INTRODUCTION - Submucous lipomas are rare tumors of the colon and may be misdiagnosed as cancer because of their exophytic, polypoid growth and threatening bowel obstruction. CASE REPORT - A protruding, ulcerated and firm tumor preventing the investigation of the coecum was found by endoscopy in the ascending colon of a 50-year-old woman, who was subsequently operated on. The preoperative biopsy revealed only necrotic debris. Right hemicolectomy was performed because of threatening bowel obstruction and the presumed diagnosis of cancer. The tumor proved to be a 4 cm-large pedunculated submucosal lipoma. CONCLUSION - Despite recent diagnostic developments and the availability of better tools for the preoperative diagnosis of colonic lipomas, these tumors may still be misdiagnosed as carcinomas. Several circumstances contradict malignant dignity, such as: the relative circumscription of the mass, the trophic and only partial ulceration of the surface which is covered by normal mucosal layer elsewhere. To avoid unnecessary radicality in treatment, colon tumors with an uncertain preoperative diagnosis should undergo further diagnostic steps in order to clarify their nature. This could allow a more optimal therapeutic planning.
