Abstract

Abstract: Colonic leiomyomas are rare. Their clinical presentation ranges from asymptomatic polyps detected on endoscopy to large symptomatic abdominopelvic masses. Imaging findings are usually non-specific, and percutaneous biopsy might help with differential diagnosis. However, radical surgery with negative margins is ultimately needed to rule out malignancy. We describe an uncommon presentation of a colonic leiomyoma mimicking a right hepatic lobe tumor on preoperative imaging. The robotic approach allowed a precise abdominal exploration with confirmation of colonic and hepatic infiltration and subsequent oncological en-block resection. Surgeons operating on hepatic tumors close to the right colic flexure should be aware of this diagnosis.
