Abstract

Small bowel is a well-described site of malignant melanoma; however, it is a rare cause of intussusception. A patient presented with malignant melanoma causing jejunojejunal intussusception 11 years after resection of melanoma-in-situ. The patient was managed with exploration and resection. Despite complete resection of melanoma-in-situ and limited literature about its metastatic potential, malignant melanoma as a lead point for intussusception should be on the differential for any patient with pertinent history. To our knowledge, this appears to be the first case of melanoma-in-situ causing small bowel intussusception.
