Cutaneous melanoma frequently metastasizes to the gastrointestinal tract, although clinical manifestations are uncommon. Acute intestinal obstruction due to small bowel intussusception caused by metastatic melanoma is a rare and life-threatening presentation. We report the case of a 51-year-old man with a history of cutaneous melanoma who presented with acute bowel obstruction. Abdominal computed tomography revealed small bowel intussusception with upstream dilation, associated with diffuse hepatic and peritoneal metastases. Emergency laparotomy confirmed intussusception caused by a metastatic small bowel lesion. Segmental small bowel resection with double-barrel ileostomy and peritoneal biopsies was performed. Histopathological analysis confirmed metastatic melanoma. Small bowel metastases from melanoma are often clinically silent and rarely diagnosed preoperatively. Computed tomography plays a pivotal role in diagnosis, allowing detection of intussusception and assessment of disease extent. Surgical intervention remains essential for managing acute complications and improving quality of life, despite the generally poor prognosis in metastatic disease. Although rare, small bowel intussusception should be considered in patients with melanoma presenting with acute intestinal obstruction. Prompt computed tomography diagnosis and surgical management are crucial in emergency settings.
