ABSTRACT
Colonic lipomas are rare benign tumors. Colonic intussusception is an uncommon complication of colonic lipoma. The current study presents an unusual case of a 4-cm symptomatic lipoma of the transverse colon causing colonic intussusception. A 65-year-old female was admitted to Wenzhou Central Hospital (Wenzhou, Zhejiang, China) with intermittent pain in the left abdomen that had been present for two weeks. Colonoscopy revealed a 4×5-cm intraluminal spherical mass with erosional mucosa 60 cm above the anal verge, indicating the presence of a malignant gastrointestinal stromal tumor. Contrast-enhanced computed tomography revealed a well-defined fatty tissue mass of 4 cm in diameter in the distal transverse colon proximal to the splenic flexure, with intussusception. The patient underwent segmental resection of the transverse colon and intraoperative frozen sections were obtained. The intraoperative frozen sections revealed a submucosal lipoma of the transverse colon and thus, a conclusive diagnosis was achieved. The patient was followed up for one year and 10 months following the segmental resection of the transverse colon, with a good prognosis. This study may increase clinical awareness with regard to colonic lipomas. Furthermore, open surgery combined with use of intraoperative frozen sections should be recommended for large symptomatic colonic lipomas accompanied by colonic intussusception, thus avoiding unnecessary radical resection and improving patient prognosis.

Mentions: In March 2012, a 65-year-old female was admitted to Wenzhou Central Hospital (Wenzhou, Zhejiang, China) with intermittent pain in the left abdomen that had been present for two weeks. The patient had no past history of cancer and no family history of colorectal cancer. The physical examination was unremarkable. The laboratory results revealed a white blood cell count of 12.5×109 cells/l, a neutrophil count of 9.2×109 cells/l (73.2%) and a C-reactive protein level of 10.4 mg/l. Tumor markers were within the normal ranges. Colonoscopy revealed a 4×5-cm intraluminal spherical mass, 60 cm above the anal verge, which prevented further progression of the endoscope. The mass was covered by a 2×3-cm superficial mucosal erosion, indicating the presence of a malignant gastrointestinal stromal tumor (Fig. 1). In addition, a biopsy of the mass revealed numerous ulcerative lesions with local epithelial regeneration. Furthermore, contrast-enhanced computed tomography (CT) revealed a well-defined fatty tissue mass of 4 cm in diameter in the distal transverse colon proximal to the splenic flexure (Fig. 2A), with intussusception (Fig. 2B and C) and local bowel-wall thickening.
