Lipomas of the colon are relatively rare benign soft tissue tumors derived from mature adipocytes of mesenchymatic origin. During colonoscopy, surgery or autopsy they are generally discovered incidentally. Most cases are asymptomatic, with a small tumor size, and do not need any special treatment. However, in the cases with larger in size of tumor some symptoms such as anemia, abdominal pain, constipation, diarrhea, bleeding, or intussusception may be presented. We reported a 47-year-old woman with colonic intussusception in the descending colon caused by colonic lipoma and diagnosed after surgical exploration for obstructive colonic mass.

结肠脂肪瘤是一种相对罕见的良性软组织肿瘤，由间充质来源的成熟脂肪细胞衍生而来。在结肠镜检查、手术或尸检过程中，它们通常是偶然被发现的。大多数病例无症状，肿瘤体积小，不需要任何特殊治疗。然而，在肿瘤体积较大的病例中，可能会出现一些症状，如贫血、腹痛、便秘、腹泻、出血或肠套叠。我们报告了一名47岁女性，因结肠脂肪瘤导致降结肠肠套叠，并在对梗阻性结肠肿块进行手术探查后确诊。
