ABSTRACT

Background: Colonic lipomas are the second most common benign neoplasm of the colon after adenomatous polyps; however, it is still a rare entity with a reported frequency of 0.2 to 0.3%. These lipomas are usually asymptomatic but, depending on size, may produce some symptoms. It is important to recognize the presentations of these benign tumors because they may be mistaken for malignant tumors and result in major unnecessary procedures.
Clinical case: We present the case of a 76-year-old female with transanal bleeding, constipation, abdominal distention, and cramping abdominal pain. During colonoscopy the presence was noted of a tumor occluding the intestinal lumen of the sigmoid colon. CT scan demonstrated no metastatic disease and the presence of a well-defined tumor in the colon lumen. Tumor markers were negative and biopsies demonstrated a nonspecific pattern. We performed segmental resection of the sigmoid colon, finding an intraluminal tubular-shaped tumor. Pathological study of the surgical specimen reported colonic lipoma.
Conclusions: Colonic lipomas are rare but may be found during routine examinations. Treatment depends on tumor size and localization.
