Cecal lipoma with pseudomalignant features: a case report and review of the literature.
Colonic lipoma is a well-documented benign neoplasia, endoscopically appearing as a smooth round yellowish polyp with a thick stalk or broad-based attachment. We describe a 63-year old woman with persistent abdominal pain, in whom colonoscopy revealed a cecal mass with malignant features. Based on the colonoscopy findings, right hemicolectomy was laparoscopically performed for a presumptive diagnosis of a cecal adenocarcinoma, but histological examination revealed a colonic lipoma with overlying mucosal ulceration.
