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.
