Plain-English summary
Two horses that had been experiencing ongoing, occasional belly pain (colic) were examined after they passed away. During the examination, veterinarians found a thickened area in a part of the small intestine called the duodenum. Further testing showed that this thickening was due to a type of tumor called leiomyosarcoma, which is made up of muscle-like cells. This tumor was causing a blockage in their intestines. Unfortunately, both horses had a serious condition that led to their deaths.
Abstract
Two horses affected by chronic, intermittent colic were found, at post-mortem examination, to have localized annular thickening of a segment of the duodenum. Histological examination of the lesion in both cases revealed a tumour composed of bundles of oval or spindle-shaped cells that stained as muscle with van Gieson stain. The histological diagnosis was leiomyosarcoma. The tumour had caused partial bowel obstruction in both horses.
