Equine small intestinal angiomatosis.
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. . De multiples nodules rouges surélevés distribués de manière multifocale le long de la surface séreuse du jéjunum viable et non-viable furent identifiés chez un cheval mâle castré âgé de 24 ans soumis à une chirurgie pour le retrait d’un lipome étranglant autour du jéjunum. Histologiquement, ces nodules consistaient en de nombreux canaux vasculaires remplis de sang dilatés de manière significative et variable, et tapissés par une couche unique de cellules endothéliales aplaties et bien différenciées avec à l’occasion des thrombi à l’intérieur d’un stroma fibreux légèrement épaissi. Un diagnostic d’angiomatose intestinale fut proposé. Au meilleur de la connaissance des auteurs, ceci constitue le deuxième rapport d’angiomatose du petit intestin chez un cheval.(Traduit par D Serge Messier).

This research article investigates a rare case of intestinal angiomatosis found in a 24-year-old horse during a surgical operation to remove a strangulating lipoma around the jejunum. Upon examination, this is only the second reported case of small intestinal angiomatosis in a horse and provides useful insights for future research and understanding of the condition.
Introduction
- The paper commences with a description of a 24-year-old neutered male horse that was undergoing surgery to remove a strangulating lipoma around the jejunum.
- During the surgery, several red, elevated nodules were found scattered along the serosal surface of both the normal and the nonviable jejunum. These nodules formed the main focal point of the research.
Findings
- Upon histological examination, the researchers found these nodules to be filled with significantly and variably dilated, blood-filled vascular channels.
- The channels had a single layer of flat, well-differentiated endothelial cells and occasional thrombi within a slightly thickened fibrous stroma.
- Based on these histopathological features, a diagnosis of intestinal angiomatosis was formulated.
Significance
- The study highlights a rare case of small intestinal angiomatosis in a horse, marking only the second report of such a case in scientific literature.
- The findings of this study contribute to the limited knowledge base on the topic, potentially helping veterinary practitioners better understand and manage similar future cases.
