Plain-English summary
A newborn foal was found to have rectal bleeding and was diagnosed with a mass in the rectum and a condition where part of the intestine folds into itself, called intussusception. During surgery, the mass was examined and found to have fluid-filled spaces lined with specific cells, surrounded by muscle tissue. While the mass had some similarities to conditions seen in humans, it didn't completely match any known conditions. The treatment involved surgical exploration, but the abstract does not specify the outcome of the surgery or the foal's recovery.
Abstract
A neonatal foal with signs of rectal bleeding was diagnosed with an intraluminal rectal mass and intussusception on surgical exploration of the abdomen. Histologically, the mass consisted of cystic spaces lined by simple columnar epithelium with numerous goblet cells and was surrounded by thin bands of smooth muscle in a myxomatous stroma. Although the mass shared similarities with retrorectal cystic hamartoma (tailgut cyst) and juvenile polyps, described in human medicine, location and histologic findings were not entirely consistent with either condition.
