Lipoma of the sigmoid colon

Abstract

Introduction. Lipoma is a benign tumor of adipose tissue, the most common tumor of the human body soft tissues. As such, it can be found almost anywhere in the human body including the gastrointestinal system (incidence below 0.5%), but rarely in the sigmoid colon. Case report. This is a case report on symptomatic polyp of the sigmoid colon, which after one year, at control colonoscopy, caused suspicion to malignancy. Endoscopically diagnosed polipoid lesion was laparoscopically removed. The pathohistological diagnosis determined benign, submucosal, incapsulated lipoma of the sigmoid colon. Conclusion. Although lipomas of the gastrointestinal tract are rare, this case clearly indicates that we should not prematurely and without histological confirmation of malignancy do more extensive resection for a suspected malignancy.
