Abstract:
Objective To summarize our experiences in the diagnosis and treatment of giant colonic lipoma,and enhance awareness of the disease and avoid misdiagnosis.Methods We retrospectively analyzed the clinical data of 5 cases of giant colonic lipoma that were mistaken for colon cancer,and evaluate the possible reasons of misdiagnosis.Results Colonic lipoma is an uncommon benign tumor.Most cases with larger tumor size were misdiagnosed as colon cancer when they suffered from the symptoms of abdominal pain,bloody stool,abdominal mass,even bowel obstruction and intussusception.Barium enema and colonoscopy are important diagnostic means.Contrast enhanced CT scan can provide definitive topographical information identifying a colonic lipoma.Surgical resection was performed in all the 5 cases.Conclusion Giant colonic lipoma with intussusception can mimic a colonic carcinoma leading to misdiagnosis.
