Abstract

Histopathological observations on a epidermal papilloma of wild red halibut (Hippogossoides dubius) caught at the area around Echung Island and Gogunsan Islands were done. The papilloma formed on the dorsal fin was the same color with the body on the ocular side but black on the non-ocular side. Under light microscopy, the tumor on the skin was very similar to epithelial papilloma supported by connective tissue. X-cell-like cells in the tumors were large and eosinophilic with a centrally-located, large nucleus. But the characteristic large nucleolus in the nucleus of the x-like cells was indistinct clear in this specimen because about 6-9 hours have passed after catching the fish and autolysis have occurred.

2009년 1월 6일경 어청도~고군산군도 사이에서 채낚기로 어획되어 군산수협 위판장에서 입수한 홍가자미의 피부 유두종을 병리조직학적으로 검사한 결과 저서성 어류에 발생되고 있는 상피성 유두종으로 종양의 내부는 특징적인 x-cell로 구성되어 있었다. 그러나 x-cell의 핵내의 특징인 대형의 핵인은 시료채취 후의 자가 분해에 의한 탓인지 관찰할 수 없었다.
