Obesity is a chronic disease with pandemic levels of prevalence worldwide. The most often performed bariatric procedure is sleeve gastrectomy. Although the patient's history may not indicate preoperative imaging studies, coincidental findings of unexpected pathology are not uncommon, such as leiomyoma. A 41-year-old female was scheduled to laparoscopic gastric sleeve with no contraindications for surgery. A tumor-like mass was identified on the left lateral face of the distal third of the esophagus. Trans-surgical endoscopy and pneumatic test were performed to rule out any type of communication. The surgeon managed to remove the tumor mass, that was sent to histopathological study, and concluded the procedure without complications. Benign tumors of the esophagus are rarely found lesions. Occasionally unexpected findings may occur during surgery, and they should be resolved intraoperatively when possible to allow the completion of the originally planned surgical procedure.
