Submucous Colon Lipoma: A Case Report and Review of the Literature

Hong Zhang et al. World J Gastroenterol.

Abstract

Colon lipoma is remarkably rare in clinical practice. We reported a case of ascending colon lipoma in an 83-year-old woman. She was asymptomatic with a lipoma of 35 mm x 30 mm x 24 mm in size which was found by routine colonoscopy. Right hemicolectomy was performed uneventfully. The diagnosis was made by histological examination. Reviewing the literature and combining with our experience, we discussed the clinical features, diagnosis and treatment of this uncommon disease.

The overlying mucosa was smooth, and the lesion was soft and compressible; B: The preoperative examination: Barium enema revealed an ovoid filling defect with smooth border at the proximal area of colon hepatic flexture; C: The preoperative examination: CT scan found a pedunculated neoplasm protruding into the lumen at the site of ascending colon with sharp margin and soft tissue density.

A: The macroscopic inspection: Macroscopic inspection of the resected colon segment showed a smooth round polypoid submucous tumor with elastic character and 35 mm×30 mm×24 mm in size; B: The macroscopic inspection: Fault of the specimen demonstrated the tumor with pedunculated appearance. The base of the lesion was 8 mm in size. The tumor was covered by normal mucosa and had uniform parenchyma in bright yellow color (one scale mark = 1 mm).
