Giant colon lipoma

Abstract

Colonic lipomas are rare benign nonepithelial tumors. Generally they are smaller than two centimeters and asymptomatic, incidentially detected and do not need any medical treatment. Large and symptomatic lipomas of colon are extremely rare. Besides, the diagnosis can be made after the histopathological analysis of the resected specimen. A fifty six year old woman presented with stomach ache, puffiness in the abdomen and weight loss complaints. In colonoscopy, at the hepatic flexure there was a 8x6 cm. submucosal mass which was frequently causing ulcer of the mucosa and was necrotic, nearly plugging the lumen. There was an ovoidal mass about 8.5 cm. by the signal density alike with fat tissue in magnetic resonance imaging. Since it was symptomatic and could not be diagnosed; a laparascopic right hemicolectomy was performed in the patient. During the histopathological analysis of the specimen, a submucosally situated lipoma was determined. The patient was discharged from the hospital on the seventh day after the operation without any problem. Diagnosing lipomas during the pre-operation period may be difficult, especially when the lesion is big and the ulcer may be confused with malignancy. To avoid the complications, in colon lipomas and to eliminate the malignancy risk surgery, may be needed in large symptomatic colon lipomas.
