Examination of the reproductive tract revealed the presence of a large mass attached to the uterine wall via a wide and short peduncle in both cases. The mass expanded into the uterine lumen in the mare and into the abdomen in the cow. Both masses were removed using a minimally invasive endoscopic approach and a vessel‐sealing and dividing device.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Minimally invasive surgical resection of a subserosal and a submucosal leiomyoma with maximal sparing of uterine tissue resulted in a short convalescence period and apparent return to breeding function in a cow and a mare. Use of a vessel‐sealing and dividing device provided excellent hemostasis and decreased tissue handling.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Leiomyoma with short, wide, and thick peduncles were treated successfully in a cow and a mare with minimally invasive endoscopic approaches aiming at maximal uterine tissue preservation.</jats:p></jats:sec>
