Laparoscopic excision for small intestinal mesenteric tumour diagnosed Schloffer tumour

This report presents a case of Schloffer tumour at the small intestinal mesentery, mimicking a malignant tumour, treated laparoscopically. Six years prior, a 57-year-old woman underwent laparoscopic salpingo-oophorectomy for a benign, cystic, ovarian tumour, but she had no history of malignancy. She was treated at an outpatient clinic for gastrointestinal complaints and was relieved of these symptoms. Abdominal computed tomography showed an incidental mesenteric tumour of the small intestine, tending toward growth. Due to the tumour's malignant potential, laparoscopic examination was performed. A spherical tumour with a base in the jejunum mesentery was observed. It was removed without damage. The post-operative course was uneventful, and the patient was discharged 3 days after the operation without complications. Histological diagnosis showed this to be a Schloffer tumour, but no malignancy was observed. Unidentified intraperitoneal tumours in patients with surgical histories may be Schloffer tumours, and this should be kept in mind.
