Lipomas are common non-epithelial benign tumors in the large intestine, frequently found in the proximal colon, particularly in the cecum.

bubble_chart Clinical Manifestations

It commonly occurs between the ages of 50 and 69, with a higher incidence in women than in men. Most patients are asymptomatic, but larger lipomas may present with abdominal pain, hematochezia, changes in bowel habits, intussusception, and, in rare cases, a palpable mass.

bubble_chart Auxiliary Examination

Endoscopic findings of a large intestine lipoma reveal a soft, yellow, round mass. Larger submucosal lipomas often protrude into the intestinal lumen, sometimes developing a pedicle. During biopsy, yellow material may occasionally be observed. Pathological examination shows mature adipocytes and fibrous stroma, confirming the diagnosis. On X-ray, the lesion appears as a smooth, pedunculated or broad-based intraluminal mass with variable morphology. The filling defect may change shape during barium enema due to external compression or emptying.

The treatment principle for this disease is local excision. For cases that cannot be removed endoscopically or have developed intestinal wall necrosis, or when intussusception reduction fails, surgical resection is recommended.
