon can be observed for a period or treated medically. Several clinical, radiological, biochemical and pathologic guidelines have been developed in order to distinguish among them. Among pancreatic cystic tumors, mucinous cystic adenocarcinoma is very rare and accounts for only 1% of all pancreatic neoplasms. Unlike extremely poor prognosis of pancreatic adenocarcinoma, mucinous cystic adenocarcinoma has an indolent course and shows a good prognosis after its curative resection. Recently we experienced a 69-year-old woman who had a mucinous cystic adenocarcinoma of the pancreas. We report this case with a review of literature.

Infectious mononucleosis is an acute lymphoproliferative disease that is most common in children and young adults and is caused by Epstein-Barr virus.

Characteristic clinical feastures include : 1) fever, sore throat, and lymphadenopathy ; 2) an associated absolute lymphocytosis greater than 50%, of which at least 10% are atypical lymphocytes in the peripheral blood ; 3) development of transient heterophil and persistent antibody responses against Epstein-Barr virus ; and 4) abnormal liver function tests.

The most prevalent age of infectious mononucleosis in Korea was less than 5 years old and it has been very rare in adulthood. However, recently in Korea, possibly due to the increasing number of people who are non-immune to Epstein-Barr virus, the age range seems to be increasing from young childhood to over 10 years old and even to adulthood. We present a 19-year-old man who showed typical clinical features of infectious mononucleosis.
