Abstract
Muscular lesion was detected in a 23-month-old castrated bull encountered at Kyungsan slaughter house. The lesion appeared as fat intervening muscle fibers. The affected animal had no clinical signs. On microscopic examination, there was replacement of many muscle fibers by normal fat cells. Numerous fat cells were located between muscle fibers. Remaining skeletal muscle cells were in degenerative process, and thus abnormal skeletal muscle cells had loose fibers while normal had intact ones. The advent of inflammatory cells is not at the lesion, which is unique view in steatosis.
2002년 5월 도축중 발견된 거세수소의 근육 병변에 대한 검사 의뢰가 들어왔다. 이 병변의 육안적 소견은 광범위한 근육의 지방침윤이었고, 병리조직학적 검사에서 근섬유가 지방조직에 의해 대치된 것이 관찰되었으며, 기타 염증 소견은 관찰되지 않았다. 본 증례는 골격근의 광범위한 부분이 지방조직으로 대치된 지방증(steatosis)으로 진단되어 이에 보고하는 바이다.
