  • Cystic lesions of the liver are commonly encountered in routine clinical practice with a reported prevalence of 15%-18%. They may range from a benign simple developmental cyst to a malignancy. Therefore, an accurate diagnosis is essential for adequate management. Cystic tumors of the liver are classified based on the content (mucin containing or not), presence of ovarian stroma, and biliary communication. Biliary cystadenoma are a group of hepatobiliary neoplasia which by definition must be multilocular, lined by a columnar epithelium, and have a densely cellular ovarian stroma. We report a case of a cystic lesion in the hilar region of the liver, which had features of biliary cystadenoma on the preoperative imaging. However, on exploration was found to be a diverticular variant of type V choledochal cyst arising from both hepatic ducts. We have discussed the preoperative imaging features, intraoperative cholangiogram, and the management of this cystic lesion.

  • A seven-year old female captive Japanese macaque (Macaca fuscata) was mobbed by its cage mates and subsequently died due to trauma. An incidental finding of multiple biliary cystadenoma in the liver is herein reported. Grossly, multiple small cysts were observed throughout the surface of the liver. One particular cyst that measured $1.3\times1.2\times1.0cm$ and contained mucinous fluid was observed in the center of the liver. Microscopically the cysts were lined by biliary epithelium that varied from simple cuboidal to columnar cells. Signs of malignancy and metastasis to other organs were not observed. This is the first report of biliary cystadenoma in Japanese macaque.

  • A 50-year-old male presented gradually growing pancreatic body mass. An abdominal computed tomography showed a 9.9-cm mass, larger than the 8.9-cm mass one year ago. As the patient did not have complaints for any symptomatic problems, the gastroenterologist decided to check it with regular follow-up. However, as the tumor grew faster than expected, the patient was recommended for surgical resection. Laparoscopic pylorus preserving pancreaticoduodenectomy was done. Since the tumor abutted to the superior mesenteric vein and the portal vein, wedge resection of vessel was inevitable. Pathology was serous cystadenoma. The patient was discharged without postoperative complications. Herein, we report this case with asymptomatic large serous cystic neoplasm treated by laparoscopic approach. The appropriateness of current guidelines for surgery in serous cystic neoplasm is also discussed.
