Abstract

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.

동물원에서 사육 중이던 7세령 암컷 일본원숭이가 짝짓기 과정에서 피부에 외상을 입은 후 치료 도중 폐사하였다. 부검시 간에서 $1.3\times1.2\times1.0cm$ 크기를 비롯한 다양한 크기의 다발성 낭포가 관찰되었으며 낭포내에 점액성 액체가 저류되어 있었다. 현미경 소견상 낭포는 담관 상피세포로 덮혀 있었고 입방상피에서 원주상피까지 다양하였으며 대부분 단층이었으나 일부는 여러층으로 덮혀 있었다. 악성도나 다른 장기로의 전이 소견은 찾을 수 없었다. 본 증례는 일본 원숭이에서 발견된 첫 번째 담관 낭샘종 증례이다.
