Plain-English summary
A 24-year-old neutered male horse was found to have multiple red, raised nodules on the surface of his small intestine during surgery to remove a lipoma (a type of fatty tumor) that was causing a blockage. These nodules were made up of enlarged blood vessels filled with blood and were surrounded by a thickened layer of tissue. The condition was diagnosed as intestinal angiomatosis, which is a rare finding in horses. This case is only the second reported instance of this condition in a horse.
Abstract
Multiple red, raised nodules multifocally distributed along the serosal surface of the normal and the nonviable jejunum were identified in a 24-year-old neutered male horse undergoing surgery for removal of the strangulating lipoma around the jejunum. Histologically, these nodules consisted of many significantly and variably dilated, blood-filled vascular channels lined by a single layer of flattened, well-differentiated endothelial cells with occasional thrombi within a mildly thickened fibrous stroma. A diagnosis of intestinal angiomatosis was proposed. To the best of the authors' knowledge, this is the second report of small intestinal angiomatosis in a horse.
